PHP - Every 3rd Iteration Of A Loop
To solve a bigger issue I'm having in WordPress, I have thrown together this basic script in PHP script to help me get to the bottom of it.
Basically, I am trying to add a <hr /> tag after every 3rd paragraph: http://www.mattpealing-server.co.uk/~freshmat/wp-content/themes/match2move/test.php With the following code: <?php $count = 0; ?><?php while($count < 20) : ?><span><p><strong><?php echo $count; ?>:</strong> Lorem ipsum dolor sit amet, consectetuer adipiscing.</p></span><?php if ($count % 3) : ?><hr /><?php endif; ?><?php $count ++; ?><?php endwhile; ?>() However if you notice, this output just doesn't turn out like this! Does the operator I'm using not test if $count is a multiple of 3? Similar TutorialsSo I have a very simple for loop that I am populating a list with levels and exp required to achieve the next level. I have been using a sandbox to test my output and have also created an excel sheet to replicate the data to verify the content. This code was not mine from the beginning and in creating the spreadsheet I discovered the flaw. Below is the code I am trying to fix:
function experience($L, $pres = 0) {
$a = 0;
$end = 0;
for ($x = 1; $x < $L; ++$x) {
$a += $x * round($x + 5 * pow(4, ($x / 300)));
}
if ($x > 199) {
$a += $x * round($x + 7 * pow(4, ($x / 290)));
}
if ($x > 399) {
$a += $x * round($x + 11 * pow(4, ($x / 280)));
}
if ($x > 599) {
$a += $x * round($x + 19 * pow(4, ($x / 270)));
}
if ($x > 799) {
$a += $x * round($x + 35 * pow(4, ($x / 260)));
}
if ($x > 999) {
$a += $x * round($x + 67 * pow(4, ($x / 250)));
}
return round($a / 1.25);
}
Below is the troubleshooting I am attempting to do (Modified and simplified for and while loop):
//for loop
$no = 200;
$a = 0;
for ($x = 1; $x < $no; ++$x) {
$a += $x + 1;
}
if ($no > 199) {
$a += $x + 2;
}
echo $a;
//while loop
$no = 200;
$a = 0;
$x = 1;
while (($x - 1) < $no) {
$a += $x * round($x + 5 * pow(4, ($x / 300)));
$x++;
if ($x > 199) {
$a += $x * round($x + 7 * pow(4, ($x / 290)));
}
}
echo $a;
Upon request I can also provide snipets of the excel sheet. So the gist of what the issue I am having is this. Between level 199 and 200 the iteration of the loop is running one extra time through the initial formula. As you can tell at level 200, 400, 600, 800 and 1000 I want this formula to change so that it simplifies the amount of exp required to achieve the next level. I can not for the life of me figure out how to restrict the loop while still allowing the values 200 up to run through it for the first 199 iterations. The output I should get from the primary code for levels 199 through 201 are as follows: 199 = 200 = 201 = At level 199 I am good but for whatever reason it runs one additional iteration at the level 1-199 formula and then moves on to the 200 level formula messing up the values. Any and all help is much appreciated. I am a novice hobbyist at best and have been doing this for many, many years now but sometimes I get stumped. I chalk it up to lack of proper training and time to really be serious with it. Thanks in advance....NICON I am doing some study on using time() and date() and i just wrote this simple for loop to add one day to each iteration with +$i and its echoing the unix timestamp as opposed to the correctly formated date as it should be based on my code. Anyone have any idea why this is not working as expected? for($i=0; $i < 50; $i++) { echo $time = time()+$i . "<br />"; // add a day on each iteration echo date('y-m-d', $time) . "<br />"; // should echo 10-12-02, 10-12-03, 10-12-04, etc.. } what am i doing wrong here? arrgggg! maybe its too late for this s$%^#!
$start = 0; hi I'm coding a page and I was trying to iterate an iteration. but it doesn't seem to work. is this possible in php? Code: [Select] $pageTpl->setIteration('iPlaylist'); // loop all collections and output them foreach ($playlists as $playlist) { // assign collection & urls in template $pageTpl->assignIteration('playlist', $playlist['Title']); $pageTpl->refillIteration(); $pageTpl->setIteration('iMusic'); foreach ($songs as $song){ $pageTpl->assignIteration('path', STREAMING_PREFIX.substr($song['Filename'], 7)); $pageTpl->assignIteration('songId', $song['SongId']); $pageTpl->assignIteration('title', $song['Title']); $pageTpl->assignIteration('artist', $song['Artist']); $pageTpl->assignIteration('time', FYMFunctions::Sec2hms($song['Length'])); $pageTpl->assignIteration('genre', $song['Genre']); $pageTpl->assignIteration('delete', 'removeSong('.$song['SongId'].')'); $pageTpl->refillIteration('iMusic'); } // parseIteration $pageTpl->parseIteration('iMusic'); } // refillIteration $pageTpl->refillIteration(); // parseIteration $pageTpl->parseIteration('iPlaylist'); this is the piece of code... did I do anything wrong? Hello,
Here is my code:
<?php
require 'vendor/autoload.php';
$client = new Elasticsearch/Client();
$root = realpath('~/elkdata/for_elk_test_2014_11_24/Agencies');
$iter = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($root, RecursiveDirectoryIterator::SKIP_DOTS),
RecursiveIteratorIterator::SELF_FIRST,
RecursiveIteratorIterator::CATCH_GET_CHILD);
$paths = array($root);
foreach ($iter as $path => $dir) {
if ($dir -> isDir()) {
$paths[] = $path;
}
}
//Create the index and mappings
$mapping['index'] = 'rvuehistoricaldocuments2009-2013'; //mapping code
$mapping['body'] = array (

$client ->indices()->create($mapping)
//Now index the documents
for ($i = 0; $i <= count($paths); $i++) {
$params ['body'][] = array(
'index' => array(
'type' => 'documents'
'body' => array(
'foo' => 'bar' //Document body goes here

);
//Every 1000 documents stop and send the bulk request.
if($1 % 1000) {
$responses = $client->bulk($params);
// erase the old bulk request
$params = array();
// unset the bulk response when you are done to save memory
unset($responses);
}
}
?>
I am looking to index a large amount of documents using elastic search and php. I have a very complex directory filled with other directories that i need to index into an array. I wanted to see if my code looked right, and if not what am I doing wrong?
Thanks,

Hello, I have two classes: Code: [Select] abstract class Serializable { public function serialize() { foreach($this as $member => $value) { $publicObject->$member = $value; } return $publicObject } } class ToSerialize extends Serializable { public function otherSerialize() { foreach($this as $member => $value) { $publicObject->$member = $value; } return $publicObject } } $foo = new ToSerialize(); $foo->serialize(); //This will return one thing $foo->otherSerialize(); //This will return something different Why does this happen? Evening everyone and Merry X-Mas (Happy Holidays) or whatever fits you best.... I have been trying over and over for about 12 hours to figure out how to get data from a specific JSON response and assign the specific values to a new array key/value pair. The various ways I have tried to figure this out are numerous so i'm going to avoid the runnig list of "I trieid this...and this...and this... etc etc." just understand I have reached a dead end point where I need help badly.
Here is what our end goal is:
"The company" is a "service industry" provider (plumbing, electrical etc. etc.) who wants to dispatch its technicians to new jobs based on which technician has the shortest travel time from any existing address where they already have a scheduled appointment that day and has available time in there schedule. Thus the dispatching system when a new service call is entered is going to give "recommended" technicians (up to 4) to be assigned the new service call based on the above mentioned criteria. (Efficient routing to save company gas cost)
1.) We have a "New service" street address assigned to the $to variable: $to = "4813 River Basin Dr S, Jacksonville FL 32207"; 2.) We will have "records" array which containes a series of records, each record consists of a ticket# a technician id# and a street address: $records = array( array("DV1012","30453423","9890 Hutchinson Park Dr Jacksonville, FL 32225"), array("DB3434","30404041","821 Orange Ave Crescent City, FL 32112"), array("DB3434","30605060","1972 Wells Road, Orange Park FL 32073"), array("DB4578","30605060","2 Independent Drive, Jacksonville FL 32202"), array("DB7841","30605060","5000 Norwood Avenue, Jacksonville FL 32208"), array("DB3235","30605060","9501 Arlington Expressway, Jacksonville FL 32225"), array("DB7894","30605060","Massey Avenue, Jacksonville, FL 32227"), array("DB2020","30121212","11200 Central Pkwy Jacksonville, FL 32224") ); 3.) We are going to prepare the records array for submission to Google's Distance Matrix API by URL encoding each array value into a single variable and then submit it: foreach ($records as $key => $value) {$from = $from.urlencode($value[2])."|";} $to = urlencode($to); $data = file_get_contents("//maps.googleapis.com/maps/api/distancematrix/json?origins=$from&destinations=$to&language=en-EN&units=imperial&mode=driving&sensor=false"); $res=json_decode($data) or die("Error: Cannot read object"); You may look at the ACTUAL live Google response from this he http://tiny.cc/i6eerx (We have applied <pre> and var_dump($res) to the output) We are looking to get the following information back: The distance and travel time between the "New Service" address ($to) and each of the address' in the $records array ($from), now once that information is returned from Google (JSON response) we need to parse the response and narrow it down to 4 or less (Based on the 4 lowest drive times) to form a new array which ends like this: $results = array( array("DV1012","30453423","2.3 Miles","8 mins"), array("DB3434","30404041","2.8 Miles","9 mins"), array("DB3434","30605060","4.6 Miles","13.8 mins"), array("DB4578","30605060","5.7 Miles","15.2 min") ); OUR PROBLEM: Everything up until the the Google API response is fine, but iterating over the multidimensional arrays within multidimensional arrays of the JSON response is just not coming together in my head (or 2 dozen code attempts). I am able to ECHO an individual value like ( echo $res->rows[0]->elements[0]->distance->text; ) but this has no value for the end result i need to get to. My last thoughts and efforts was that that I was going to have to embed foreach statements within foreach statements to drill down through the various arrays but that hasn't worked very well and it seems like it shouldn't be how it has to be done. I would appreciate any help in showing me how the iteration code should be written and any explanation about the code so i can wrap my head around it. I'm not entirely sure how to phrase the title, so I hope it's appropriate... I have an array which looks like the following.. Code: [Select] Array ( [contact] => Array ( [0] => Array ( [name] => Someone Cool [number] => 1234567890 ) ) [messages] => Array ( [0] => Array ( [message] => A message that was recieved [date] => 1234567890 [type] => 1 ) [1] => Array ( [message] => A message which was sent [date] => 1322175702616 [type] => 2 ) ) [calls] => Array ( [0] => Array ( [datetime] => 1320674980836 [type] => 1 [duration] => 7 [number] => 1234567890 ) [1] => Array ( [datetime] => 1320675327541 [type] => 2 [duration] => 638 [number] => 1234567890 ) ) ) [messages] can have anywhere between 40 and 3000 children [calls] can have anywhere from 0 to 200ish children ** These are generals, but realistically, either can have any number. What I'm trying to do is dump all messages and calls. The catch is this: When dumping a call, a check needs to be run against datestamps and only dump the next call coming out where the datestamp of the call is NEWER than the LAST message dumped, AND OLDER than the message that is to be dump in this cycle of the loop. What I have so far is the following... Code: [Select] foreach($vardump['messages'] as $message) { // So we have a reference point for the first call we're going to dump if(!is_numeric($last_message_stamp)) { $last_message_stamp = $message['date']; } if( trim($vardump['calls'][$calls_counter]['datetime']) > trim($last_message_stamp) && trim($vardump['calls'][$calls_counter]['datetime']) < trim($message['date'])) { // Dump the calls row! echo(" <div class=\"chatbubble-call\"> <div class=\"chatbubble-person\">".$vardump['contact'][0]['name']."</div> <p>".$vardump['calls'][$calls_counter]['number']."</p> <p>".date("h:i:s", $vardump['calls'][$calls_counter]['number'])."</p> <div class=\"chatbubble-datetime\">".date("l, j F, Y -- h:i:s", $vardump['calls'][$calls_counter]['datetime'] / 1000)."</div> </div> "); // Increase our calls index $calls_counter++; } // Begin dumping Texts out :D // Let's see which style type we're dumping out... if($message['type'] == 2) { // Message Sent echo(" <div class=\"chatbubble-sent\"> <div class=\"chatbubble-person\">Pat Litke</div> <p>".$message['message']."</p> <div class=\"chatbubble-datetime\">".date("l, j F, Y -- h:i:s", $message['date'] / 1000)."</div> </div> "); } else { // Message Recieved echo(" <div class=\"chatbubble-recieved\"> <div class=\"chatbubble-person\">".$vardump['contact'][0]['name']."</div> <p>".$message['message']."</p> <div class=\"chatbubble-datetime\">".date("l, j F, Y -- h:i:s", $message['date'] / 1000)."</div> </div> "); } // Reset our $last_messge_stamp variable $last_message_stamp = $message['date']; } I should also add that I am using the following queries to pull this date out of my database... Code: [Select] $sql_get_messages = "SELECT * FROM messages WHERE thread_number LIKE '%$the_thread%' ORDER BY epoch_date ASC"; $sql_get_calls = "SELECT * FROM calls WHERE number LIKE '%$the_thread%' ORDER BY datetime ASC"; $sql_get_contact = "SELECT * FROM contacts WHERE number LIKE '%$the_thread%' LIMIT 1"; But, I feel that this is horribly inefficient, and it doesn't work right... I only ever get a single call dumped. What am I doing wrong? I have an array of property details that prints to the page. Later on that same page, I would like to use one of the array's values as part of a mailto script, but I can't seem to figure out how to recall it. could someone point me in the direction of how I can make the array's values available for later use? I hope this is clear enough. Thanks Specific question with general application here. i am having some trouble with a loop and am getting some odd timing results specifically this is a WMI query on a hyper-v server retrieving disk information but im not sure the context of the query is relevant here. The main question is how come the first iteration of the loop is so much slower than the other iterations, it just doesnt seem to make sense to me unless ive done something stupid here i cannot see. any ideas ? Code: [Select] <?php $diskstart = microtime(true); // get the hard disk size try { $resultDisk = $wmi->ExecQuery("SELECT BlockSize,NumberOfBlocks FROM msvm_LogicalDisk where systemname like '%" . $guid . "%' and name='Hard Disk Image'"); $ct=0; $start1 = microtime(true); $start = microtime(true); foreach($resultDisk as $itemDisk) { $end = microtime(true); echo "<BR>FOREACH: [" . Round($end-$start,3) . "] seconds"; $vm[$name]['disks'][$ct] = ($itemDisk->BlockSize * $itemDisk->NumberOfBlocks)/1024; // format the disk size into KB $ct++; $start = microtime(true); } $end1 = microtime(true); echo "<br> ALLLOOP: [" . Round($end1-$start1,3) . "] "; } catch(exception $e) { } $diskend = microtime(true); echo "<br>DISK: [" . ($diskend-$diskstart) .

So the issue I'm having is consecutive loops on semi-large arrays, over and over. Consider this array:
$firstArray = array(
'row1' => array(
'dates' => array(
'2014-01-01' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'),

Originally the data comes from ~2-3 database tables, of course. But to ilustrate the point, this is how the main array looks like. This array usually contains anywhere between 10-50 rows, each row containing at least 10 dates, with 10 key/values each.
And after setting up all the data, it needs to be processed. Currently this is how a friend of mine did it..
$placeDataHere = array();
foreach($firstArray as $key => $dates) {
foreach($dates as $date => $values) {
foreach($values as $key => $value) {
$placeDataHere['DV_' . $date]['SM_' . $key] = 'KS_' . $value;
//Followed by another ~50-70 lines of processing the 3 loop's data..
...
...
....
....
....
....
....
....
}
}
}
Obviously this isn't good practise, but we can't seem to figure out a better way of doing it, since both the data and the loops are horribly nested.
This loop and setup of $firstArray is run anywhere between 10-20 times/request, due to amount of users we wish to process. So, the result is that this code can take up to over 2-3 minutes to complete, which isn't really optimal performance.
In short my question is, are there any better methods of handling this with the data setup we currently have?
Below is my output on the browser: Student: Kevin Smith (u0867587) Course: INFO101 - Bsc Information Communication Technology Course Mark 70 Grade Year: 3 Module: CHI2550 - Modern Database Applications Module Mark: 41 Mark Percentage: 68 Grade: B Session: AAB Session Mark: 72 Session Weight Contribution 20% Session: AAE Session Mark: 67 Session Weight Contribution 40% Module: CHI2513 - Systems Strategy Module Mark: 31 Mark Percentage: 62 Grade: B Session: AAD Session Mark: 61 Session Weight Contribution 50% Now where it says course mark above it says 70. This is incorrect as it should be 65 (The average between the module marks percentage should be 65 in the example above) but for some stange reason I can get the answer 65. I have a variable called $courseMark and that does the calculation. Now if the $courseMark is echo outside the where loop, then it will equal 65 but if it is put in while loop where I want the variable to be displayed, then it adds up to 70. Why does it do this. Below is the code: Code: [Select] $sessionMark = 0; $sessionWeight = 0; $courseMark = 0; $output = ""; $studentId = false; $courseId = false; $moduleId = false; while ($row = mysql_fetch_array($result)) { $sessionMark += round($row['Mark'] / 100 * $row['SessionWeight']); $sessionWeight += ($row['SessionWeight']); $courseMark = ($sessionMark / $sessionWeight * 100); if($studentId != $row['StudentUsername']) { //Student has changed $studentId = $row['StudentUsername']; $output .= "<p><strong>Student:</strong> {$row['StudentForename']} {$row['StudentSurname']} ({$row['StudentUsername']})\n"; } if($courseId != $row['CourseId']) { //Course has changed $courseId = $row['CourseId']; $output .= "<br><strong>Course:</strong> {$row['CourseId']} - {$row['CourseName']} <strong>Course Mark</strong>" round($courseMark) "<strong>Grade</strong> <br><strong>Year:</strong> {$row['Year']}</p>\n"; } if($moduleId != $row['ModuleId']) { //Module has changed if(isset($sessionsAry)) //Don't run function for first record { //Get output for last module and sessions $output .= outputModule($moduleId, $moduleName, $sessionsAry); } //Reset sessions data array and Set values for new module $sessionsAry = array(); $moduleId = $row['ModuleId']; $moduleName = $row['ModuleName']; } //Add session data to array for current module $sessionsAry[] = array('SessionId'=>$row['SessionId'], 'Mark'=>$row['Mark'], 'SessionWeight'=>$row['SessionWeight']); } //Get output for last module $output .= outputModule($moduleId, $moduleName, $sessionsAry); //Display the output echo $output; I think the problem is that it is outputting the answer of the calculation only for the first session mark. How in the while loop can I do it so it doesn't display it for the first mark only but for all the session marks so that it ends up showing the correct answer 65 and not 72? Hey guys, Got another question im hoping someone can help me with. I have a foreach loop (for use in a mysql query): foreach ($interests as $interest) { $query .= "($id, $interest), "; } problem is i do not want the comma(,) in the last loop. Is there some kinda of function i can use so it does not insert it on last loop? Or should i just use a for loop with a nested if loop? something like ; for($i=0; $i < count($interests); $i++){ $query .= "($id, '$interests[$i]')"; if($i + 1 < count($interests)) { $query .= ", "; } } Cheers guys I am working to echo the results in a while or for loop... Both of my sample codes work, but the results are wrong! The while loop ONLY echos a result IF the first record in the postings table matches the id passed (does not display a result unless the first record has a match) The if loop displays ALL listings with the same name (counts them all) so there are no unique listings! <?php $posts_by_city_sql = "SELECT * FROM postings WHERE id='$_GET[id]'"; $posts_by_city_results = (mysqli_query($cxn, $posts_by_city_sql)) or die("Was not able to grab the Postings!"); /* While Loop */ while($posts_by_city_row = mysqli_fetch_array($posts_by_city_results)) { echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>"; } /* For Loop */ $posts_by_city_row = mysqli_fetch_array($posts_by_city_results); for ($i=0; $i<sizeof($posts_by_city_row); $i++) { echo "<li><a href='posting_details.php?id=$posts_by_city_row[id]'>$posts_by_city_row[title]</a></li>"; } ?> Results with for loop (there are 7 total unique book names, but it's just counting the first match on id 7 times like below): AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners AJAX for Beginners Good Evening - I am in the process of trying to call back a list of categories and sub categories using a WHILE LOOP inside of a WHILE LOOP. It works on a different part of the site within the admin panel but not here. Here it only calls one sub category and moves on to the next parent category instead of finishing the loop and pulling all sub categories out... // CATEGORIES $query = "SELECT * FROM cat"; $result = mysql_query($query); while($row = mysql_fetch_array($result, MYSQL_ASSOC)) { $catid = $row['id']; $catname = $row['name']; $output .= "<li class=\"level0 nav-2 parent\" onmouseover=\"toggleMenu(this,1)\" onmouseout=\"toggleMenu(this,0)\"> <a href=\"product.php?cat=$catid\"> <span>$catname</span> </a>\n"; $querynav = "SELECT * FROM subcat WHERE pid = '$catid'"; $resultnav = mysql_query($querynav); while($array = mysql_fetch_array($resultnav, MYSQL_ASSOC)) { $subcatid = $row['id']; $subcatname = $row['name']; $output .= "<ul class=\"level0\"> <li class=\"level1 nav-2-1 first\"> <a href=\"product.php?cat=$catid&subid=$subcatid\"> <span>$subcatname</span> </a> </li> </ul> </li>"; } } A WHILE loop in a FOR loop problem Script about links and sublinks from 1 table. In fact 2 questions about that. 1) In the FOR loop I have for example to do the loop 3 times. (needs to find 3 results withing the loop with if and else) When first time, he's gonna search within the WHILE loop that holds (for example) 10 records of the DB in a variable. He needs to search for rowid number 5, he found it He goes out of the WHILE loop and goes searching again but now for rowid number 2 Now it seem that the WHILE loop start searching for number 2 but won't start from his first row in the variable (10 rows from the db ). He start at row number 6 instead of beginning all over again !!! -> so the order of the numbers of rows MUST be in an ascending order, ortherwise he won't find them all ! But the numbers I have are NOT in an ascending order !!! Why doesn't the WHILE loop begin again from his row 1 in the variable ? FOR loop { WHILE loop { content here, break; } } 2) even when I get all the result in an ascending order, he won't go doing a second search but with a different rowid number that he gets from the FOR loop. It is giving me back indeed the right new rowid number, but the WHILE loop is doing nothing. I have put many echo "..."; and other stuff for checking but can't find the cause ! Here's the code : Code: [Select] // $ResultShow = 10 rows from mysql db if(isset($ResultShow)){ if (mysql_num_rows($ResultShow) >= 1){ //$linksuborder = "2,3,4"; $array1 = explode(",", $linksuborder); sort($array1); for ($n = 0; $n < count($array1); $n++){ // searchin for the right row id in the variable $ResultShow where we find the numbers for next loop $r1 = each($array1); While($Row2 = mysql_fetch_array($ResultShow)) { if($Row2["linkid"] == $r1['value']) // found it, now look for the numbers that we'll put in an array { echo "---here the content---"; // linksuborder is where numbers from row id's are stored like 5,2,8 //now put them in an array $array2 = explode(",", $Row2["linksuborder"]); sort($array2); for ($n2 = 0; $n2 < count($array2); $n2++){ $r2 = each($array2); ////// here searching for the sublinks ////// While ($Row3 = mysql_fetch_array($ResultShow)) { if($Row3["linkid"] == $r2['value']) // search for the right row id within the variable $ResultShow { echo "---here the content---"; break; // found it, so no need to do the rest of the loop } // end if } //end while ////// end searching for sublinks ////// } // end for } // end if else { echo "--- content here ---"; } } // end while } // end for } //end if } // end if Table : linkid linksuborder linktitle 1 2,3,4 2 9,7,8 mainlink1 3 10 mainlink2 4 mainlink3 5 6 7 sublink3 8 sublink2 9 sublink1 10 sublink4 -> linksuborder 2,3,4 are the row id's for the mainlink -> than we put the numbers 9,8,7 (also row id's) mentioned in row linkid 2 also in a new array -> now we can search for the sublinks -> get the details from row linkid 9, than 7, than 8 -> First mainlink is compleet, now go to row linkid 3 to do it all over again for the next mainlink... RESULTS from an sorted array -> sort($linksuborder); ------------------------------------------------------------- mainlink1 : sublink1, sublink2, sublink3 mainlink2 : **no result back but it should * mainlink 3 : **no result back but it should * Hi, I am new to PHP. Can someone explain me clearly how to use while loop inside while loop to print "*" in square shape. Thank you for your help. So I have a PHP parent page that is accesses that scans the database for the passed token in the URL and then replaces content on the template page using a loop. My issue is that I am trying to use a loop on the secondary page which causes the white screen of death. From what I can tell the loop inside a loop is causing the issue. I'll paste the code below, let a newbie know if you have any ideas or can point me in the right direction. Thanks everyone! Here is the chunk of code from the parent page with the loop function.... // output pre content eval("\$preContent = \"$preContent\";"); print_r( replaceChar($preContent) ); $sqlSearch = "SELECT * FROM ".$row[tdbd_name]." WHERE ".$sqlKeyword." LIMIT ".MAX_ROWS; $resultSearch = mysql_query($sqlSearch); while($displayrows = mysql_fetch_assoc($resultSearch)) { $display = replaceTokens($loopTemplate); $display = str_replace('\\', '[backslash]', $display); $display = str_replace('[%', '$displayrows[', $display); $display = addslashes(str_replace('%]', ']', $display)); $display = replaceTokens($display); $display = changeCase($display); eval("\$display = \"$display\";"); $display = stripslashes($display); $display = str_replace('[backslash]', '\\', $display); $display = replaceChar($display); print_r( $display ); } // output post content And here is the loop function from the page that the above code loops through replacing tokens in. <?php $mySQLServer = "xxxxxxxxx"; $mySQLUser = "xxxxxxxxxx"; $mySQLPass = "xxxxxxxx"; $mySQLDB = "xxxxxxxxxxxxx"; $SQLToday = date("m/d/y") .
