PHP - Where's The Endless Loop Here?
The function here is supposed to catalog the files in a given folder, and all subfolders, and report back the filenames to the screen as links to themselves. Despite my best amateur efforts, I can't get away from the endless loop errors.
Code: [Select] function explore($dir, $filePath) { $blah = opendir($dir); while (false !== ($file = readdir($blah))) {if (is_dir($file)) { $filePath = $filePath.$file.'\\'; closedir($blah); explore($file, $filePath);} else { $filePath = $filePath.$file; echo "<a href='$filePath'>'$file'</a>"; echo "<br />";} $fLength = strlen($file); $fpLength = strlen($filePath); $filePath = substr($filePath, 0, ($fpLength -$fLength)); } } Similar Tutorialsthis is only returning one record, when I know there are more, and it's an endless loop crashing my browser, can someone tell me how my brackets are wrong, or what is wrong? Code: [Select] if (isset($_POST['search'])){ $keyword=$_POST['keyword']; } $sql="SELECT id, fname, lname FROM obituaries WHERE lname LIKE '%$keyword%' OR fname LIKE '%$keyword%' ORDER BY id DESC"; $results = mysql_query($sql); $num = mysql_num_rows ($results); if ($num > 0 ) { $i=0; while ($i < $num) { $id = mysql_result($results,$i,"id"); $fname = mysql_result($results,$i,"fname"); $lname = mysql_result($results,$i,"lname"); ?> <a href="view.php?id=<?php echo ($id); ?>"><?php echo($fname); ?> <?php echo($lname); ?></a> <?php } } ?>Thanks in advance Hi all, I have a site where the user must register to buy some products. After registration, you login and with the help of SESSIONS, you can view the page buynow.php. After the weekend, I opened the page and I got some yummy errors... Fatal error: Call to undefined function stop() in /home/pharmacz/public_html/ads/main_login.php on line 6 And line 6 reads: YES, BLANK...

The register.php work fine Any Idea?? Hey.
So the issue I'm having is consecutive loops on semi-large arrays, over and over. Consider this array:
$firstArray = array(

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.

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>"; } } I'm having a really bad brain fart and I cannot get the logic correct here lol. I need divs wrapped around every set of 5 images so if there is a total of 8 images then there would be 2 sets of divs (first with 5 images, second with 3 images) and if there was 12 images then there would be 3 sets of divs (first two with five images, last one with 2 images) etc etc What am I doing wrong and is there an easier way to do this? http://pastebin.com/QfsFxe4G Thanks!

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!

Thank you I hope somebody can help me.. 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 * Alright heres the scripts... $query = "SELECT Game_ID, Pick FROM Cfb WHERE User_ID= 1"; $result = mysql_query($query); $query1 = "SELECT Game_ID, Pick FROM Cfb WHERE User_ID= 61"; $result1 = mysql_query($query1); $affected = mysql_num_rows($result); for($i=0; $i< $affected; $i++) { $scores =mysql_fetch_assoc($result); $scores1 =mysql_fetch_assoc($result1); $final = array_diff_assoc($scores,$scores); $user = array_diff_assoc($scores, $scores1); $f = count($final); $u = count($user); if ($f == $u){ $points = +1; }else{ $points = +0; } echo $points; echo '<br />'; echo '<hr>'; } The script pulls information out of the mysql table and compares it to each users input. Then it either gives the user a point or not! I need someway to add up all the $points values. to decide how many points that they get. (Currently for testing purposes i have put 12 rows of data in my table for a user and for what it is compared to.) (So 24 rows total) Eventually this will all go into a function and User_ID at the top will be set to a variable and the script will run for all the users not just user id 61! my table is set up like this (Ignore "Week" for now) +---+----------+------------+-------+------+ | ID | User_ID | Game_ID | Week | Pick | +---+----------+------------+-------+------+ ID is auto incrementing and the rest is pretty self explanatory Hi, I am trying to create a loop as such so that when I load the script it will check for the date in the 'start_date' field, normally formatted by the date(Y-M-D) function, but I need it to loop until the end of the current year and insert data too.

QUERY RESULTS WITH LIMIT TOP 6: selected_team|selected_score|week|year|home_id|target_score|targetname|ID Xanadu Dragons|397.4|Week 9|2010|12|394.7|America Enforcers|9 Xanadu Dragons|357.4|Round 1|2010|1|361.6|America Enforcers|22 Xanadu Dragons|416.6|Week 2|2011|12|369.8|America Enforcers|2 Xanadu Dragons|417.0|Week 5|2010|11|301.9|Battle Masters|5 Xanadu Dragons|360.8|Week 4|2011|11|459.1|Battle Masters|4 Xanadu Dragons|99.0|Week 1|2006|1|93.0|Camelot Fluffy Butts|1 So the problem must be when I put the query results into the php code below: Code: [Select] $wins=0; $losses=0; $draws=0; $last_target = false; echo '<h3>' . $row['selected_team'] . '</h3>'; while ($row = mysql_fetch_assoc($result)) { if ($last_target['targetname'] != $row['targetname']) { if ($last_target) { printf(' <table class="style1" border="1" width="400"> <tr> <th>Opponent Name:</th> <th colspan="2">%s</th> </tr> <tr> <th>Wins</th> <th>Losses</th> <th>Draws</th> </tr> <tr> <td align="center">%d</td> <td align="center">%d</td> <td align="center">%d</td> </tr> <tr> <th>Last Game:</th> <td colspan="2">%s of %s: %.1f - %.1f</td> <tr> </table><br/>', $last_target['targetname'], $wins, $losses, $draws, $last_target['week'], $last_target['year'], $last_target['selected_score'], $last_target['target_score'] ); } $wins = $losses = $draws = 0; } if ($row['selected_score'] < $row['target_score']) ++$losses; elseif ($row['selected_score'] == $row['target_score']) ++$draws; else ++$wins; $last_target = $row; } if ($last_target) { } ?> The display however gives me the following: Opponent Name: America Enforcers Wins Losses Draws 1 1 0 Last Game: Week 2 of 2011: 416.6 - 369.8 as you can see from the above database results this team played the America Enforcers 3 times, however the php code only displays 2 games. All other match ups are correct, it is just this first row. Any ideas? Please and thank you for your time and effort. I have this script that asks the user their name and email address and age and stuff and it checks to see what their age is and outputs a message depending on what age bracket they belong to. I am trying to make a for loop that uses the value the user submitted for their age and output the range of numbers from the users age to 1000 by 3s, i know how the basic for loop works, but i don't know how to do one where you are using a variable for i. if that makes sense. Heres the code that i have. test1.html Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>Feedback Form</title> </head> <body> <div><p>Please complete this form to submit your feedback:</p> <form action="test1.php" method="post"> <p>Name: <select name="title"> <option value="Mr.">Mr.</option> <option value="Mrs.">Mrs.</option> <option value="Ms.">Ms.</option> </select> <input type="text" name="name" size="20" /></p> <p>Email Address: <input type="text" name="email" size="20" /></p> <p>Age: <input type="text" name="age" size="20" /></p> <p>Response: This is... <input type="radio" name="response" value="excellent" /> excellent <input type="radio" name="response" value="okay" /> okay <input type="radio" name="response" value="boring" /> boring</p> <p>Comments: <textarea name="comments" rows="3" cols="30"></textarea></p> <input type="submit" name="submit" value="Send My Feedback" /> </form> </div> </body> </html> test1.php Code: [Select] <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>Your Feedback</title> </head> <body> <?php include('test1.html'); $name = $_POST['name']; $age = $_POST['age']; $okay = TRUE; if(empty($name)){ echo '<p class="error"> Please enter your name.</p>'; $okay = FALSE; } if (empty($age)){ echo '<p class="error"> Please enter you age.</p>'; $okay = FALSE; } if ($age < 65){ echo '<p>no retirement for you</p>'; } if ($age == 65){ echo '<p> Yay, you can retire</p>'; } if ($age > 65 || $age < 100){ echo '<p>Florida is for me!</p>'; } if ($age > 100){ echo '<p>Good Genes</p>'; } //print users age to 1000 by 3s for($i=$age; $<1000 i+3){ echo '$age'; } ?> </body> </html> Hello. I have a simple SQL query that returns a list of names, this is good and all is right with the world. I would like to associate a number with each person, a RANDOM number that will change each time I call the page. Desired result:
Number | Name
18 | Jeff
2 | Tammy
12 | Steve
10 | Phil
5 | Michelle
etc. etc.
Pool of numbers will be from 1 to 30. Sometimes the names pool will result in 18 rows or 27 rows or any number in between. I just need to assign a number from 1 to 30 to each name that is not the same each time. Here's my loop.
while ($row= mysql_fetch_array($result)) {
$lastname = $row["lastname"];
$firstname = $row["firstname"];
$numbers = range(1, 30);
shuffle($numbers);
foreach ($numbers as $number) {
}
echo "<tr>
<td class='results'>$number</td>
<td class='results'>$firstname $lastname</td>
</tr>";
}
Here's the problem I'm encountering:
1) If I leave the FOREACH inside the loop, I wind up with one or two repeated $number(s).
2) If I take the FOREACH outside the loop, I wind up with the first integer from the $numbers range repeated as many times as there are names
I'm just not sure how to achieve a unique designation for each name.
Could someone point me in the right direction? Thanks so much!
I need to pull information from a db table for a slideshow on my page, and need a little help. All of the {$image}'s need to be pulled out and displayed in a div#slider first, then if $caption is set to 1, the caption info is displayed in a div#htmlcaption after the images div#slider. I have an example of the divs below the mysql query, but I'm not sure how to insert it into the while loop. TIA Code: [Select] <?php $sql = mysql_query("SELECT * FROM slideshow"); if(mysql_num_rows($sql) > 0) { while($row = mysql_fetch_assoc($sql)) { $slideID = $row['slideID']; $image = $row['image']; $caption = $row['caption']; $caption_h3 = $row['caption_h3']; $caption_content = $row['caption_content']; $caption_link = $row['caption_link']; $caption_link_text = $row['caption_link_text']; } } ?> Code: [Select] <div id="slider"> <img src="{$image}" alt="" title="#htmlcaption{$slideID}" /> <img src="{$image}" alt="" title="#htmlcaption{$slideID}" /> <img src="{$image}" alt="" title="#htmlcaption{$slideID}" /> </div> <div id="htmlcaption{$slideID}" class="nivo-html-caption"> <h3>$caption_h3</h3> <p>$caption_content</p> if($caption_link != '') { <p><a href="{$caption_link}">{$caption_link_text}</a></p> } </div> |
