PHP - Inverse Of Do-while Loop?
Is there any way to invert a Do-While loop so it continues to loop through the Do statement if the While statement is FALSE. And then end execution once the While statement is true.
Code: [Select] do{ $length = 2; $characters = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"; $string =""; $string.= microtime(true); for ($p = 0; $p < $length; $p++) { $string .= $characters[mt_rand(0, strlen($characters))]; } $string= substr_replace($string, '', 0, 4); for ($p = 0; $p < $length; $p++) { $string2 .= $characters[mt_rand(0, strlen($characters))]; } $string="".$string2."".$string; $string=explode(".",$string); $string=$string[0].$string[1]; $rma_number=$string; $sql12345="SELECT * FROM $tbl_name4 WHERE rma_number=$rma_number"; $result12345=mysql_query($sql12345); $num_rows12345=mysql_num_rows($result12345); } while($num_rows12345 < 1){ $sql2000000="UPDATE $tbl_name4 SET rma_number='$rma_number', rma_name='$rma_name' WHERE rma_id = $rma_id"; mysql_query($sql2000000); } Similar TutorialsHello,
Is anybody aware of a statistical function in PHP which returns the inverse of the normal cumulative distribution, given a probability, mean and standard deviation as inputs? Thank you. Hey.
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'), '2014-01-02' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-01-03' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-01-04' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-01-05' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-01-06' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-01-07' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), ) ), 'row2' => array( 'dates' => array( '2014-02-01' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-02' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-03' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-04' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-05' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-06' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-07' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-08' => array('key1' => 'value1', 'key2' => 'value2', 'key3' => 'value3', 'key4' => 'value4', 'key5' => 'value5', 'key6' => 'value6', 'key7' => 'value7', 'key8' => 'value8', 'key9' => 'value9', 'key10' => 'value10'), '2014-02-09' => 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>"; } } 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.

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...

The mysql table has 11 entries and one of them is about to expire so the user should be sent an email but the code above doesn't work. Does anyone see anything wrong with the code above?

"% Campaign progress"; $progress6->width = 800; $progress6->height = 22; $progress6->style = "image"; $progress6->makeBar(); } mysql_close(); im using faction to show progress bar for record can sombady help me how to loop this for all records? Hey guys, I got some questions about the while loop It's dealing with the "qset" as you can see below: Code: [Select] $get = "SELECT qset from mailing_list where email = '$email'"; $result = mysqli_query($connect, $get) or die($connect); while ($row = mysqli_fetch_array($result)){ extract($row); $qset = rsort($row); $qset = (int)end($row); } if (empty($qset) || $qset < 1){ $qset = 1; return $qset; } elseif ($qset >=1){ $qset = $qset + 1; return $qset; } echo $qset; Nothing echoed out... Why? Also it seems like the script got stuck at the while loop, as no sql commands that follow up are processed Any help is appreciated! Thanks I have a MySQL query that works, as it displays the results I want in the database, however when I put that query into some php code it ignores the first row and I was wondering if someone could point out what I am doing wrong. This is for a fantasy football league. You choose your team name from a drop down list and hit submit. It is then supposed to produce a list of your choosen teams performance against all other active teams AND the results of the last game played. QUERY: Code: [Select] <?php //the connection information is located in a function include_once('call function'); $con = mysql_connect($hostname, $username, $password) OR DIE ('Unable to connect to database! Please try again later.'); $db = mysql_select_db($dbname, $con); $thing = $_GET['thing']; $query = "select selected.teamname AS selected_team, selected_score.score AS selected_score, week.week, year, home_id, ". "target_score.score as target_score, target.teamname as targetname, week.ID ". "from owners as selected ". "JOIN game_scores AS selected_score ON selected.owner_id = selected_score.team_id ". "JOIN game_setup ON game_setup.game_id = selected_score.game_id ". "JOIN game_scores AS target_score ON target_score.game_id = game_setup.game_id AND target_score.team_id != ". "selected_score.team_id ". "JOIN owners AS target ON target.owner_id = target_score.team_id ". "JOIN week ON week.week = game_setup.week ". "WHERE selected.owner_id = $thing ". "and target.active = 1 ". "GROUP BY target.teamname, year, week.ID "; $result = mysql_query($query); $row = mysql_fetch_array($result); if (!$result) { die('Invalid query: ' . mysql_error()); } Now I know the query produces the correct results as I have run it many times in my database software and it always gives me all the rows. 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 want to control the output of php code with if else statement like this. <?php if($row_director['director'] == "") {echo "";} else {echo " <table> <th> <h4>Directed by</h4> </th> <td> <h5> $row_director['director'] </h5> <br /> </td> </table> <br /> ";}?> I also want to loop through the results contained in $row_director['director'] Having tried various ways to achieve this, I have now given up. Can someone please help me. |
