#41364 [NEW]: Auto increment problem

From: wimroffel at planet dot nl Operating system: Windows XP PHP version: 5.2.2 PHP Bug Type: Unknown/Other Function Bug description: Auto increment problem Description: ------------ When I have a loop for($i=0; $i<$size;) { $myarr[$i][3] = $i++; } PHP will first take the assigned value, then increase $i and that use the new $i to set the array. So the first loop will do: $myarr[1][3]=0; I come from PHP4 and there this worked correctly (first line $myarr[0][3]=0;). I am using XAMPP and as a consequence PHP 5.2.1. But I couldn't find this in the bug database so I suppose it has not been solved. Reproduce code: --------------- $myarr = array(); $myarr[0] = array("A","B","C"); $myarr[1] = array("D","E","F"); $myarr[2] = array("G","H","I"); $size = sizeof($myarr); echo "The size of myarr is ".$size."<br>"; for($i=0; $i<$size;) { $myarr[$i][3] = $i++; } for($i=0; $i<$size; $i++) { echo "Record ".$i." = ".$myarr[$i][3]."<br>"; } echo "The size of the array is now ".sizeof($myarr); Expected result: ---------------- The size of myarr is 3 Record 0 = 0 Record 1 = 1 Record 2 = 2 The size of the array is now 3 Actual result: -------------- The size of myarr is 3 Record 0 = Record 1 = 0 Record 2 = 1 The size of the array is now 4 -- Edit bug report at http://bugs.php.net/?id=41364&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=41364&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=41364&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=41364&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=41364&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=41364&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=41364&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=41364&r=needscript Try newer version: http://bugs.php.net/fix.php?id=41364&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=41364&r=support Expected behavior: http://bugs.php.net/fix.php?id=41364&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=41364&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=41364&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=41364&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=41364&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=41364&r=dst IIS Stability: http://bugs.php.net/fix.php?id=41364&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=41364&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=41364&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=41364&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=41364&r=mysqlcfg
