#41364 [Bgs]: Auto increment problem

ID: 41364 User updated by: wimroffel at planet dot nl Reported By: wimroffel at planet dot nl Status: Bogus Bug Type: Unknown/Other Function Operating System: Windows XP PHP Version: 5.2.2 New Comment: That sounds like a very weak excuse to change the working of the language and causing me and probably many others many hours of debugging. Previous Comments: ------------------------------------------------------------------------ [2007-05-11 13:14:01] tony2001@php.net This behaviour is undefined in all languages including PHP. ------------------------------------------------------------------------ [2007-05-11 13:11:44] wimroffel at planet dot nl 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 this bug report at http://bugs.php.net/?id=41364&edit=1
