#18773 [Ctl]: Quicksort result is different between Windows and Unix.

ID: 18773 Updated by: zeev@php.net Reported By: rgaidot@swt.fr Status: Critical Bug Type: Arrays related Operating System: Windows 2000 Pro PHP Version: 4CVS-2002-08-07 New Comment: Reduced to: <?php print_r(array('0D2', '004')); ?> Further details soon... Previous Comments: ------------------------------------------------------------------------ [2002-08-08 08:31:26] kalowsky@php.net I'd like to mark this as critical because my local tests show: MacOSX results: Sort 1 Sort 2 1 5 2 3 3 4 4 2 5 1 Win2000 results: Sort 1 Sort 2 1 1 2 3 3 4 4 5 5 2 Neither sort went over correctly. ------------------------------------------------------------------------ [2002-08-07 05:02:12] eru@php.net reclassified, updated version, verified ------------------------------------------------------------------------ [2002-08-07 04:46:18] rgaidot@swt.fr I have tried to use the sort function on a string array. The array strings include both integer and char characters. (e.g. 0000AER, 000000S0, 00000073) I have noted that the result differs between the two systems Windows and Unix. Indeed the result on Unix is correct, but it is not correct on Windows. I have made a C++ test application in order to compare the results between the two systems and I did not note any problem. <PHPScript_Test> $a=array( array('000000S0','1','5'), array('000000O2','2','4'), array('000000D2','3','3'), array('000000MH','4','2'), array('00000073','5','1') ); echo "<h1>Data</h1>"; echo "<pre>"; var_dump($a); echo "</pre>"; sort($a); echo "<h1>Result</h1>"; echo "<pre>"; var_dump($a); echo "</pre>"; </PHPScript_Test> Thanks, Régis Gaidot ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=18773&edit=1
