Duplicate of bug #47643. Previous Comments: ------------------------------------------------------------------------ [2009-09-01 00:04:33] fel...@php.net See bug #47643 ------------------------------------------------------------------------ [2009-08-31 16:42:06] sjo...@php.net Could reproduce. This code shows the time taken to array_diff two arrays for the builtin array_diff and for a PHP function fast_array_diff I wrote. <?php $a = $b = array(); for ($i = 0; $i < 10000; $i++) { $a[] = "s" . ($i * 102121 % 433061); $b[] = "s" . ($i * 102121 % 433003); } $start = microtime(true); $res1 = array_diff($a, $b); echo "Built-in array_diff duration: ".(microtime(true) - $start)."\n"; include('http://www.gissen.nl/files/fast_array_diff.php'); $start = microtime(true); $res2 = fast_array_diff($a, $b); echo "Fast_array_diff duration: ".(microtime(true) - $start)."\n"; sort($res1); sort($res2); assert($res1 == $res2); ?> Output: Built-in array_diff duration: 11.8710849285 Fast_array_diff duration: 0.254959106445 ------------------------------------------------------------------------ [2009-02-08 13:03:18] j...@php.net Please don't send me more spam. (never saw that and any direct mails to me will be deleted anyway) ------------------------------------------------------------------------ [2009-01-27 13:55:35] sgnutzmann at yahoo dot de I just try the latest version 'php-5.2-win32-VC6-x86-latest.msi' (2009-Jan-27 12:00:00). This version has the same problem as PHP 5.2.8 (no return in 5 minutes from array_diff(), infinite loop?). I sent my test dataset 'TestData.txt' to j...@php.net. ------------------------------------------------------------------------ [2009-01-27 12:09:33] sgnutzmann at yahoo dot de PHP 5.2.6 has the same problem as PHP 5.2.8 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
