In case this was a PHP problem, snapshots of the sources are packaged every three hours; this change will be in the next snapshot. You can grab the snapshot at http://snaps.php.net/. In case this was a documentation problem, the fix will show up soon at http://www.php.net/manual/. In case this was a PHP.net website problem, the change will show up on the PHP.net site and on the mirror sites in short time. Thank you for the report, and for helping us make PHP better. Thanks for testing this; one line of the old code was accidentally left in the 4.3 branch; human error (mine). I've tested this using PHP 4.3; benchmarked at 4 seconds (using same script and file as mentioned previously). The next snapshot will have the fix. ------------------------------------------------------------------------ [2003-03-18 19:14:00] shawn at rumental dot com latest win32 Stable (4.3.x-dev) Built On: Mar 18, 2003 17:30 GMT http://snaps.php.net/win32/php4-win32-STABLE-200303181730.zip still yields the same results as before. no change although Latest CVS (5.0.x-dev) is fast as shit. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
