This bug has been fixed in CVS. 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/. Thank you for the report, and for helping us make PHP better. This seems to be a duplicate of bug #48522, which is now fixed in CVS. I now get the following result with your original code. 0.000047 0.000079 Previous Comments: ------------------------------------------------------------------------ [2009-02-04 13:47:36] php at wallbash dot com Hi, i hope i don't bug you but do you know when this might get fixed or is there a patch available ? We (finally) moved to 5.2 and this is a showstopper for us and would (sadly) require lots of refactoring. Thanks ------------------------------------------------------------------------ [2008-07-01 21:30:28] der...@php.net I'll have a look at this, but there is even a MUCH faster way: <?php $d = new DateTime( '1902-03-25 18:25:25' ); $mt0 = microtime(true); $d->modify( '+1 year' ); $mt1 = microtime(true); $d->modify( '+1 year' ); $mt2 = microtime(true); printf("%.6f\r\n%.6f\r\n", $mt1-$mt0, $mt2-$mt1); ?> 0.013312/0.696215 for your code, vs 0.000065/0.000028 for my approach. ------------------------------------------------------------------------ [2008-07-01 20:55:08] jerico dot dev at gmail dot com Description: ------------ strtotime() performs 3 orders of magnitude slower when operating on a timestamp. Reproduce code: --------------- $string = '1902-03-25 18:25:25'; $timestamp = strtotime($string); $mt0 = microtime(true); $result1 = strtotime("$string +1 year"); $mt1 = microtime(true); $result2 = strtotime("+1 year", $timestamp); $mt2 = microtime(true); printf("%.6f\r\n%.6f\r\n", $mt1-$mt0, $mt2-$mt1); // This will output // 0.000171 // 0.721877 // on my machine Actual result: -------------- see reproduce code ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=45409&edit=1
