Doc #54456 [NEW]: date_modify's $modify argument differs from the strtotime's $time argument

From: Operating system: Windows 7 PHP version: 5.2.17 Package: Documentation problem Bug Type: Documentation Problem Bug description:date_modify's $modify argument differs from the strtotime's $time argument Description: ------------ --- From manual page: http://www.php.net/datetime.modify --- Documentation implicitly says that $modify argument of the date_modify function is equal in its meaning to the $time argument of the strtotime function, however they differ. date_modify ignores the time value specified (please see the code snippet below). Test script: --------------- <?php $time = 'next Monday 19:00'; $d = new DateTime('now'); $d->modify($time); echo $d->format('Y-m-d H:i:s') . "\n"; $t = strtotime($time); $d = new DateTime('@'.$t); echo $d->format('Y-m-d H:i:s') . "\n"; ?> Expected result: ---------------- 2011-04-04 13:00:00 2011-04-04 13:00:00 Actual result: -------------- 2011-04-04 08:55:37 2011-04-04 13:00:00 -- Edit bug report at http://bugs.php.net/bug.php?id=54456&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=54456&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=54456&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=54456&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=54456&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=54456&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=54456&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=54456&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=54456&r=needscript Try newer version: http://bugs.php.net/fix.php?id=54456&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=54456&r=support Expected behavior: http://bugs.php.net/fix.php?id=54456&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=54456&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=54456&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=54456&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=54456&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=54456&r=dst IIS Stability: http://bugs.php.net/fix.php?id=54456&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=54456&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=54456&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=54456&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=54456&r=mysqlcfg
