note 54311 added to control-structures.foreach

Benchmarking tool I used: http://phplens.com/phpeverywhere/phpe-2004.htm#a3297 http://phplens.com/lens/dl/JPBS.zip <?php // -------------------------------------------------------------------- foreach ( array_keys($myArray) as $key ) { $element =& $myArray[$key]; ... } // -------------------------------------------------------------------- foreach( $myArray as $key => $element ) { $element =& $myArray[$key]; ... unset($element); } // -------------------------------------------------------------------- reset($myArray); while ( list($key) = each($myArray) ) { $element =& $myArray[$key]; ... unset($element); } ?> Andrew ---- Manual Page -- http://www.php.net/manual/en/control-structures.foreach.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54311 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54311&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54311&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54311&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54311&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54311&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54311&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54311&report=yes Search -- http://master.php.net/manage/user-notes.php
