note 53952 added to control-structures.foreach

On the note of Paul's for loop: function foo($x) { global $arr; // some Array for($i=0; $i < count($arr); $i++) { if($arr[$i][0] == $x) { echo $arr[$i][1]."\n"; foo($arr[$i][0]); } } } ------------ The middle part of the for loop is evaluated every time it loops which means the count function is called as many times as it loops. It's always better (performance/speed wise) to put the count as the initialization code: function foo($x) { global $arr; // some Array for($i=count($arr)-1;; $i>=0; $i++) { if($arr[$i][0] == $x) { echo $arr[$i][1]."\n"; foo($arr[$i][0]); } } } ---- Manual Page -- http://www.php.net/manual/en/control-structures.foreach.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+53952 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+53952&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+53952&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+53952&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+53952&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+53952&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+53952&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+53952&report=yes Search -- http://master.php.net/manage/user-notes.php
