note 16150 added to control-structures.for

You should always cast the looping index to an int if you're initializing it with another variable. Otherwise you risk getting caught in an infinite loop. The following will run till Kingdom comes: function a($start_index) { for($i = $start_index; $i < 10; $i++) echo "\$i = $i\n"; } a('Eternity!'); More subtle is a(false), which also loops forever. -- http://www.php.net/manual/en/control-structures.for.php http://master.php.net/manage/user-notes.php?action=edit+16150 http://master.php.net/manage/user-notes.php?action=delete+16150 http://master.php.net/manage/user-notes.php?action=reject+16150
