I had the same problem with foreach() and a recursiv function. If you don't want to spend about 1 or 2 hours to solve this problem, just use for() loops instead of foreach(). Some Example: $arr[] = array(1,"item1"); $arr[] = array(2,"item2"); $arr[] = array(1,"item3"); //$arr[] = ... //doesn't work function foo($x) { global $arr; // some Array foreach($arr as $value) { if($value[0] == $x) { echo $value[1]."\n"; foo($value[0]); } } } //just use this 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]); } } } Paul ---- Manual Page -- http://www.php.net/manual/en/control-structures.foreach.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52892 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52892&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52892&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52892&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52892&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52892&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52892&report=yes Search -- http://master.php.net/manage/user-notes.php
