It would work if PHP had a method for determining if two variables are the same reference. (unless there is one that I haven't found...) <?php $a=array(1,2,3); $a[3]=&$a; $a=array_recurse_safe($a); array_merge_recursive($a,$a); var_dump($a); function array_recurse_safe($array, $parents=array()) { $parents[]=&$array; foreach($array as $element) { if(is_array($element) || is_object($element)) { $loop=false; foreach($parents as $parent) { if(&$parent == &$element) { unset($element); $loop=true; } } if(!$loop) { $element=array_recurse_safe($element, $parents); } } } return $array; } ?> Also, the usage of unset() is improper here, but I left it in for simplicity. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=17279&edit=1
