I think it is to do with using parentheses directly next to each other. Reproduce code: --------------- <? $str = 'arr[sub][sub_sub]'; die(preg_replace('/([^\[\]]*)(.*)/','[\1]\2',$str)); ?> just for the record, this works as expected if i use the pattern: preg_replace('/([^\[\]]*)\[(.*)\]/','[\1][\2]',$el); so it appears that the problem is when parenthesised (is that correct?) expression appear next to each other. Expected result: ---------------- [arr][sub][sub_sub] Actual result: -------------- [arr][sub][sub_sub][] ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=37600&edit=1
