Say, array_flatten ($array) or something? ------------------------------------------------------------------------ [2005-03-04 19:08:43] bolk at hitv dot ru I see that the zend_print_zval_r_ex() detects recursive references. ------------------------------------------------------------------------ [2005-03-04 19:01:30] bolk at hitv dot ru I belive this situation must be detected. I think it is a bug. preg_grep() should not change its agruments. ------------------------------------------------------------------------ [2005-03-04 18:56:19] tony2001@php.net bolk: yup, this is the very same behaviour. all elements of the target array get converted to strings, that's what you see. plintus: propose your own solution instead of useless comments? recursive references should be carefully used and current situation looks like a user fault to me. ------------------------------------------------------------------------ [2005-03-04 18:37:12] plintus at smtp dot ru Tony, if a bug occurs in some other situations, it's still a bug. However, Microsoft can use this trick: "Bugs are expected behaviour in Windows" :-) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
