#32192 [Opn]: preg_grep & GLOBALS

ID: 32192 User updated by: bolk at hitv dot ru Reported By: bolk at hitv dot ru Status: Open Bug Type: PCRE related Operating System: Linux RH 9 and Windows XP PHP Version: 5.0.3 New Comment: Why not introduce a function that converts refs to non-refs in array? Say, array_flatten ($array) or something? Previous Comments: ------------------------------------------------------------------------ [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" :-) ------------------------------------------------------------------------ [2005-03-04 18:36:12] bolk at hitv dot ru Is it "expected behaviour" too? I think no. <? $b = array(1,2,3); $a = array(); $a[] = &$b; preg_grep('/^T_/', $a); var_dump($a); var_dump($b); ?> array(1) { [0]=> &string(5) "Array" } string(5) "Array" ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
