#23654 [Asn]: for nested arryas, str_replace return wrong value

ID: 23654 Updated by: andrey@php.net Reported By: marcel_preda at yahoo dot com Status: Assigned Bug Type: Scripting Engine problem Operating System: any PHP Version: 4.3.1 -Assigned To: andrey +Assigned To: pollita New Comment: Pollita is keen on str_replace() :) Previous Comments: ------------------------------------------------------------------------ [2003-05-16 02:36:50] moriyoshi@php.net assigning to andrey ------------------------------------------------------------------------ [2003-05-16 02:13:20] marcel_preda at yahoo dot com I suppose that the problem is in ALL PHP versions. from PHP manual: --- mixed str_replace ( mixed search, mixed replace, mixed subject [, int &count]) --- If `subject' is a nested array the return is strange (at least unexpected) For example, next pice of code: <?php $x = array ( 'abc', 'xayz', array('ddddadddd ', ' fffffffffff ' ) ); $y=str_replace('a','A',$x); print_r($y); ?> I'm expecting as output: Array ( [0] => Abc [1] => xAyz [2] => Array ( [0] => ddddAdddd [1] => fffffffffff ) ) But, the output is: Array ( [0] => Abc [1] => xAyz [2] => ArrAy ) I thnik that str_replace should do a recursive call, with type checking. For now I've solve the problem in my own way: // for nested arrays as `subject' looks like str_replace has wrong return function my_str_replace($search, $replace, $mixed) { if (is_string($mixed)) return str_replace($search, $replace, $mixed ); if(is_array($mixed)) { foreach($mixed AS $key=>$value) $mixed[$key] = my_str_replace($search, $replace, $value); return $mixed; }; // non interesting types return $mixed; } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=23654&edit=1
