Previous Comments: ------------------------------------------------------------------------ [2002-04-09 17:00:00] jimw@php.net the code below works fine for me. please provide a complete example of code that fails. function funcB($arr) { return 'whatever'; } function funcA($arr) { $someotherhaystack = '%value1% foo %value2%'; $t = preg_replace_callback("/%value([0-9]+)%/", "funcB", $someotherhaystack); return $t; // $t still makes sense here } $haystack = '%text12% bar %text13%'; echo preg_replace_callback("/%text([0-9]+)%/", "funcA", $haystack); ------------------------------------------------------------------------ [2002-03-13 07:31:50] markus.pfefferle@web.de A preg_replace_callback() that calls a callback function which in turn makes use of a preg_replace_callback() function too, will not work correctly. The first preg_replace_callback() will substitute gibberisch even though the callback function returned a valid string. Example: function funcB($arr) { ... return $whatever; } function funcA($arr) { ... $t = preg_replace_callback("/%value([0-9]+)%/", "funcB", $someotherhaystack) return $t; // $t still makes sense here } echo preg_replace_callback("/%text([0-9]+)%/", "funcA", $haystack); // but whatever funcA returned, just some gibberisch is substituted for /%text[0-9]+%/ ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16040&edit=1
