From: whitephoenix at mail dot ru Operating system: tested on WinXP PHP version: 5.1.4 PHP Bug Type: *General Issues Bug description: Lambda unexpected string Description: ------------ Its seems, PHP should show error with type E_WARNING. If it's wrong, then i think, NUL-byte is unexpected there. Reproduce code: --------------- <?php // ASCII in hex function show_callback($m) {return '['.dechex(ord($m[0])).']';} function show($result) {echo preg_replace_callback('~\W~','show_callback',$result)."\n";} // Execution for ($i = 0; $i < 5; $i++) { $callback = create_function('$php','undefined();'); $string = substr($callback,0); // or other function, for example, strval() or str_replace()... show($string); } ?> Expected result: ---------------- It seems, PHP should show error with type E_WARNING. If it's wrong, then I think, NUL-byte is unexpected there. Sorry for my English, I know, it's difficult to read. Thanks!
