			0 ignored issues – show Security Best Practice introduced 2017-03-02 08:09 UTC by Report Bug Copy Issue Report The use of `create_function` is highly discouraged, better use a closure. `create_function` can pose a great security vulnerability as it is similar to `eval`, and could be used for arbitrary code execution. We highly recommend to use a closure instead. // Instead of $function = create_function('$a, $b', 'return $a + $b'); // Better use $function = function($a, $b) { return $a + $b; } Loading history...
