note 99183 added to function.stripslashes

Here's a way of stripping slashes in PHP 5.3 using a recursive closure: <?php if (get_magic_quotes_gpc()) { $strip_slashes_deep = function ($value) use (&$strip_slashes_deep) { return is_array($value) ? array_map($strip_slashes_deep, $value) : stripslashes($value); }; $_GET = array_map($strip_slashes_deep, $_GET); $_POST = array_map($strip_slashes_deep, $_POST); $_COOKIE = array_map($strip_slashes_deep, $_COOKIE); } ?> Note that the variable '$strip_slashes_deep' has to be passed to the closure by reference. I think that this is because at the time the closure is created the variable '$strip_slashes_deep' doesn't exist: the closure itself becomes the value of the variable. Passing by reference solves this issue. This closure could easily be adapted to use other methods of stripping slashes such as preg_replace(). ---- Server IP: 66.207.199.35 Probable Submitter: 65.95.29.196 ---- Manual Page -- http://www.php.net/manual/en/function.stripslashes.php Edit -- https://master.php.net/note/edit/99183 Del: integrated -- https://master.php.net/note/delete/99183/integrated Del: useless -- https://master.php.net/note/delete/99183/useless Del: bad code -- https://master.php.net/note/delete/99183/bad+code Del: spam -- https://master.php.net/note/delete/99183/spam Del: non-english -- https://master.php.net/note/delete/99183/non-english Del: in docs -- https://master.php.net/note/delete/99183/in+docs Del: other reasons-- https://master.php.net/note/delete/99183 Reject -- https://master.php.net/note/reject/99183 Search -- https://master.php.net/manage/user-notes.php
