Edit report at http://bugs.php.net/bug.php?id=52500&edit=1 ID: 52500 Updated by: johannes@php.net Reported by: jason dot gerfen at gmail dot com Summary: Using array_map, strip tags & nested $_POST array -Status: Open +Status: Bogus Type: Bug Package: Scripting Engine problem Operating System: Ubuntu 10 PHP Version: 5.2.14 Block user comment: N New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php this call strip_tags in a way similar to this: strip_tags(array('level-2-1', $var1, 'level-2-2', $var2, 'level-2-3', $var3)); which gives an unexpected result. what you need is wrapper handling the recusrion similar to function strip_tags_recursive($data) { if (is_array($data)) { return array_map('strip_tags_recursive', $data); } else { return strip_tags($data); } } $myget = strip_tags_recursive($_GET); While all this isuntested but shouldgive you the idea.

It seems to discard any secondary iteration of said nested array. Test script: --------------- $_POST = array('level-1-1', $var1, 'level-1-2', $var2, 'level-1-3', $var3, 'level-1-4', array('level-2-1', $var1, 'level-2-2', $var2, 'level-2-3', $var3), 'level-1-5', $var5); $post = array_map(strip_tags, $_POST); echo '<pre>'; print_r($post); echo '</pre>'; /* I am left with this? level-1-1 => $var1 level-1-2 => $var2 level-1-3 => $var3 level-1-5 => $var5 */ Expected result: ---------------- I expected a complete copy of the nested superglobal $_POST. Actual result: -------------- Any nested array information is getting stripped out. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52500&edit=1
