note 71898 added to ref.filter

Also notice that filter functions are using only the original variable values passed to the script even if you change the value in super global variable ($_GET, $_POST, ...) later in the script. <?php echo filter_input(INPUT_GET, 'var'); // print 'something' echo $_GET['var']; // print 'something' $_GET['var'] = 'changed'; echo filter_input(INPUT_GET, 'var'); // print 'something' echo $_GET['var']; // print 'changed' ?> In fact, external data are duplicated in SAPI before the script is processed and filter functions don't use super globals anymore (as explained in Filter tutorial bellow, section 'How does it work?'). ---- Server IP: 212.24.129.110 Probable Submitter: 84.42.163.192 ---- Manual Page -- http://www.php.net/manual/en/ref.filter.php Edit -- https://master.php.net/note/edit/71898 Del: integrated -- https://master.php.net/note/delete/71898/integrated Del: useless -- https://master.php.net/note/delete/71898/useless Del: bad code -- https://master.php.net/note/delete/71898/bad+code Del: spam -- https://master.php.net/note/delete/71898/spam Del: non-english -- https://master.php.net/note/delete/71898/non-english Del: in docs -- https://master.php.net/note/delete/71898/in+docs Del: other reasons-- https://master.php.net/note/delete/71898 Reject -- https://master.php.net/note/reject/71898 Search -- https://master.php.net/manage/user-notes.php
