note 105848 added to reserved.variables.request

The $_REQUEST array is convenient, but sometimes it may lead to confusion, since it contains copies of variables from different sources (GPC), so we must be careful when using. If your program is going to handle large submitted text data, you should remove large text fields in the $_REQUEST as soon as possible to save resources, since the $_REQUEST contains copies from $_POST. For example, when the page runs, delete large data fields in $_REQUEST at very first line to make the program lighter. <?php // delete unuse fields unset($_REQUEST['very_large_text_field']); // continue processing.. ?> ---- Server IP: 69.147.83.197 Probable Submitter: 115.74.0.118 ---- Manual Page -- http://www.php.net/manual/en/reserved.variables.request.php Edit -- https://master.php.net/note/edit/105848 Del: integrated -- https://master.php.net/note/delete/105848/integrated Del: useless -- https://master.php.net/note/delete/105848/useless Del: bad code -- https://master.php.net/note/delete/105848/bad+code Del: spam -- https://master.php.net/note/delete/105848/spam Del: non-english -- https://master.php.net/note/delete/105848/non-english Del: in docs -- https://master.php.net/note/delete/105848/in+docs Del: other reasons-- https://master.php.net/note/delete/105848 Reject -- https://master.php.net/note/reject/105848 Search -- https://master.php.net/manage/user-notes.php
