note 84329 added to function.filter-var

Here is how to use multiple flags (for those who learn better by example, like me): <?php echo "|asdf".chr(9).chr(128)."_123|"; echo "\n"; // "bitwise conjunction" means logic OR / bitwise | echo filter_var("|asdf".chr(9).chr(128)."_123\n|" ,FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_LOW | FILTER_FLAG_STRIP_HIGH); /* Results: |asdf �_123| |asdf_123| */ ?> ---- Server IP: 208.69.120.35 Probable Submitter: 216.248.11.38 ---- Manual Page -- http://www.php.net/manual/en/function.filter-var.php Edit -- https://master.php.net/note/edit/84329 Del: integrated -- https://master.php.net/note/delete/84329/integrated Del: useless -- https://master.php.net/note/delete/84329/useless Del: bad code -- https://master.php.net/note/delete/84329/bad+code Del: spam -- https://master.php.net/note/delete/84329/spam Del: non-english -- https://master.php.net/note/delete/84329/non-english Del: in docs -- https://master.php.net/note/delete/84329/in+docs Del: other reasons-- https://master.php.net/note/delete/84329 Reject -- https://master.php.net/note/reject/84329 Search -- https://master.php.net/manage/user-notes.php
