note 93173 added to function.filter-has-var

To julien: isset is NOT the same as filter_has_var, since the first will check the array itself, while filter_has_var will use the data received in the HTTP data. Someone already mentioned how it works below, but this is just to point out that there's a difference. ---- Server IP: 200.36.127.20 Probable Submitter: 189.190.150.121 ---- Manual Page -- http://www.php.net/manual/en/function.filter-has-var.php Edit -- https://master.php.net/note/edit/93173 Del: integrated -- https://master.php.net/note/delete/93173/integrated Del: useless -- https://master.php.net/note/delete/93173/useless Del: bad code -- https://master.php.net/note/delete/93173/bad+code Del: spam -- https://master.php.net/note/delete/93173/spam Del: non-english -- https://master.php.net/note/delete/93173/non-english Del: in docs -- https://master.php.net/note/delete/93173/in+docs Del: other reasons-- https://master.php.net/note/delete/93173 Reject -- https://master.php.net/note/reject/93173 Search -- https://master.php.net/manage/user-notes.php
