note 126028 added to function.filter-var

I cannot confirm what yactouat said. As of PHP 7.3, 0 will not be filtered out with FILTER_VALIDATE_INT. It correctly returns 0, not false. Of course you have to check the return value with an identity operator. Otherwise you cannot distinguish between 0 and false. ---- Server IP: 45.112.84.4 Probable Submitter: 45.112.85.242 (proxied: 80.135.78.51) ---- Manual Page -- https://php.net/manual/en/function.filter-var.php Edit -- https://main.php.net/note/edit/126028 Del: integrated -- https://main.php.net/note/delete/126028/integrated Del: useless -- https://main.php.net/note/delete/126028/useless Del: bad code -- https://main.php.net/note/delete/126028/bad+code Del: spam -- https://main.php.net/note/delete/126028/spam Del: non-english -- https://main.php.net/note/delete/126028/non-english Del: in docs -- https://main.php.net/note/delete/126028/in+docs Del: other reasons-- https://main.php.net/note/delete/126028 Reject -- https://main.php.net/note/reject/126028 Search -- https://main.php.net/manage/user-notes.php
