note 104029 added to filter.examples.validation

I used filter_var and preg_match in a email validation function. I try these and get same results with them. It was useful and simple; function checks_email($value = '') { $value = trim($value); if (function_exists('filter_var')) { $value = filter_var($value, FILTER_SANITIZE_EMAIL); if (filter_var($value, FILTER_VALIDATE_EMAIL)) return true; else return false; } else return preg_match('/^[a-z0-9\,\!\#\\\$\%\&\'\*\+\/\= \?\^\_\`\{\|\}\~\-]+(\.[a-z0-9\,\!\#\\\$\%\&\'\*\+\/\=\?\^\_ \`\{\|\}\~\-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*\.([a-z]{2,})$/i', $value); } ---- Server IP: 69.147.83.197 Probable Submitter: 31.141.87.97 ---- Manual Page -- http://www.php.net/manual/en/filter.examples.validation.php Edit -- https://master.php.net/note/edit/104029 Del: integrated -- https://master.php.net/note/delete/104029/integrated Del: useless -- https://master.php.net/note/delete/104029/useless Del: bad code -- https://master.php.net/note/delete/104029/bad+code Del: spam -- https://master.php.net/note/delete/104029/spam Del: non-english -- https://master.php.net/note/delete/104029/non-english Del: in docs -- https://master.php.net/note/delete/104029/in+docs Del: other reasons-- https://master.php.net/note/delete/104029 Reject -- https://master.php.net/note/reject/104029 Search -- https://master.php.net/manage/user-notes.php
