note 53677 added to function.preg-match

The following function validates an email address. Does a better job than most validate functions and with very minimal coding. ------------ function is_email($addr) { //Check for illegal sequences. //Note: I had to expand the variable '$illegal' to 2 DIFFERENT lines to allow this post. //php.net complains that this line is too long !!! $illegal = "/(@.*@)|(\.\.)|(@\.)|(\.@)|(^\.)|"; $illegal .= "(\.$)|(^\_)|(\_@)|(\-\-)|(\_\_)/"; //Check for proper format. $format = "/^([a-z0-9\\_\\.]+)@[a-z0-9\\-\\.]+\\.([a-z]+)$/i"; if(!preg_match($illegal, $addr) && preg_match($format,$addr)) return true; return false; } ------------ Sunil Amber http://jformmail.sourceforge.net/ ---- Manual Page -- http://www.php.net/manual/en/function.preg-match.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+53677 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+53677&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+53677&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+53677&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+53677&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+53677&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+53677&report=yes Search -- http://master.php.net/manage/user-notes.php
