note 36538 added to function.eregi

a simple email validation function: <? function validate_email($string) { //checking that there is only one @, and that there are more than zero chars on both sides of the @ symbol list( $name, $address) = split( "@", $string ); if ( (strlen($name) >= 1) && (strlen($address) >= 1)) { //if the first @ position and the last @ position are on the same char, //there is only one @ on the original email address (r00lez!) $a = strrpos($string, '@'); $b = strpos($string, '@'); if ($a == $b) { //so, if the above is ok, let's check the address list( $domain, $type) = split( ".", $address ); //it does NOT check if the second is a .com, .es or something like that. it only checks that there is an //apparently valid domain on $address (domain.type, or subdomain.domain). you can combine this //function with others on this thread to complete that task... if ( (strlen($domain) >= 1) && (strlen($type) >= 1) ) return(1); //all the above is correct, the email appears to have a valid syntax } else return(0); } else return(0); } ?> it does check that the email syntax is correct. it does not check if the domain exists, or the domain type is correct. just to be merged with functions to do that. ---- Manual Page -- http://www.php.net/manual/en/function.eregi.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+36538 Delete -- http://master.php.net/manage/user-notes.php?action=delete+36538&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+36538&report=yes Search -- http://master.php.net/manage/user-notes.php
