Re: Validating Email Conditional

Hi, My script is working, but valid returns true even if the user is bogus. What needs changing so both conditions have to match, the following attempt returned "unexpected logical...." if (getmxrr($domaintld,$mxrecords)) && if(fsockopen($domaintld,25,$errno,$errstr,30)) {

         $valid = true;
         }

You don't need to write the second 'if', just wrap the two conditionals in parentheses:

if ( getmxrr($domaintld,$mxrecords) && fsockopen($domaintld,25,$errno,$errstr,30) ) $valid = true; You could equally use nested conditionals: if (getmxrr($domaintld,$mxrecords)) { if (fsockopen($domaintld,25,$errno,$errstr,30))

     $valid = true;

} There is no need for the second $valid = false in your code below, since you define that at the start. Edward

The following works, but needs the conditional mentioned... <?php $email = "lotus@bushidodeep.com"; $valid=""; function validate_email($email) { // Create the syntax of email with validation regular expression $regexp = "^([_a-z0-9-]+)(\.[_a-z0-9-]+)*@([a-z0-9-]+)(\.[a-z0-9-]+)*(\.[a-z]{2,4})$"; // Presume that the email is invalid $valid = false; // Validate the syntax if (eregi($regexp, $email)) {

      list($username,$domaintld) = split("@",$email);
      // Validate the domain
      if (getmxrr($domaintld,$mxrecords))
         $valid = true;
         }
    // attempts a socket connection to mail server

if(fsockopen($domaintld,25,$errno,$errstr,30)) {

        $valid = true;

} else {

          $valid = false;

}

     return $valid;

} if (validate_email($email)) echo "Email is valid!"; else echo "Email is invalid!"; ?> --PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
