veryfying emails in loop

[graham23s]

Hi Guys,

 

im trying to mass verify the emails addresses using:

 

mass-verify.php

 

<?php
include("inc/inc-sessions.php");
include("inc/inc-db-connection.php");
include("inc/inc-functions.php");
include("inc/inc-header.php");
include("inc/inc-nav-1.php");

print("<center><form action=\"\" method=\"post\"><input type=submit name=mass_ver value=GO></form>");

if (isset($_POST['mass_ver']))
{
  print("started...");
  
  // query
  $q = "SELECT * FROM `SYLA_EMAILS`";
  $r = mysql_query($q);
  
  while ($a = mysql_fetch_array($r))
  {
       $id = $a['ID'];
    $email = $a['EMAIL'];
    
    $error = validateEmail($email, true, true, 'postmaster@tienhuis.nl', 'outkast.tienhuis.nl', true);
  
    if (isset($error))
    {
    
    $updateQ = mysql_query("UPDATE `SYLA_EMAILS` SET `EMAIL_STATUS`='F' WHERE `ID`='$id'");  
    
    } else {
    
    $updateQ = mysql_query("UPDATE `SYLA_EMAILS` SET `EMAIL_STATUS`='Y' WHERE `ID`='$id'");  
    
    }
  
  }
  
  
} // end isset
?>

 

function:

 

function validateEmail($email, $domainCheck = false, $verify = false, $probe_address = '', $helo_address = '', $return_errors = false) { 
    global $debug; 
    $server_timeout = 180; # timeout in seconds. Some servers deliberately wait a while (tarpitting) 
    if($debug) {echo "<pre>";} 
    # Check email syntax with regex 
    if (preg_match('/^([a-zA-Z0-9\._\+-]+)\@((\[?)[a-zA-Z0-9\-\.]+\.([a-zA-Z]{2,7}|[0-9]{1,3})(\]?))$/', $email, $matches)) { 
        $user = $matches[1]; 
        $domain = $matches[2]; 
        # Check availability of DNS MX records 
        if ($domainCheck && function_exists('checkdnsrr')) { 
            # Construct array of available mailservers 
            if(getmxrr($domain, $mxhosts, $mxweight)) { 
                for($i=0;$i<count($mxhosts);$i++){

                } 
                asort($mxs); 
                $mailers = array_keys($mxs); 
            } elseif(checkdnsrr($domain, 'A')) { 
                $mailers[0] = gethostbyname($domain); 
            } else { 
                $mailers=array(); 
            } 
            $total = count($mailers); 
            # Query each mailserver 
            if($total > 0 && $verify) { 
                # Check if mailers accept mail 
                for($n=0; $n < $total; $n++) { 
                    # Check if socket can be opened 
                    if($debug) { echo "Checking server $mailers[$n]...\n";} 
                    $connect_timeout = $server_timeout; 
                    $errno = 0; 
                    $errstr = 0; 
                    # Try to open up socket 
                    if($sock = @fsockopen($mailers[$n], 25, $errno , $errstr, $connect_timeout)) { 
                        $response = fgets($sock); 
                        if($debug) {echo "Opening up socket to $mailers[$n]... Succes!\n";} 
                        stream_set_timeout($sock, 30); 
                        $meta = stream_get_meta_data($sock); 
                        if($debug) { echo "$mailers[$n] replied: $response\n";} 
                        $cmds = array( 
                            "HELO $helo_address", 
                            "MAIL FROM: <$probe_address>", 
                            "RCPT TO: <$email>", 
                            "QUIT", 
                        ); 
                        # Hard error on connect -> break out 
                        # Error means 'any reply that does not start with 2xx ' 
                        if(!$meta['timed_out'] && !preg_match('/^2\d\d[ -]/', $response)) { 
                            $error = "Error: $mailers[$n] said: $response\n"; 
                            break; 
                        } 
                        foreach($cmds as $cmd) { 
                            $before = microtime(true); 
                            fputs($sock, "$cmd\r\n"); 
                            $response = fgets($sock, 4096); 
                            $t = 1000*(microtime(true)-$before); 
                            if($debug) {echo htmlentities("$cmd\n$response") . "(" . sprintf('%.2f', $t) . " ms)\n";} 
                            if(!$meta['timed_out'] && preg_match('/^5\d\d[ -]/', $response)) { 
                                $error = "Unverified address: $mailers[$n] said: $response"; 
                                break 2; 
                            } 
                        } 
                        fclose($sock); 
                        if($debug) { echo "Succesful communication with $mailers[$n], no hard errors, assuming OK";} 
                        break; 
                    } elseif($n == $total-1) { 
                        $error = "None of the mailservers listed for $domain could be contacted"; 
                    } 
                } 
            } elseif($total <= 0) { 
                $error = "No usable DNS records found for domain '$domain'"; 
            } 
        } 
    } else { 
        $error = 'The e-mail address looks funny! was it typed correctly?'; 
    } 
    if($debug) { echo "</pre>";} 
     
    if($return_errors) { 
        # Give back details about the error(s). 
        # Return FALSE if there are no errors. 
        if(isset($error)) return htmlentities($error); else return false; 
    } else { 
        # 'Old' behaviour, simple to understand 
        if(isset($error)) return false; else return true; 
    } 
} 

 

while looping so each email gets checked! it has set it all to F i know the reson is becuase it found errors it just set them all to F but im not sure the best way to check them in the while loop!

 

any ideas would be great!

 

cheers

In your function you need some sort of return statement.

 

At the bottom, before the last } put this:

 

return $error;

 

Also, at the top, under the global, put this:

 

$error = "";

 

Then make your if() statement on your mass-verify.php this:

 

if(!empty($error)){

 

That basically means that if $error is not empty (meaning the email is invalid), it will update the email with F. So you may need to reverse it (removing the ! at the start), so that if you encountered no errors it updates with F.
