IF statement inside FOREACH loop headache

[al]

I have a if statement inside foreach loop with one problem I'm banging my head for a while now.

I would like to test (IF ALL Authoritative DNS servers responded successful to query then print (RESPONSE OK) ONLY ONCE IF ALL SERVERS RESPONDED OK ELSE IF NOT print only server which did not responded).

 

thanks.

 

          
           //////////////////////////
          // Test 1///////////////
          /////////////////////////

              foreach ($response->authority as $k => $result) {

              // Get Authoritative DNS servers 
              $authns = array(gethostbyname($result->nsdname));

              // Initiate Authoritative DNS servers for query
              $dnsservers = new Net_DNS_Resolver(array('nameservers' => $authns));

              // Query Authoritative DNS servers one by one
              $responsedns = $dnsservers->rawQuery($domain);

              // Get an array of DNS Authoritative servers which responded OK
              $resns  = array($responsedns->answerfrom);


// IF ALL Authoritative DNS servers responded successful to query then print (RESPONSE OK) ONLY ONCE 
//  ELSE IF NOT print only server which did not responded)
                     if ($authns == $resns){
                     echo "<font size=2 color=green> (response ok)</font><br>";
                     } else {
                     echo $result->nsdname;
                     }

             }

             }
}

This line is bad. You cannot compare 2 arrays. You must compare values

if ($authns == $resns){

Try this

<?php
$results['success'] = 0;
$results['failure'] = array();
foreach($response->authority as $k => $result) {
// Get Authoritative DNS servers 
$authns = array(gethostbyname($result->nsdname));
// Initiate Authoritative DNS servers for query
$dnsservers = new Net_DNS_Resolver(array('nameservers' => $authns));
// Query Authoritative DNS servers one by one
$responsedns = $dnsservers->rawQuery($domain);
// Get an array of DNS Authoritative servers which responded OK
$resns  = array($responsedns->answerfrom);

    //if ($authns == $resns){
if($authns[0] == $resns[0]) {
	$results['success']++;
    } 
else {
    	$results['failure'][] = $result->nsdname;
}

}
// print the results
print "<h1>Results</h1>";
print "OK Responses: ".$results['success']."<br />";
print "Failed Responses: ".count($results['failure'])."<br />".implode("<br />", $results['failure']);
?>

Thank you Neil I'm very grateful for this.
