Thought I would share this bit of code with everyone.

I asked for help with this problem in the other thread listed here. I thought I would share the code that I was helped create. The function used is the last bit of information I needed to complete the domain check routine I was trying to do. Look it over and let me know what you think. Do you think it could be coded better? Post back something you would have done different.

<?php

set_time_limit(0);
ob_start();

function MakePairs($num_array) {
    $pairs = array();
    foreach($num_array as $outer) {
        foreach($num_array as $inner) {
        
            if($outer != $inner)
                $pairs[] = trim($outer).trim($inner).".com";
        }
    }
   
    return $pairs;
}


function say($str) 
{
  echo $str;
  ob_flush();
  flush();
  return;
}

function sayln($str)
{
  echo $str."<br />";
  ob_flush();
  flush();
  return;
}

if(isset($_POST['submit']))
{ 

   sayln('Checking for free domains :) Wee...');
   $domains = explode("\n", $_POST['domains']); 
   $newpairs = MakePairs($domains);
   $num = count($newpairs);
   sayln("checking ".$num." domains");
 foreach($newpairs as $domain)
 {
     $domain = trim($domain);
     
     sayln("Checking: $domain");
     
     $buffer = null;       
     $ch = curl_init();
      curl_setopt($ch, CURLOPT_URL,"whois.crsnic.net:43");
      curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
      curl_setopt($ch, CURLOPT_TIMEOUT, 10);
      curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "$domain\r\n");
     $buffer = curl_exec($ch);
     curl_close($ch);
     
     if(eregi('No match for', $buffer)) 
      {
        $found[] = $domain;
        //sayln($domain);
      }
       
 }
 sayln("<pre>");
 print_r($found);
 sayln("</pre>");
}  
else { ?>

<div style="text-align: center">
    <form action="index2.php" method="post">
        <textarea name="domains" cols="100" rows="20"></textarea>
        <br /><input type="submit" name="submit" value="Check For Free Domains" style="font-size: 30pt;" />
    </form>
</div>
<?php
} 
?>
