Question

I would like to create a whois function that can check availability for multiple domains (many different words at the same time).

I have this script which works for one single word. How can I get it to check multiple words (one word on each row in the textarea)?

For example if I type in to following in the textarea:

goodword

averygoodword

thisisagreatword

Here is the code:

<?php function checkDomain($domain,$server,$findText){
  // Open a socket connection to the whois server
  $con = fsockopen($server, 43);
  if (!$con) return false;

  // Send the requested doman name
  fputs($con, $domain."\r\n");

  // Read and store the server response
  $response = ' :';
  while(!feof($con)) {
  $response .= fgets($con,128);
  }

  // Close the connection
  fclose($con);

  // Check the response stream whether the domain is available
  if (strpos($response, $findText)){
  return true;
  }
  else {
  return false;
  }
  }

  function showDomainResult($domain,$server,$findText){
  if (checkDomain($domain,$server,$findText)){
  echo "<div id='left'>$domain</div><div id='next'>AVAILEBLE</div><div id='nycontainer'></div>";
  }
  else echo "<div id='left'>$domain</div><div id='next'>TAKEN</div><div id='nycontainer'></div>";
  }
  ?>

Solution

You should be able to split the lines in the textarea into an array using explode with a newline delimiter, then do your WHOIS lookups in a foreach loop.

$manydomains = explode("\n", $domainbase);
foreach ($manydomains as $domain){
<your code here>
}
