PHP Domain Availability Check script

The Problem:

There are 70+ domains extensions to check.

Solution I'm looking for

I need to check only the extension the client selected in the index.php <option> + .com/.com.br/.net/.org Those 4 extensions will always be verified, even if the client selected a specific option.

Working example: http://redehost.com.br/registro-de-dominio

I'm looking for something really similar to this /\

index.php

<html>

<head>
<title>99points.info : ajax domain name check</title>

        <script src="http://www.google.com/jsapi" type="text/javascript"></script>
<script src="http://code.jquery.com/jquery-1.8.3.min.js"></script>

<script language="javascript">
$(document).ready(function() {
    
    var loading;
    var results;
    
    form = document.getElementById('form');
    loading = document.getElementById('loading');
    results = document.getElementById('results');
    
    $('#Submit').click( function() {
        
        if($('#Search').val() == "")
        {alert('please enter your domain');return false;}
        
        results.style.display = 'none';
        $('#results').html('');
        loading.style.display = 'inline';
        
        $.post('process.php?domain=' + escape($('#Search').val()),{
        }, function(response){
            
            results.style.display = 'block';
            $('#results').html(unescape(response)); 
            loading.style.display = 'none';
        });
        
        return false;
    });

You don't post the selected extension to your dataservice (process.php).

$.post('process.php?domain=' + escape($('#Search').val())

Should be

$.post('process.php', { domain: escape($('#Search').val()), extension: $('#extensao').val() })

Also you have to define which extensions to check in process.php and skip extensions which are not in this list.

// Add all extensions we need to check to an array
$extensionsToCheck = array('.com', '.com.br', '.net', '.org');
if (isset($_POST['extension']) && !empty($_POST['extension']))
{
    $extensionsToCheck[] = $_POST['extension'];
}   

if(isset($_POST['domain']))
{
    $domain = str_replace(array('www.', 'http://'), NULL, $_POST['domain']);

    if(strlen($domain) > 0)
    {
        foreach($extensions as $extension => $who)
        {
            // Check if we need to check this extensions. Skip if not
            if (!in_array($extension, $extensionsToCheck))
            {
                continue;
            }

Something like this should do. Untested

Thanks for your answer! It's almost working I think. Here's the current output: oi45.tinypic.com/2q0m3hg.jpg - Maybe I have done something wrong? - index.php pastebin.com/RKrwWxk3 process.php - pastebin.com/vifF4gXf
The extensions in the selectlist have a dot in front, you have to strip that one of. See my edited answer.
your posting data from ajax and attempting to use _GET to retrieve it rather than _POST
I have added those trying to fix it, because it wasn't working anyway, you know? Output without dots: oi48.tinypic.com/2ijj63b.jpg Current option template: <option value="ato.br">.ato.br</option> -- EDIT I'll try to remove all dots, even from option field, instead of Value. Edit in a few -- EDIT -- Same result :/
@bizzehdee, he is doing a post request, but the domain and extension are in the uri. It is much better indeed to use jquery post and put those 2 parameters as post data.
