[PHP] Xbox Live Gamertag Checker

This literally took me 5 minutes to code.

All it does is checks if a Xbox Live Gamertag is available for you to use.
You simply enter a gamertag and press the button.

index.php

PHP Code:

---

<?php
if( $_POST['check'] )
{
    $gt = strip_tags( $_POST['gt'] );
    $exists = false;
    if( empty( $gt ) )
    {
        header( "Location: " . $_SERVER['PHP_SELF'] );
    }
    else
    {
        $check_url = "http://gamercard.xbox.com/en-GB/" . $gt . ".card";
        $check_url_source = file_get_contents( $check_url );
        $exists = ( eregi( "<div class=\"Stat\">--</div>", $check_url_source ) && eregi( "<div class=\"NoGame\"></div>", $check_url_source ) ) ? false : true;
        echo ( $exists == true ) ? "The gamertag <strong>" . $gt . "</strong> is already in use!" : "The gamertag <strong>" . $gt . "</strong> is not in use! You are free to use it.";
    }
}
else
{
    echo "Enter a Xbox Live Gamertag to see if it is already in use.<br>
    <form method=\"post\">
        <input type=\"text\" name=\"gt\" value=\"\" maxlength=\"1000\"> <input type=\"submit\" name=\"check\" value=\"&raquo;\">
    </form>";
}
?>
