    Try this:

    <!doctype html>
<?php

if (!empty($_POST['signed_request'])) {
    list($sig, $payload) = explode('.', $_POST['signed_request'], 2);
    $decoded = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);
    $liked = $decoded["page"]["liked"];
}

if ($liked) {
    header('Location:youlike.php');
    exit;
}
else {
      echo "you don't like";
}
?>
