PHP cURL not being allowed? - php

Question

I'm trying to scrape a page with the use of cURL but all of my attempts doesn't work.
Here's my code:
PHP
public function curl($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
$loc = null;
if(preg_match('#Location: (.*)#', $data, $r)) {
$loc = trim($r[1]);
}
echo "<pre>";
echo var_dump($data);
echo "</pre>";
echo "<pre>";
echo var_dump($loc);
echo "</pre>";
die();
return $data;
}
The response I get by running that is the following:
HTTP/1.1 503 Service Temporarily Unavailable

I don't really know what to make of it as I don't understand what the problem is. Can anyone help me?
