PHP - echo json off url - php

Question

I am trying to echo json of of a url. I can't figure out how to do it. I have tried many things. Can someone tell me why my code is not functioning properly? No json gets echoed to the screen. Thanks! Here is the link http://www.eastbay.com/shoppingcart/gateway?action=requestKey&_=
<?php
$raw_json = file_get_contents('http://www.eastbay.com/shoppingcart/gateway?action=requestKey&_=');
$json_array = json_decode($raw_json, true);
echo $json_array;
?>

Its not very pretty, you could put this in a loop but it wil get you started, I hope. Only thing you need to do is change the path where you want to store the cookies, it must be an absolute path.
<?php
$cookies = 'C:/folder/folder..../cookies.txt'; //use a absolute path
//Part 1 to get the cookies
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "http://www.eastbay.com");
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookies); // Send Cookies.
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookies); // Receive Cookies.
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
//part 2 to get the json
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "http://www.eastbay.com/shoppingcart/gateway?action=requestKey&_=");
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookies); // Send Cookies.
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookies); // Receive Cookies.
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
// Decoding the json in to an array
$decoded = json_decode($output, true);
//using the array to get the data
echo "RequestKey: " . $decoded['data']['RequestKey'] . "<br>";
echo "Success: ". $decoded['success'] . "<br>";
//foreach loop because its an array which hold the errors, it wont output anything because there are no errors.
foreach($decoded['errors'] AS $error){
echo "Error: " . $error . "<br>";
}
?>
