如何保存Netflix即时目录的gzip压缩副本？

我在Netflix的网站上使用了一个教程，以正确下载特定电影的API查询的gzip。当我更改代码以下载整个Netflix目录的gzip时，该脚本不再适用。如何保存Netflix即时目录的gzip压缩副本？

当我运行脚本时，API查询以“？output = json;”结尾。这不会返回结果。当我手动删除尾随分号时，目录会在我的浏览器窗口中下载。由于它的大小，这不完全是一种选择。

Netflix的教程：http://developer.netflix.com/page/resources/sample_php

我的修改：

<?php 
include ('OAuthSimple.php'); 
$apiKey = 'MY KEY'; 
$sharedSecret = 'MY SECRET'; 

/* THIS CODE BLOCK WORKS 
$arguments = Array( 
    term=>'fargo', 
    expand=>'formats,synopsis', 
    max_results=> '1', 
    output=>'json' 
); */ 


$arguments = Array(
    output=>'json' 
); 
//$path = "http://api-public.netflix.com/catalog/titles"; // ORIGINAL CODE FOR MOVIE SEARCH 
$path = "http://api-public.netflix.com/catalog/titles/streaming"; // Full Catalog Search 

$oauth = new OAuthSimple(); 
$signed = $oauth->sign(Array(path=>$path, 
       parameters=>$arguments, 
       signatures=> Array('consumer_key'=>$apiKey, 
            'shared_secret'=>$sharedSecret 
            ))); 

// Now go fetch the data. 
$curl = curl_init(); 
curl_setopt($curl,CURLOPT_URL,$signed['signed_url']); 
curl_setopt($curl,CURLOPT_HTTPHEADER,array('Accept-Encoding: gzip')); 
curl_setopt($curl,CURLOPT_RETURNTRANSFER,1); 
curl_setopt($curl,CURLOPT_SETTIMEOUT,2); 
$buffer = curl_exec($curl); 
if (curl_errno($curl)) 
{ 
    die ("An error occurred:".curl_error()); 
} 
curl_close($curl); 
//$result = json_decode($buffer); 

$fp = fopen('data.gzip', 'w'); 
fwrite($fp, $buffer); 
fclose($fp); 
?> 
<p> 
<b>Your signed URL:</b></br> 
<?php print $signed['signed_url'] ?>; 
</p> 
<p> 
And the output is:</br> 
<pre> 
<?php 
print print_r($buffer); ?> 
</pre> 
</p>
