如何保存通过curl获取的xml文件？

Question

I have this proxy done using curl. I t successfully gets the xml to be displayed in the page. I'm trying to save a copy locally with no success, i tried (already in the complete code below):

$fp = fopen('data.xml', 'w');
fwrite($fp, $xml);
fclose($fp);

But I got no error and an empty "data.xml" file...How can this be done? thanks

[EDIT2]: solved, i just added the flag: curl_setopt($session, CURLOPT_RETURNTRANSFER, true); and done! (updated in the code below The code with @spell suggestion.

define ('HOSTNAME', 'http://www.camara.gov.br');


$path = "http://www.camara.gov.br/SitCamaraWS/Deputados.asmx/ObterDeputados?";
$url = HOSTNAME.$path;

$session = curl_init($path);
curl_setopt($session, CURLOPT_HEADER, false);
curl_setopt($session, CURLOPT_HTTPGET, true);
curl_setopt($session, CURLOPT_RETURNTRANSFER, true);
curl_setopt($session, CURLOPT_USERAGENT, 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.76 Safari/537.36');

header("Content-Type: text/xml");


$xml = curl_exec($session);


curl_close($session);

file_put_contents ('./data.xml', $xml); 
?>

You can just use file_put_contents function.

In your case it will be:

// Make the call
$xml = curl_exec($session);


// done, shutDown.
curl_close($session);

if (file_put_contents ('./data.xml', $xml) !== false) {
     echo 'Success!';
} else {
     echo 'Failed';
}

And

But I got no error and an empty "data.xml" file

Next time provide an error
