file_get_contents behind a proxy?

by

To use file_get_contents() over/through a proxy that doesn’t require authentication, something like this should do :

(I’m not able to test this one : my proxy requires an authentication)

$aContext = array(
    'http' => array(
        'proxy'           => 'tcp://192.168.0.2:3128',
        'request_fulluri' => true,
    ),
);
$cxContext = stream_context_create($aContext);

$sFile = file_get_contents("http://www.google.com", False, $cxContext);

echo $sFile;

Of course, replacing the IP and port of my proxy by those which are OK for yours 😉

If you’re getting that kind of error :

Warning: file_get_contents(http://www.google.com) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.0 407 Proxy Authentication Required

It means your proxy requires an authentication.

If the proxy requires an authentication, you’ll have to add a couple of lines, like this :

$auth = base64_encode('LOGIN:PASSWORD');

$aContext = array(
    'http' => array(
        'proxy'           => 'tcp://192.168.0.2:3128',
        'request_fulluri' => true,
        'header'          => "Proxy-Authorization: Basic $auth",
    ),
);
$cxContext = stream_context_create($aContext);

$sFile = file_get_contents("http://www.google.com", False, $cxContext);

echo $sFile;

Same thing about IP and port, and, this time, also LOGIN and PASSWORD 😉 Check out all valid http options.

Now, you are passing an Proxy-Authorization header to the proxy, containing your login and password.

And… The page should be displayed 😉
