file_get_contents behind a proxy?

The file_get_contents function in PHP can be used to retrieve the contents of a file from a remote server. If your server is behind a proxy, you can use the stream context options to specify the proxy settings when calling file_get_contents.

Here's an example of how you might use the stream_context_create function to set proxy settings for file_get_contents:

<?php

$options = [
    'http' => [
        'proxy' => 'tcp://proxy.example.com:5100',
        'request_fulluri' => true,
    ],
];
$context = stream_context_create($options);

$data = file_get_contents('http://example.com', false, $context);

In this example, the proxy option is set to the address and port of the proxy server, and the request_fulluri option is set to true to ensure that the full URI is passed to the proxy server.

If your proxy requires authentication, you can add the appropriate options to the http array, such as 'header' => 'Proxy-Authorization: Basic '.base64_encode($proxyuser.':'.$proxypass), where $proxyuser and $proxypass are the proxy credentials.
