How Can I Send HTTP Headers with PHP's file_get_contents()?

Sending HTTP Headers with PHP's file_get_contents()

Although the file_get_contents() function in PHP does not offer direct support for sending HTTP headers, there are alternative approaches to achieve this.

One method is to create a stream context and configure the HTTP headers within it. This involves setting up an array called $opts that specifies the HTTP method (GET in this example), and adding the desired headers in the header key. For example:

// Create a stream
$opts = [
    "http" => [
        "method" => "GET",
        "header" => "Accept-language: en\r\n" .
            "Cookie: foo=bar\r\n"
    ]
];

// Create the stream context
$context = stream_context_create($opts);

Once the stream context is created, you can pass it as the third argument to file_get_contents() to send the HTTP headers along with the request:

// Send the request with headers
$file = file_get_contents('http://www.example.com/', false, $context);
