How do I send a GET request with a header from PHP?

Question

Call me out if this is a duplicate question, but this is starting to get ridiculous. I want to, with PHP:

 GET http://www.example.com/hello.xyz

You may use file_get_contents if you don't want to use curl but not sure about speed but it's php's built in function where curl is not. When talking about speed then I think whatever you use for a remote request, the speed/performance will depend on the network connection speed more than the function/library and maybe there is a bit different among these (curl/file_get_contents/fsockopen) but I think it'll be a very little (1-2 %) and you can't catch the difference, it'll seem almost same.

$opts = array(
  'http'=>array(
      'method'=>"GET",
      'header'=>"X-Header-Name: $foobar"
));
$context = stream_context_create($opts);
$data = file_get_contents('http://www.example.com/hello.xyz', false, $context);
f($data) {
    // do something with data
}

Also, if you want to use curl then you may use this

$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array("X-Header-Name: $foobar"));
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/hello.xyz");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
curl_close($ch);
if ($curl_errno == 0) {
    // $data received in $data
}
