Consider the following code. What can be said about the call to file_get_contents?

$getdata = "foo=bar";

$opts = array('http' =>

array(

'method' => 'POST',

'header' => 'Content-type: application/x-www-form-urlencoded',

'content' => $getdata

)

);

$context = stream_context_create($opts);

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