在PHP中将post参数添加到file_get_contents

Question

I want to ask you how to add POST parameter to php file in file_get_contents function. I tried something like this, but its not working:

$getdata = http_build_query(
            array(
                'user_id' => $_SESSION['user_id'],
                'firstname'=>$firstname,
                'lastname' =>$lastname
            )
    );

    $opts = array('http' =>
        array(
            'method' => 'POST',
            'header'  => 'Content-type: application/x-www-form-urlencoded',
            'content' => $getdata
        )
    );

    $context = stream_context_create($opts);

    $this->body = file_get_contents('templates/email/email_after_registration.php', false, $context);
    echo 'content' . $this->body;
    exit();

In output is only 'content' and static html text, In 'templates/email/email_after_registration.php' I want also use $_POST['firstname'] , $_POST['lastname'] , $_POST['user_id'] , but they are empty :( .

Different solutions:

1) If you set second parameter as false

Means that you are not using inclusion and you need the full path

file_get_contents('http://{HOST}/templates/email/email_after_registration.php', false, $context);

Have a look in detail HERE

2) Use inclusion instead?

$_POST['user_id'] = $_SESSION['user_id'];
$_POST['firstname'] = $firstname;
$_POST['lastname'] = $lastname;

ob_start();
include('templates/email/email_after_registration.php');
$this->body = ob_get_clean();
echo 'content' . $this->body;
exit();

Answer 2

我倾向于为此使用cURL。
