$ _SESSION和$ _REQUEST之间的关系

Question

Here's my case :

I'm using SugarCRM's API, and to make a call, I had to patch some functions to make things work. In one of the function, I had to rewrite this code :

$credentials = array('user_name'=>"xxxxxxx", 'password'=>md5("xxxxx"));
    if (SugarWebServiceImpl::login($credentials, null, null)) {
    global $current_user;
    require_once('modules/Users/User.php');
    $current_user = new User();
    $current_user->retrieve($_SESSION['user_id']);
    $this->login_success();
    return true;
}

My problem is that on the same call, my variable $_REQUEST becomes empty. My question is simple then :

is there any relation between the $_SESSION variable and the $_REQUEST variable. Does the $_REQUEST empties herself when a new $_SESSION is set ?

Answer 1

No, There is not. According to PHP Manual

$_REQUEST is An associative array that by default contains the contents of $_GET, $_POST and $_COOKIE.

However that just answers your question but doesn't solve the problem. If that issue happens here

$current_user->retrieve($_SESSION['user_id']);

then it would help to be able to see that retrieve method
