[Login form , need help]

Hello, guys i hope you will help me with this cause i'm a complete newbie.

First 2 words about the goal :

I want to make a PHP script to autologin in one webpage and to get statistics in every 2 minutes. The account is mine so i dont want to scam or anything , just want to automate it cause this info i need in realtime, and refreshed often.

The page login page code looks like this :

 

<dl>
                    <dt>Username:</dt>
                    <dd><input type="text" name="user" size="20" value="" class="input_text" /></dd>
                    <dt>Password:</dt>
                    <dd><input type="password" name="passwrd" value="" size="20" class="input_password" /></dd>
                </dl>
                <dl>
                    <dt>Minutes to stay logged in:</dt>

                    <dd><input type="text" name="cookielength" size="4" maxlength="4" value="60" class="input_text" /></dd>
                    <dt>Always stay logged in:</dt>
                    <dd><input type="checkbox" name="cookieneverexp" class="input_check" onclick="this.form.cookielength.disabled = this.checked;" /></dd>
                </dl>
                <p><input type="submit" value="Login" class="button_submit" /></p>

 

and i try login like that :

 

 

 

$_login_url = 'URL of the login'; // url to login 
$_user = 'myusername'; // username for login
$_pass = 'mypass'; // password..
$start = microtime(true);
    file_get_contents(
    $_login_url,
    false,
    stream_context_create(
        array(
          'http' => array(
            'method'  => 'POST',
            'header'  => 'Content-type: application/x-www-form-urlencoded',
            'content' => http_build_query(
            array(
                'user' => $_user,
                'passwrd' => $_pass,
                'cookielength' => '-1',
    //what here ???? 'Login',
                )
              ),
            )
          )
        )
    );
    
      $search['from'] = 'Set-Cookie: ';
      $search['to'] = ';';
      $cookie = array();

 

//the problem is that i cant login to go to the statistics page, cause site requires login for view.
