You will need a script that integrates with the phpBB framework. Something like this should work.

<?php
define('IN_PHPBB', true);
$phpbb_root_path = (defined('PHPBB_ROOT_PATH')) ? PHPBB_ROOT_PATH : './';
$phpEx = substr(strrchr(__FILE__, '.'), 1);
include($phpbb_root_path . 'common.' . $phpEx);

// Start session management
$user->session_begin();
$auth->acl($user->data);
$user->setup();
?>

Then, look at the $auth->login() function (an example use is in the login_box() function in /includes/functions.php). A simplistic yet incomplete example is:

$result = $auth->login($username, $password); // There are more params but they're optional

if ($result['status'] == LOGIN_SUCCESS)
{
    // Logged in
}
else
{
    // Something went wrong
}

First you need to bootstrap for phpBB:

define('IN_PHPBB', true);
$phpbb_root_path = (defined('PHPBB_ROOT_PATH')) ? PHPBB_ROOT_PATH : './phpBB/';
$phpEx = substr(strrchr(__FILE__, '.'), 1);
include($phpbb_root_path . 'common.' . $phpEx);

$user->session_begin();

You'll have to replace the ./phpBB/ part with the relative path to the forum.

To make the user logged in, you have to do:

$result = $user->session_create($user_id, $admin, $autologin, $viewonline);

$admin should probably be false, $autologin and $viewonline depend on what you want.

NOTE: Calling session_create will set the session cookie for the user, so make sure you only call that when the current request is actually serving that user.

This doesn't answer the OP's question, as your solution is not accepting the user's username/password to log them in, but forcing a login of a specfic $user_id. – Elwood
Fair enough, I did go a bit too far into the details. I'll leave my answer here anyway, since I put some effort into it. Might help someone someday. – Habited
I know that's quite late, but thanks a lot for taking the decision to leave the answer, because that's the only place I've found a solution to how to login users using only the user ID and not the password. – Richellericher
For people looking for a way to change the logged in user, you can do this in a similar manner. $user->session_kill(); $user->session_create($newUserID, false, true); $auth->acl($user->data); I'm using this to switch to an anonymous user (userid=1) before my script does some automatic posting, then switching back to the original user (whos userid I have stored before making the switch). – Wurster

In your PHP script that's crawling through HTML will need to :

  • POST data like if it was filling in the form
  • Get the answer from the server ; probably extract the session's cookies
  • Send those cookies for subsequent requests

You might be interested in using some already-existing library to facilitate that.
For instance, you can take a look at Zend_Http_Client (see also ; the part about Sending Multiple Requests With the Same Client will probably interest you ;-) )


You might also want to take a look at some other questions/answers, like :

Not really sure how this has to do with phpBB? – Elwood
The question was: "How to programmatically log in into phpBB forum?". This is a good general answer explaining that. – Pinnati
@budwiser - The question was how to login to phpBB, not how to generally log into any remote web application. So, it's not well-suited for phpBB, especially when there's an API available and this answer is talking about crawling HTML and remote authentication. (The OP's question clearly states the need for a local authentication solution) – Elwood
