To check if a user is allowed to access a resource, use the session_allowed() function, which takes the following parameters:

• $resource - The name of the resource.
• $access - The level of access. Either 'r', 'w', or 'rw' for Read, Write, or Read and Write.
• $type - The type of resource. This can be one of 'resource', 'access', 'status', and 'team'.

An example use in PHP is:

<?php

if (session_allowed ('sitellite_page', 'r', 'resource')) {
    // can read web pages
} else {
    // can't read web pages
}

?>
