How to get a users Roles and how to list all WordPress roles in PHP

This code is handy if you want to find out a users role/s. You could expand it and check if a user has a given role or similar.

$user_info = get_userdata(2152);
echo 'Username: ' . $user_info->user_login . "\n";
echo 'User roles: ' . implode(', ', $user_info->roles) . "\n";
echo 'User ID: ' . $user_info->ID . "\n";

$allroles = get_editable_roles();

foreach ($allroles as $k => $v) {

    echo "<br>role = $k ";
}

function get_editable_roles() {
    global $wp_roles;

    $all_roles = $wp_roles->roles;
    $editable_roles = apply_filters('editable_roles', $all_roles);

    return $editable_roles;
}

This code is based on examples from:

and

If you did want to check if the user is in a certain group you could do something like this:

    
    if (in_array('subscriber', $users_roles_array)) {
        
        // do something...
        
    }
