What steps can be taken to troubleshoot and debug PHP scripts that are not granting the necessary admin rights to users, as experienced in the forum thread?

Issue: PHP scripts are not granting the necessary admin rights to users. This could be due to incorrect permission settings or missing admin role assignments in the code. To troubleshoot and debug this issue, you can start by checking the user roles and permissions in the database or code. Make sure that the admin role is correctly assigned to the users who need it. Additionally, review the code that handles user authentication and role checking to ensure it is functioning correctly.

// Check user role and grant admin rights if necessary
if ($user_role == 'admin') {
    // Grant admin rights
    $admin_rights = true;
} else {
    // Deny admin rights
    $admin_rights = false;
}

// Use the $admin_rights variable to control access to admin functionalities
if ($admin_rights) {
    // Display admin functionalities
    echo "Welcome, Admin!";
} else {
    // Display error message or redirect to a different page
    echo "You do not have admin rights!";
}
