How can the code be modified to ensure the correct inclusion of the 'cl_user' file?

The issue with the current code is that the include path for the 'cl_user' file is not correctly specified. To ensure the correct inclusion of the 'cl_user' file, we need to specify the correct path to the file relative to the current file. This can be done by using the `__DIR__` magic constant to get the directory of the current file and then appending the relative path to the 'cl_user' file.

// Specify the correct path to the 'cl_user' file relative to the current file
include __DIR__ . '/path/to/cl_user.php';
