How can the issue of 'array' being output instead of the session ID be addressed in PHP?

The issue of 'array' being output instead of the session ID in PHP can be addressed by ensuring that the session_start() function is called before trying to access or output the session ID. This function initializes a session or resumes the current one based on a session identifier passed via a GET or POST request, or passed via a cookie. 

<?php
session_start();
echo session_id();
?>
