Are there any best practices to avoid session cookie errors in PHP?

Session cookie errors in PHP can be avoided by ensuring that the session_start() function is called before any output is sent to the browser. This is because session cookies must be set in the HTTP headers before any content is sent. Additionally, make sure that the session cookie parameters are set correctly, such as the session cookie domain and path. 

<?php

// Start the session before any output
session_start();

// Set session cookie parameters
session_set_cookie_params(0, '/', 'example.com', false, true);

// Rest of your PHP code here

?>
