How can the arg_separator.output setting be adjusted in PHP to address HTML validation errors related to SessionIDs?

When using session IDs in URLs in PHP, the default arg_separator.output setting may cause HTML validation errors due to the use of special characters like "&" in the session ID. To address this, you can adjust the arg_separator.output setting in your PHP configuration to use a different separator that does not conflict with HTML validation rules, such as a semicolon ";". 

// Set arg_separator.output to use a semicolon ";" instead of "&"
ini_set('arg_separator.output', ';');

// Start the session
session_start();
