How can the configuration of PHP, particularly the output_buffering setting in php.ini, affect the functionality of session handling functions like session_start()?

The output_buffering setting in php.ini can affect the functionality of session handling functions like session_start() because it buffers the output before sending it to the client. This can cause issues with session data not being saved or retrieved correctly. To solve this issue, you can disable output buffering or ensure that session_start() is called before any output is sent to the client. 

<?php
// Disable output buffering
ini_set('output_buffering', 'off');

// Start the session
session_start();

// Your PHP code here
?>
