What are some best practices for handling header warnings related to session_start() in PHP?
When using session_start() in PHP, it's important to ensure that it is called before any output is sent to the browser. Otherwise, you may encounter header warnings or errors. To avoid this issue, make sure to call session_start() at the beginning of your script, before any HTML or whitespace.
<?php
// Start the session before any output
session_start();
// Rest of your PHP code here
?>
