How can output buffering be used to prevent header modification errors in PHP?
Output buffering can be used to prevent header modification errors in PHP by buffering the output before any headers are sent. This ensures that headers are not modified after they have already been sent, which can cause errors. By using output buffering, you can safely modify headers and content without worrying about interfering with each other.
<?php
ob_start(); // Start output buffering
// Code that may modify headers or content
ob_end_flush(); // Flush the output buffer
