Are there any specific PHP functions or headers that can be used to control browser caching behavior?

Browser caching behavior can be controlled using the "Cache-Control" header in PHP. By setting specific cache-control directives, you can instruct the browser on how long to cache resources like images, CSS files, and scripts. This can help improve website performance by reducing the number of requests made to the server. 

<?php
// Set cache control headers to control browser caching behavior
header("Cache-Control: max-age=3600, public"); // Cache resource for 1 hour
