Are there any best practices for compressing output in PHP to save traffic?

When sending data over the network in PHP, it's important to consider compressing the output to save on bandwidth and improve loading times. One common method is to use gzip compression, which can significantly reduce the size of the data being sent. This can be achieved by setting the appropriate headers in PHP to indicate that the output should be compressed. 

// Enable gzip compression
ob_start("ob_gzhandler");

// Set appropriate headers
header('Content-Encoding: gzip');
header('Vary: Accept-Encoding');
