How can the effectiveness of caching in PHP be tested to ensure it is working as expected?

To test the effectiveness of caching in PHP, you can use tools like Apache Benchmark (ab) or Siege to simulate multiple requests to your PHP script and measure the response time. By comparing the response time with and without caching enabled, you can determine if caching is working as expected. 

<?php
// Enable caching
// Start caching
// Run your PHP script
// Stop caching
?>
