Why should you cache your PHP website?

Most web servers are able to handle “normal” traffic and there are plenty of websites which doesn’t have so much traffic. So maybe you ask yourself: Why should you cache your PHP powered website? The apache web server is able to serve many, many files at the same time, but all these files need to be static. A PHP script is parsed by the web server and next the generated HTML data is send to the client (web browser). While this happens the server need to use much more memory than by sending a file to a web client. Imagine what happens if you run/parse a page which is build with WordPress…

The web has not only human visitors!

If your WordPress or PHP site has a few visitors within an hour a web server should be able to serve ALL pages to your visitors without any problems. So far so good, but what if your site get accessed by some bot? The most bad scenario is that these “unnatural” access can slow/take down your site and also all other sites hosted on the same server!
