How can a PHP script be executed several times while the URL is requested only once?

edit

One way to execute a PHP script several times while the URL is requested only once is to use a loop within the script. For example, if you want to execute a certain code block five times, you can create a loop that runs five iterations within the script. This way, when the URL is requested once, the script will execute the loop and run the code block five times.

Another way to achieve this is by implementing server-side caching. Caching allows the server to store the result of a requested URL so that when the same URL is requested again, the server can return the cached result instead of running the PHP script again. This can greatly improve website performance and reduce server load.
