I do a fair bit of PHP coding on my local machine here.

One of the most irritating aspects of that is when I change a bit of coding and run the browser, the modification fails to appear, as the browser shows the old cached version.  This is particularly irritating if the code takes a length of time to run.

There is a very simple and effective fix.

Open php.ini and change the line opcache.enable=1 to opcache.enable=0

Problem solved.

I just wish I had found that years ago!
