问题
When I change a file in the directory, the change is not reflected on the web page shown when I access it through localhost, but it is shown when I access it directly by the file path on my system. Why?
I am on a Windows machine. My files are stored at C:\Program Files (x86)\Ampps\www\connor.dev . When I directly reference a file, by going to a link like this in the browser, file:///C:/Program%20Files%20(x86)/Ampps/www/connor.dev/index.php, the changes I made and saved in Sublime Text are shown. When I access it by going to localhost/connor.dev/, the changes are not shown. Even if I delete the file completely, it is still shown in localhost. This started happening recently on xampp, so I uninstalled it and used Ampps, and now the same thing is happening. If you need more info please ask.

Press Ctrl-F5 to hard refresh the page (to not use Browser's cache).
If you still see the previous pages or changes, then Apache has mod_cache caching them, or PHP has its opcode cache settings set to not refresh changes for X amount of time.

I'm using Bitnami and the way I fixed it was to go inside C:\Bitnami\wappstack-version-number\php\php.ini, you can make the following changes and then reset your server:
opcache.enable=0
opcache.revalidate_freq=0
My php was updating every 60 seconds before, so I decided to turn that to 0 and just disable caching.

Its happening because of apache mod_cache caching the resources.
For quick fix. Just restart the Apache server.
In ubuntu i use this below command in terminal to restart the Apache server
systemctl restart apache2
Now refresh the browser, then you will get the updated one.
