ubuntu - Where are the php files placed after apache is installed?

Question

The browser can open normally by inputting localhost. If I want to open a php file, where should the php file be placed so that it can be accessed through localhost?

Answer 1

By default, if you install it using a package manager, your php files will be placed under /var/www/html.

Answer 2

Look at the ports configured in ports.conf and the directory where each site is configured in sites-available.
If you install apache first and then PHP, you may have to put the apache module of PHP in mods-enabled.
or mods-available inside.
