Best way to add latest PHP

I am nginx perfect server on running debian 10.13 and need to install the latest PHP.

What is the best or most current tutorial for adding current PHP?

 

Look at ISPConfig Documentation page, it has "Using multiple PHP versions".
Internet Search Engines find also this: https://www.howtoforge.com/ispconfig-php-debian/ , which may be most recent.

 

Thanks for the reply,

Yes that went without any problems,

I did not add anything under

PHP-FPM Settings
PHP-FPM socket directory

was I supposed to add something here?

 

The instructions do not say anything about PHP-FPM socket directory, so I have left it empty. No problems so far.
