I'm glad to hear that it works!

But Laragon comes with its own Apache, and you can always download the latest Apache from Apache Lounge

I have Apache on both Laragon and WampServer, and it works without any problem.

The same with MySQL, but here I point Laragon's MySQL to the data folder on WampServer, so I can switch from Laragon with PHP8 to WampServer with PHP7, while testing the same Website with the same data. 

You can download the Windows PHP 8 binaries from: https://windows.php.net/qa/

Unzip it to your Laragon folder, e.g. C:\laragon\bin\php\

so you have: C:\laragon\bin\php\php-8.0.0beta2-Win32-vs16-x64\

Then start Laragon.

It should find PHP8, and you should see it in your Laragon PHP selection. 

After you select PHP8, you will get an error, so stop Laragon and make these changes:

1. Open the file: C:\laragon\etc\apache2\mod_php.conf
2. Change php8_module to php_module

Once you do it, restart Laragon again, and PHP8 should work 

I couldn't install on WampServer, so I use Laragon

After installation of PHP8 on Laragon:

1. Open the file: C:\laragon\etc\apache2\mod_php.conf
2. Change php8_module to php_module

I use WampServer for PHP 7, so I can switch to PHP7 for debugging, since the xdebug doesn't support yet PHP8
