XAMPP (WIndows) PHP GMP Functions

Now, in XAMPP that uses PHP 7.2.4 comment has another format:

;extension=gmp

Uncommenting this will make it work also!

According to GMP's website:

GMP's main target platforms are Unix-type systems, such as GNU/Linux, Solaris, HP-UX, Mac OS X/Darwin, BSD, AIX, etc. It also is known to work on Windows in both 32-bit and 64-bit mode.

Also try to uncomment ;extension=php_gmp.dll in php.ini

Hope it works!
