How to enable mcrypt php extension on xampp linux

I have installed xampp on my ubuntu machine through the installer having php version 7.2.4

Recently I need to enable Mcrypt PHP extension but I did not find it on php.ini file.

I have tried to modify php.ini following ways but it is not working

extension=mcrypt

What would be the easiest way to enable the mcrypt php extesion on xampp linux?

Answer

I have installed a PHP 7.0 version of xampp linux separately and found mcrypt available there but it is not available from PHP 7.1.

Its working well now with PHP 7.0 version without any prior change
