Linux Help · Answer

In Ubuntu 18.10, mcrypt php module is deprecated.So it isn't available by default.But you could install it using pecl.To install php-mcrypt module,there are three modules  that you need to install in advance.
apt install php-pear php-dev libmcrypt-dev -y
pecl channel-update pecl.php.net
Install the new version of mcrypt that is mentioned in the pecl.php.netIn my case,the version of mcrypt is like
pecl install mcrypt-1.0.2
To Check the mcrypt module
php -m | grep 'mcrypt'
If it results mcrypt, thus mcrypt module is successfully installed.
