php error: The Encrypt library requires the Mcrypt extension in codeigniter

Question

I have a login and sign up form and use the encrypt library to encrypt the password.. I am using Xampp for my server and my system works correctly..

code to encrypt

Answer 1

For php 7.2 version & Ubuntu system below commands works for me -

sudo apt-get -y install gcc make autoconf libc-dev pkg-config
sudo apt-get -y install php7.2-dev
sudo apt-get -y install libmcrypt-dev
pecl install mcrypt-1.0.1

Then it will shows a message that "You should add extension for mcrypt in php.ini"

extension=mcrypt.so

and restart the apache server

service apache2 restart
or
systemctl restart apache2
