How to do this with Amazon Linux 1?

how about windows version

For those, who faced with ERROR: 'phpize' failed issue, you may install it with sudo sudo apt-get install php7.2-dev command.

Hi,

is there a 'mcrypt' for PHP 7.2 on Windows?

I found that the lastest version of PHP which cames with these Dll´s ('libmcrypt.dll' and '/ext/php_mcrypt.dll') is php-5.2.9-Win32-VC6-x86.zip

I tried to copy these files and also call it on the 'C:\PROGRAM FILES\PHP\V7.2\PHP.INI' as the article 'https://www.myoddweb.com/2010/11/18/install-mcrypt-for-php-on-windows/' but no sucess...

I found some 'tricks' to put that module work on Linux PHP v7.2:

https://stackoverflow.com/questions/48275494/issue-in-installing-php7-2-mcrypt/50079503#50079503

Another trick but for php 5.8:

https://github.com/ewwink/windows-php-mcrypt-dependency

Thanks! It works!

add:
sudo apt-get install php7.2-dev

Thanks! One questions: What if we are using Ngnix instead of Apache in this step: sudo bash -c "echo extension=/usr/lib/php/20170718/mcrypt.so > /etc/php/7.2/apache2/conf.d/mcrypt.ini"

Thanks!

sudo bash -c "echo extension=/usr/lib/php/20170718/mcrypt.so > /etc/php/7.2/apache2/conf.d/mcrypt.ini"

I did

sudo bash -c "echo extension=/usr/lib/php/20170718/mcrypt.so > /etc/php/7.3/mods-available/mcrypt.ini"
sudo phpenmod mcrypt # (add symlinks in /etc/php/7.3/cli/conf.d/ and /etc/php/7.3/apache2/conf.d/)

you have multiple php versions installed, i see you are having trouble and running any commands you googled. I had a coworker who did the same thing. He figured out how to make his cli and normal php the same version and then got this working... please follow my next post

i'd remove everything then do the following:
https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-ubuntu-18-04
and then
https://lukasmestan.com/install-mcrypt-extension-in-php7-2/

when you get phpize error
Q: I see error message: ERROR: 'phpize' failed
A: install php7.2-dev with apt-get install php7.2-dev

@dave-lw, i installed it form source code (gist)

yeah the problem is with your php though, you have several versions installed and it is causing problems. I gave you the solution.

For Xampp you can look for the DLL links here: https://pecl.php.net/package/mcrypt

E.g. for my Xampp with PHP 7.3.12, I downloaded 7.3 Thread Safe (TS) x64 from here: https://pecl.php.net/package/mcrypt/1.0.3/windows

I dropped the DLL in C:\xampp_7.3.12\php\ext\, and added the line extension=php_mcrypt.dll to php.ini

Reminder: you are not supposed to use mcrypt in production.

You saved my day

For PHP 7.3 this is
sudo pecl install mcrypt-1.0.2

How to confirm mcrypt is insalled ?

php -m lists your active modules.

For Windows Users

• Check in your PHP Info if your PHP is 32bit (x86) or 64bit (x64)
  
• Now visit: https://pecl.php.net/package/mcrypt/1.0.3/windows and download the appropriate version for your PHP's version and the architecture.
• Again in your PHP info page, search for var: extension_dir and open the directory.
  
• Unzip the file you downloaded from the above url.
• Open your XAMPP's or MAMP's php.ini file. In case you don't know where is it, you can find it from your php info page again:
  
• Inside the php.ini file, find where the extensions are loaded. It should be lines like: extension=php_curl.dll etc.
• Add a new line: extension=php_mcrypt.dll and save the file changes.
• Now restart XAMPP/MAMPP or apache in general.

It's ready!

You should be able to see something like the following:
