Issue in installing php7.2-mcrypt

Question

As I'm trying to load mcrypt extension module from PHP 7.2.X version.
So I tried to make use of PECL library that is compatible to the current version of my PHP, in order to get installed and followed this link: Installing mcrypt on PHP 7.2 during installation!

These below are the result's obtained after executing certain commands on the terminal.

YYY@YYY:/var/www/html/orocrm$ sudo pecl7.2-sp install --nodeps mcrypt-snapshot
sudo: pecl7.2-sp: command not found

As I'm getting this type of Error as pecl7.2-sp: command not found

From the documentation section, it had been clearly stated that it had been deprecated and no longer will be available from the security point of view — since then, from the release version of PHP 7.2.X onward's.

But some of the project's need those dependencies, in order to carry out the required functionality as necessary. How do I need to solve the above issue?

UPDATE:

TL;DR:

I had a lot of response from the votes to the posted answer. The answers need to be triaged depending upon the OS Architecture level. Since I'm using the shared server for hosting, there are more than one projects residing over it & which are coded with the version of PHP 5.X.X, so I decided to downgrade to PHP 7.1.X that supports mcrypt extension by default in my Debian based OS.

As I already mentioned in the link while Installing mcrypt Extension on PHP 7.2, by Server Pilot community. These peoples had told a newer version of pecl-7.2 is available to install mcrypt on PHP-7.2. Unfortunately, it ended with pecl7.2-sp: command not found from the executed commands which were put up. Later the website page got an update, so the commands over there doesn't match the commands that were tried while executing.

Finally, whichever might be the solutions fit's to your OS Architecture level, Just go for it!.

OR

If the below approaches didn't yield to solve the root cause.
Alternatively, you can go for PHP 7.1.X version which supports mcrypt extension by default

You should be looking to remove mcrypt usage from your existing apps, not install it on new servers. — Narf, Jan 17 '18 at 10:52

I followed below steps to install mcrypt for PHP7.2 using PECL.

Install PECL

apt-get install php-pecl

Before installing MCRYPT you must install libmcrypt

apt-get install libmcrypt-dev libreadline-dev

Install MCRYPT 1.0.1 using PECL

pecl install mcrypt-1.0.1

After the successful installation

You should add "extension=mcrypt.so" to php.ini

Please comment below if you need any assistance. :-)

IMPORTANT !

According to php.net reference many (all) mcrypt functions have been DEPRECATED as of PHP 7.1.0. Relying on this function is highly discouraged.

On debian, for step 1, use `apt-get install php-pear` to use PECL command. – Vincent Decaux Feb 22 '18 at 09:18

php-pear is also used for Ubuntu – Simon Hayter Apr 07 '18 at 15:47

@PraneethNidarshan it didn't work. Because as i installed using the above command line, it went with php5.3 packages and i finally ended up overwrite my php7.2 with php 5.3 – The One Apr 23 '18 at 01:56

Mcrypt PECL extenstion

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

When you are shown the prompt

 libmcrypt prefix? [autodetect] :

Press [Enter] to autodetect.

After success installing mcrypt trought pecl, you should add mcrypt.so extension to php.ini.

The output will look like this:

...
Build process completed successfully
Installing '/usr/lib/php/20170718/mcrypt.so'    ---->   this is our path to mcrypt extension lib
install ok: channel://pecl.php.net/mcrypt-1.0.1
configuration option "php_ini" is not set to php.ini location
You should add "extension=mcrypt.so" to php.ini

Grab installing path and add to cli and apache2 php.ini configuration.

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

Verify that the extension was installed

Run command:

php -i | grep "mcrypt"

The output will look like this:

/etc/php/7.2/cli/conf.d/mcrypt.ini
Registered Stream Filters => zlib.*, string.rot13, string.toupper, string.tolower, string.strip_tags, convert.*, consumed, dechunk, convert.iconv.*, mcrypt.*, mdecrypt.*
mcrypt
mcrypt support => enabled
mcrypt_filter support => enabled
mcrypt.algorithms_dir => no value => no value
mcrypt.modes_dir => no value => no value

@pragnesh-karia although it is possible to install that library on Windows, it will save you A LOT of trouble if you use a linux Vagrant machine — Alberto, Aug 06 '18 at 09:56
This answer it's ok, but I have to install the `php-dev` package also. — Tuxman, Nov 28 '18 at 17:11
@PrafullaKumarSahu You need php-pear, php-dev, and libmcrypt-dev packages installed to run these commands. — Arda, Jul 12 '19 at 22:06
`Installing '/usr/lib/php/20170718/mcrypt.so'` I have multiple PHP versions on my machine. My current PHP CLI version is 7.2 but when I install mcrypt, it is installed for PHP 5.6. How do I install it for 7.2? — Ejaz, Nov 13 '19 at 05:45

@praneeth-nidarshan has covered mostly all the steps, except some:

Check if you have pear installed (or install):

$ sudo apt-get install php-pear

Install, if isn't already installed, php7.2-dev, in order to avoid the error:

sh: phpize: not found

ERROR: `phpize’ failed

$ sudo apt-get install php7.2-dev

Install mcrypt using pecl:

$ sudo pecl install mcrypt-1.0.1

Add the extention extension=mcrypt.so to your php.ini configuration file; if you don't know where it is, search with:

$ sudo php -i | grep 'Configuration File'

sudo apt-get install php-pear php7.x-dev

x is your php version like 7.2 the php7.2-dev

apt-get install libmcrypt-dev libreadline-dev
pecl install mcrypt-1.0.1

then add "extension=mcrypt.so" in "/etc/php/7.2/apache2/php.ini"

here php.ini is depends on your php installatio and apache used php version.

As an alternative, you can install 7.1 version of mcrypt and create a symbolic link to it:

Install php7.1-mcrypt:

sudo apt install php7.1-mcrypt

Create a symbolic link:

sudo ln -s /etc/php/7.1/mods-available/mcrypt.ini /etc/php/7.2/mods-available

After enabling mcrypt by sudo phpenmod mcrypt, it gets available.

After hours of research the bit I needed was the last paragraph! in my case it was: `sudo phpenmod -v 7.3 mcrypt` – cdsaenz Jan 10 '21 at 23:13
