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  amp  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

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
