It is best not to use mcrypt, it is abandonware, has not been updated in years and does not support standard PKCS#7 (née PKCS#5) padding, only non-standard null padding that can't even be used with binary data. Instead consider using [defuse](https://github.com/defuse/php-encryption), it is being maintained and is correct. — zaph, May 12 '16 at 13:10

You will see a group of Dynamic Extensions. like this:

;;;;;;;;;;;;;;;;;;;;;;
; Dynamic Extensions ;
;;;;;;;;;;;;;;;;;;;;;;

; If you wish to have an extension loaded automatically, use the following
; syntax:
;
;extension=modulename.extension

add your extension below this without ;

yes done it and one more thing to go 1) Could not save the file “/etc/php5/apache2/php.ini”.You do not have the permissions necessary to save the file. Please check that you typed the location correctly and try again what should be the workaround for the above error? – Shekhar Reddy May 12 '16 at 11:45

You have to open this file a root/administrator, which OS are you using? – Meathanjay May 12 '16 at 11:48
Use this command: `sudo gedit /path/to/php.ini`. the php.ini will be open in gedit (default editor) and you will be able to save the changes. – Meathanjay May 12 '16 at 11:53

Add this line to all other extensions:

;extension=some.so
extension=thing.so
extension=mcrypt.so

Also, don't forget to reboot web server after that to make it work.
