How to add / install JSON support to PHP on CentOS in 10 Steps

We are using staging server inside our organization (CentOS) to test the applications that we work on. We heavily use
AMFPHP based PHP services to do communication between business logic and client front end in flash.

Team requested to have native JSON support for PHP and I found a very simple way to do it as following:

Login to shell prompt with user credentials (which allows you to install stuff on server).
Execute command yum update “*php*”
This should update all PHP related components to the latest version. (Assuming you installed yum etc., on CentOS)
Once done that, You will require to install Pear based JSON support by following command.
pecl install json
This will install JSON, simply wait and cross your fingers! If it says OK in last 2 lines, everything is fine so far.
You will also require to enable JSON support in php.ini
Smart way to do that is, create a new file in /etc/php.d/ called
json.ini
The file should contain this line: extension=json.so
Finally, restart the HTTP (Apache) Server by command: service httpd restart

Done! Here is the all keyboard actions together, after you logged in:

yum update “*php*”

pecl install json

cd /etc/php.d/

echo “extension=json.so” >> json.ini

service httpd restart
