On Ubuntu 13.10 you have to install this extension first (PHP 5.5.3):

   apt-get install php5-json

(Don't forget to restart web server.)

On one server I use (FreeBSD 6.3; PHP 5.2.6 as module in Apache 2.2.10), PHP was compiled with the '--disable-all' configuration option. Consequently, there exists a secondary configuration file -- /usr/local/php5/etc/extensions.ini -- in which the line

; extension=json.so

must be uncommented (delete the semicolon) and Apache restarted for these functions to be available.

On RHEL5/CentOS5 add the EPEL repository (http://fedoraproject.org/wiki/EPEL).

After that, installation is as simple as:

    sudo yum install php-pecl-json
