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.)

There is no installation needed to use these functions; they are part of the PHP core.

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.
