PEAR2_Cache_SHM by boenrobot
Allows you to share data across requests as long as the PHP process is running. One of APC, APCu or WinCache is required to accomplish this, with other extensions being potentially pluggable as adapters.
Install
If you have Pyrus, without downloading anything:
pyrus install -o PEAR2_Cache_SHM-alpha
And in your PHP, load it with any PSR-0 compatible autoloader (e.g. PEAR2_Autoload).
Alternatively, if you download the PHAR archive from this page, you can just include it, like:
<?php require_once 'PEAR2_Cache_SHM-0.2.0.phar'; //Rest of your code
See the page in the project's wiki for details and other ways of installation.
