Using the Key Value Pair store

To use the key-value pair storage helper, simply reference the $keyval object that has been instantiated.

Interface

→get($name)
Returns the value of the key specified via $name. This value should be a string.

→set($name, $value)
Sets the value of the key specified via $name to the data stored in $value. The value being set should be a string.

→destroy($name)
Deletes the key specified via $name.

Extending

By default, Interchange includes a driver for both Memcache and Memcached (PECL extensions), as well as a JSON-based raw file store. The driver used can be changed by setting the IXG_KV_STORAGE.

Creating a new driver

Create a PHP file in the /helpers/keyval/ directory of your installation. It should be named in the style of your_drivers_name.php. In this file, create a class named your_drivers_name_driver. This class should implement the above interface. You are free to use constructors, though destructors may prove to be troublesome.

To activate your driver, simply reference it with IXG_KV_STORAGE by setting its value to your_drivers_name.
