PHP File Array: Store and retrieve values from files as arrays

This class can store and retrieve values from files as if they were arrays.

It provides an ArrayAccess interface so you can store and retrieve values of arbitrary types in files.

Each array entry value is encoded with base64 algorithm and stored with a line break to distinguish from other entries.

The class reads a given number of lines according to the position of the array entry it needs to read and decode from the array file.
