File exchange Protocol can be used to store and retrieve files in a remote repository server using HTTP. It can access a remote server using HTTP requests with authentication to protect the access to the remote files. The class can perform requests to create, write, read, and delete remote files. It can also create, list, and delete directories. It implements a stream wrapper interface to make it possible to access the remote files with PHP functions like fopen('fep://...') and other PHP file and directory manipulation functions. You can also apply a Stream Wrapper that allows you to mount a remote filesystem.
MS-Excel Stream Handler is a class that implements a stream handler interface for reading and writing Microsoft Excel spreadsheet files in the XLS format.
