The streamWrapper class
Introduction
Allows you to implement your own protocol handlers and streams for use with all the other filesystem functions (such as fopen(), fread() etc.).
Note:
This is NOT a real class, only a prototype of how a class defining its own protocol should be.
Note:
Implementing the methods in other ways then described here can lead to undefined behaviour.
An instance of this class is initialized as soon as a stream function tries to access the protocol it is associated with.
Class synopsis
Properties
- resource context
-
The current context, or NULL if no context was passed to the caller function.
Use the stream_context_get_options() to parse the context.
Note:
This property must be public so PHP can populate it with the actual context resource.
