openlss/lib-stream-wrapper

Simple library that implements PHP's stream wrapper with simpler extension for rapid wrapper development., _(*1)

The below interface shows the usage of this library., _(*2)

There is also an example located at Example/MyFS.php this is used to test the library., _(*3)

NOTE: Only needed methods need to be extended. The interface is satisfied purely by extending. This is done to support PHP's allowance of unsupported features. Thus, by default everything is unsupported and you can define what needs to be supported., _(*4)
