streamWrapper::stream_write — Write to stream
This method is called in response to fwrite().
Note: Remember to update the current position of the stream by number of bytes that were successfully written.
Should be stored into the underlying stream.
Note: If there is not enough room in the underlying stream, store as much as possible.
Should return the number of bytes that were successfully stored, or 0 if none could be stored.
Emits E_WARNING if call to this method fails (i.e. not implemented).
Note: If the return value is greater the length of data, E_WARNING will be emitted and the return value will truncated to its length.
