in response to guest3a83ae, the stream_eof() method is something you must implement for user wrappers otherwise the feof() function won’t operate correctly on streams created from that wrapper. My personal feeling is that the world doesn’t need feof(), but I have to live with the fact that the world uses feof() anyway, so this method is therefore necessary to make things work for them.

Wez, correct me if I’m wrong but you talked about feof() having 'no place' in streams and thus you should use stream_select() and fread() to determine if the socket is closed rather than feof(). Yet on slide 43 you have:

function stream_eof(){

return feof($this->fp);

}

Is that due to brevity or is this just an older presentation?

All in all, a good slide show.
