[PHP-DEV] [Sorta OT] Mystery zcontext?

[John Coggeshall]

I was digging around the ext/standard today and I wanted to do something
with the file access stuff, however I'm a bit lost on something... I'd
appreciate it if someone could explain this (as it's basically
undocumented).

What is the fourth parameter for the fopen() function? It's listed as a
resource, and there is some mention of using callbacks, etc But I
can't pin it down looking at the code... Anyone care to comment what the
zcontext parameter does? 

John

Hi John,

It's for some funky stuff that won't really come into it's own until
version 5 of PHP.

ATM, you can use stream_context_XXX family of functions to do:

o Set notification callbacks.  These can be used to implement progress
bars for event driven applications.

o Set parameters for the various URL wrappers. For http you can set the
user-agent header.

The context can be shared between multiple streams, and once the curl
library has enough hooks, the curlwrappers will use the context to do
things like store session cookies.

There is a documentation bug about this that might have a little bit
more info.
