Is this really true?

I can run a number of console applications via proc_open() without encountering 
blocking on win32.  

However, I have encountered a number of applications that will cause PHP hang 
on 
fread() until the process closes (regardless of whether or not the buffer has 
filled).

This needs to either be categorized as a bug, or the documentation needs to be 
updated 
to explain this unexpected behavior on win32.  

PHP 5.4.3/Win7x64.

Essentially, non-blocking streams don't exist in win32 PHP.

They work fine for non-win32, so maybe this should become a feature 
request.

>From reading the MSDN sites regarding non-blocking/blocking, it seems 
that a completely different mechanism for file handling needs to be 
used.

Other scripting languages have solved this issue in a different fashion, 
using an additional thread to process the stream.

Same problem here...

If we use proc_open and the output (pipes[1]) is greater than 2kb, 
the application just gets stuck!

I don't have any idea why, but it is never terminated, unless we do 
an FREAD of FGETS at the pipe[1].

But we can't do the FGETS if we don't know if there is content to be 
read. There is when stream_set_blocking should save the day.. But it 
doesn't work! :(

I tested this on PHP 5.3 (on Linux) and duplicated the error that the print_r 
command shows blocking as true. HOWEVER, the stream does not block when 
actually tested... a simple test script can be created by adding a line and 
slightly modifying the scripts found at:

If it exists below 5.3, the version must state it! Do NOT touch it 
again.

Only worry about 5.3+
