Bug Type: Feature/Change Request
Operating System: Linux 2.4
PHP Version: 4.0.6
New Comment:
popen is unidirectional on Linux, PHP can't fix that:
(from "man popen"):
The popen() function opens a process by creating a pipe,
forking, and invoking the shell. Since a pipe is by defi�
nition unidirectional, the type argument may specify only
reading or writing, not both; the resulting stream is cor�
respondingly read-only or write-only.
And the other problem can be fixed by using non-blocking IO, which PHP does not
support now AFAIK.

I'm not familiar with C, but I heard that the function "select" will help me with this
problem:
I have a fifo-pipe and want to read from it. But the scripts doesn't do anything until
I write something to the pipe. But I want to open the pipe with PHP and on the next
step, I want to write something to it.
The Problem ist, that I have to know, if there is data on the pipe or not. feof does
not help.
On the other side, the PHP-function popen should be extended for read AND write on
Linux. I heard, other plattforms can do it already.
