How to open two pipes to a program?

[Anon]

Hey,

I want to run a program, and both send data to it, and read data from it. It looks to me like the popen() function only lets you do one of the two, not both. Am I missing something? Is there any other way to send data to a program and read from it as well.

thanks muchly

I also have been wondering this. Apparently (if you look around this forum you'll find the same) with php4.0 you can use popen($filename, "w+") and have the ability to both read from and write to the program. However, this seems a bit sketchy and is not a supported feature of the current 4.0 release.
