[PHP] Open read write access to process

[Lau NH]

Hi all,
   I read from the php document that I can use the popen function to open either read 
or write access to a system process, is it possible to open read and write access at 
the same time?  I tried popen with w+ but it doesn't work.  Anyone have solution to 
this?  FYI, I am using php 4.0.6 with apache 1.3.20 on redhat 7.2

[PHP] popen

Hi, is anyone know how to make popen command to read and write to a process at the 
same time?  My php script need to call linux command which requires interactive 
action, or anyone know other possible way of doing it?
