[ale] simple PHP question on proc_open

[Jerry Yu]

Thanks, Jay. I tried with 'cwd' passed in. same error, still.
Here is the exact error I am getting:
$ php j.php
PHP Warning:  proc_open(): cannot seek on a pipe in /tmp/j.php on line 11
sh: /date: No such file or directory
got it

Same script, j.php runs w/o problem with PHP/4.3 on CentOS 4.
