[ale] simple PHP question on proc_open

[Jay Loden]

http://ca.php.net/manual/en/function.proc-open.php

The "cwd" parameter is probably what you're looking for here:

	The initial working dir for the command. This must be an absolute 
	directory path, or NULL if you want to use the default value (the 
	working dir of the current PHP process) 

Since you're not passing a cwd param, I'd guess that it's causing it to default to someplace you don't want it to. 

Hope that helps,
