Ah, yeah, my example was just a way to pass the path on to the script - 
not determine the path automatically. If you want to determine the path 
automatically, the only way I can see that you could do that would be to 
run two separate scripts (including the method I used above.)

Something like this:
$DYNAMICPATH = find / -name php | grep php $DYNAMICPATH

The idea being that the file would find the path to php 
on that system, then pass that path on to the script that will be 
executing the php commands.

Now... don't get me wrong. I'm not an expert script writer or anything. 
I haven't tested these scripts. However, the logic behind them is still 
valid, and should work if properly executed. (with the correct shell 
commands, etc)
