Answer 1

Sure, you can pass variables the same way as you do on the commandline. Just append them. For safety, escape the variable before you do so:

exec('./test.sh ' . escapeshellarg($path));

Then, in your shell sccript, this is available as $1 :

#!/bin/sh
echo $1

Answer 2

There are several ways to do that:

Pass as argument to the script:

<?php
exec("./test.sh ". escapeshellarg($path));

And from the script:

#!/bin/bash
echo "Path is $1"

Pass through the environment

<?php
putenv('PATH='. $path);
exec("./test.sh");

And from the script:

#!/bin/bash
echo "$PATH"

On the standard input

I guess there is a way to do this too, but I wasn't able to find out how on a quick search.
