Re: Searchingfor text within a string

You are absolutely right, sorry for doubting you. I rewrote the code and it looks like this: <? passthru("ping -c 1 $address", $result); if ($result == 0){ echo "Green Light\n"; } else { echo "Red Light\n"; } ?> I created a simple form that passes the $address variable to this script. The results were a bit weird, The output of the ping command is also displayed in the browser. How can I get rid of this? If you replace the $address variable above with a valid, or invalid, address it works great. I only get the weird output when I use the form.
