Getting Results from function

I am using the Snoopy class to submit to a form and receive the results. I am then parsing the hidden form fields <input type="hidden" name="butterfinger" value="one"> <input type="hidden" name="snickers" value="good"> down to butterfinger="one"; snickers="good"; Here is the call to the function: if ($go){ $string=_stripform($snoopy->results); //do some additional parsing here $string2= ereg_replace ("<input type=\"hidden\" name=\"", " $", $string); $string3= ereg_replace ("\" value", "", $string2); $string4= ereg_replace (">", ";\r\n", $string3); echo $string4;} when I echo $string4, I get the correct results but they aren't parsed by php. The variables list on the page as a text. I need the variables and I don't understand how I can access the variables as in: print $butterfinger; Thanks in advance Kevin
