Accessing Remote Files

I have a php file that I use to do some calculations and print out a variable. I have a script that works great in php, but i want to provide this service to alot of people and not everyone uses PHP.

//PHP code
function MyFunction() {
$lnk = fopen("http://www.programmers-unlimited.com/MyRemoteFile.php","r");
$buffer = fgets($lnk, 4096);
fclose ($lnk);
return $buffer;
}

//END PHP code

This will get the data returned by my remote php page. How can I do this in ASP ?
