Value from remote server

[Digimatt]

I am using the file() function to run a script on a remote server. The script on the remote server needs to return a value to the current server.

$listings = implode('', file("http://www.remoteserver.com/logs/foobarlog.php?name1=$value1&name2=$value2"));
	echo $listings;

I would like to get a value back from the remote server. How do I tell the remote server to return the value?

I would prefer to have the remote script set a cookie. That script is the one that would need to read the cookie, so it should work, but the remote script won't set the cookie.

Okay, I got it. Let's say that in the remote script I multiply name1 and name2.

$name3 = $name1 * $name2;

Then I just echo $name3.

echo $name3;

then in the local script, $foo holds the echoed value.

$foo = $name3;

I can use $foo however I want.
