Want to read a key from the registry with php

Ok, thanks. But one more thing: Is it then so that it's not possible to get any information about the client's system, like the Mac address or the PC name? I came across this code on the internet:

$MAC = exec('getmac');
$MAC = strtok($MAC, ' ');
echo "Mac address is $MAC";

I didn't get it to work. Again got the HTTP ERROR 500, while the the error_reporting didn't work neither.

No, you can't get those two either. The MAC address is only available at a very low level in the system and it only tells you the hardware on the other end of the ethernet cable. The computer name is not something that gets sent over the internet.

Ok. Thank you.
