Getting 1 word from an array element

[Anon]

Hi!

Here's a little of the code (sorry, i'm new to php!):

unset($stuff);
exec("arp -a $REMOTE_ADDR",$stuff);
for ($i = "0"; $i <= count($stuff); $i++){echo "<p>Element: $stuff[$i]";}

This seems to create an array element ($stuff[]) out of each line of the output of "arp -a $REMOTE_ADDR". I can echo each element to a page just fine, but my goal is to be able to echo ONLY the MAC address, rather than the entire line. Any ideas on how I might do this?

Thanks for your help!

Would $piece = explode(" ",stuff[$i]) and then checking each $piece[] work for you?

Cool! This seems to work fine...now i can echo a certain element in the pieces array. This will work as long as I know that the data I need will always be in that position. Thanks a bunch...this really got me past a big road block.

Take it easy..
