NEWBIE

I want to directly access the the individual values in an array by using
their keys. Can this be done in PHP? The O'Reilly book I have
"Programming PHP" does not show how to do this. IT shows ways of
iterating through the array and processing keys, grabbing key/value
pairs, but I see a map-like function that will allow direct access.
