What's the best way to check for an Associative Array?  There is no
is_assoc() or similiar function listed in the manual (I don't think anyway).

I'm using mysql_fetch_array() and I want to foreach only the assoc. part of
the array without using mysql_fetch_assoc():

foreach ($arr as $key=>$value) { 
        echo "$key:$value";

But of course it show both the indexed array and the assoc array contents.
Is there an existing function to check this, or should I do one of these
things inside the foreach loop:

A) set $last=value and just check if $value = $lastval

B) check if the $key is just a number or just a string

C) $key += 1

?? Thanks,
