No, because AFAIK all PHP arrays are associative; there is no 
distinction between arrays & hashes as in Perl.

If you really don't want to use mysql_fetch_assoc(), you can use the 
second parameter of mysql_fetch_array():

        $arr = mysql_fetch_array($ResultHandle, MYSQL_FETCH_ASSOC);

This functions exactly like mysql_fetch_assoc(), and is available in 
PHP >= 3.0.7.


for more info.

Lastly, you _could_ just step through the array using each() in a 
loop, and use only every OTHER array entry...but this is really funky 
and you shouldn't do it this way anymore.
