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.
See
http://www.php.net/manual/en/function.mysql-fetch-array.php
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.
