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.

For some unknown reason the OP specifically does not want to use
mysql_fetch_assoc()!

RE: [PHP] Check for Associative Array
Ya, except I want the whole array to exist (index and assoc. array), not
just the assoc. array. So, for the time being, I'll just do this:
foreach ($arr as $key=>$value) {
if ( !is_int($key) ) { echo "$key:$value"; }
}
What is HTH ??

Try this:
while($row = mysql_fetch_assoc($result)) {
// code here
}
This way, the resulting array will ONLY be associative.
HTH!

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,
