Hi,

I'm looking for a function that does almost the same as array_unique()

But it must also delete the other duplicate entry.

sample to explain:

array(
'a' => 'one',
'b' => 'one',
'c' => 'zero',
'd' => 'two'
);

I now want the result to be:

array(
'c' => 'zero',
'd' => 'two'
);

This way I will be able to do an array_diff and then see all the duplicate
entries listed.

this is to find dup. ip address for a hosting system,
displaying both accounts will make it easy to trace the amount of accounts 1
ip curruntly has.

Anybody know how to do this?

Thanks,
Allowee
