Need help sorting a 2D array!

[Anon]

I'm killing brain cells trying to sort a 2D array that looks something like this:

$array[0] = array("fname"=>"Jon", "lname"=>"Doe");
$array[1] = array("fname"=>"Jane", "lname"=>"Anon");

I would want $array[0] to return Jane Anon rather than Jon Doe... Anybody have a suggestion?

Can you do this with array_multisort?

I cannot find any reference in the php3 manual to the function array_multisort... What is the syntax to use it?

It is specific to php4. Check the news file. It is not documented yet, but here is the header info:

bool array_multisort(array ar1 [, SORT_ASC|SORT_DESC] [, array ar2 [, SORT_ASC|SORT_DESC], ...])
Sort multiple arrays at once similar to how ORDER BY clause works in SQL

If you are using php3, you'll have to write or find a sort routine.

looks like it's time to upgrade to php4... Thanks for the help, this should work beautifully..
