How can I sort a multidimensional array using php?

[Antivirus]

I have always done all my sorting of data within the sql query, however for once, i need to do it in php and since ive never done this in php, i'm a bit stumped, hoping someione can assist...

My array looks like this:

PHP Code:



Array
(
    [0] => Array
        (
            [groupid] => 66
            [name] => SOTE
            [description] => Lorem ipsum dolor sit amet 
            [sc_ispd] => 1
            [dateline] => 1204247554
        )

    [1] => Array
        (
            [groupid] => 88
            [name] => LOS 
            [description] => Lorem ipsum dolor sit amet
            [sc_ispd] => 0
            [dateline] => 1204779261
        )

    [2] => Array
        (
            [groupid] => 1
            [name] => MEGA
            [description] => Lorem ipsum dolor sit amet
            [sc_ispd] => 1
            [dateline] => 1202601980
        )

    [3] => Array
        (
            [groupid] => 86
            [name] => CRABS
            [description] => Lorem ipsum dolor sit amet
            [sc_ispd] => 1
            [dateline] => 1204777825
        )

) 


What I need to do is re-sort it as if doing the sort in sql like so:
ORDER BY sc_ispd DESC, dateline DESC, groupid DESC

I'm pretty sure i need to use array_multisort() to do this, but having some difficulty with it. Is it even possible to do what i am trying to do here?
