sorting help

[peri]

I've got a 2d array that looks like this:

 

array(3) {

  ["5F"]=>

  array(6) {

    ["pid"]=>

    int(234)

    ["name"]=>

    string(7) "n/a n/a"   

  }

 

  ["52C"]=>

  array(6) {

    ["pid"]=>

    int(42)

    ["name"]=>

    string(7) "n/a n/a"   

  }

 

  ["3F"]=>

  array(6) {

    ["pid"]=>

    int(4452)

    ["name"]=>

    string(7) "n/a n/a"   

  }

}

 

How do I sort it so that they keys appear in the order: 3F, 5F, 52C?
