Sorting multidim array and keeping associations

Best groupmember, I have an multidim array that looks something like this: [40] => [1]=32, [2]=>55, ["total"]=>87 [22] => [8]=2, [7]=>105, ["total"]=>107 [142] => [2]=3, [7]=>8, ["total"]=>11 I want to sort this array according to the "total" and still keep the acc. with the basekey. I know I can easily do this by writing an function myself. But are there any built in functions for this? I have looked at usort, uksort and more, but they do not seem to solve my problem. - Best Of Times /Peter
