[SOLVED] Sorting an array

[unkwntech]

I have a function that I wrote some time ago to sort an array based on the value of a key, for example in this array:

$error['0']['level'] = '0';
$error['1']['level'] = '1';
$error['2']['level'] = '1';
$error['3']['level'] = '0';

could be sorted to 0312.

 

I know that must be a built-in PHP function to do this, and it is probobly faster then what I wrote.

sort, usort

Looks like usort() is what I'm looking for.  sort() only sorts my indexes.

Thanks.
