Question

I have an array that looks something like this:

Array
(
    [Erik] => Array
    ( 
        [count] => 10
        [changes] => 1
    )
    [Morten] => Array
    (
        [count] => 8
        [changes] => 1
    )
)

Now, the keys in the array are names of technicians in our Helpdesk-system. I’m trying to sort this based on number of [count] plus [changes] and then show them. I’ve tried to use usort, but then the array keys are replaced by index numbers. How can I sort this and keep the array keys?

Answer 1

You should use uasort for this.

bool uasort ( array &$array , callback
$cmp_function )

This function sorts an array such that
array indices maintain their
correlation with the array elements
they are associated with, using a
user-defined comparison function.
This is used mainly when sorting
associative arrays where the actual
element order is significant.
