Quizplus · Accepted Answer

The krsort() function performs a reverse sort on an associative array by keys while maintaining the existing keys. This means that the key-value associations will not be lost, only the order of the keys will be reversed.

The ksort() function also sorts an associative array by key, but in ascending order (not reverse).

The uk_sort() function is not a valid PHP function.

The sort() function is used to sort an array in ascending order, but it does not maintain the key-value associations.
