/**
* Sorts the elements in an array.
*
* You can use your own comparator for element comparison, but the default comparators, such as
* `CComparator::ORDER_ASC` and `CComparator::ORDER_DESC`, have got you covered when sorting scalar values, such as
* `string`, `int`, `float`, and `bool` in the ascending or descending order respectively. And the default
* comparators are smart enough to know how to compare objects of those classes that conform to the
* IEqualityAndOrder interface (static or not), including CUStringObject, CArrayObject, CMapObject, CTime etc. See
* the [CComparator](CComparator.html) class for more on this.
*
* @param callable $comparator **OPTIONAL. Default is** `CComparator::ORDER_ASC`. The function or method to be
* used for the comparison of any two elements. If this parameter is provided, the comparator should take two
* parameters, which are the two elements being compared, and return `-1` if the first element needs to go before
* the second element in the sorted array, `1` if the other way around, and `0` if the two elements are equal.
*
* @return void
