I was trying to find help from the PHP manual
(http://de2.php.net/manual/en/function.array-multisort.php)
but the description syntax for parameters is too complex, like
bool array_multisort ( array &$array1 [, mixed $array1_sort_order = SORT_ASC [, mixed $array1_sort_flags = SORT_REGULAR [, mixed $... ]]] )
I know that the parameters are there described, like:
array1
An array being sorted.
array1_sort_order
The order used to sort the previous array argument.
Either SORT_ASC to sort ascendingly or SORT_DESC to sort descendingly.
but what's the meaning of that description and square brackets?
