Sorttype is optional. Specifies how to arrange the values of an array. Possible values:
SORT_REGULAR-default. Process with their original type (without changing the type ).
SORT_NUMERIC-process the value as a number
SORT_STRING-process the value as a string
SORT_LOCALE_STRING-process the value as a string based on local settings *.

Array ([0] => Cat [1] => Dog [2] => Horse)
