Sort an array

Syntax

sort ( array &$array [, int $sort_flags = SORT_REGULAR ] ) : bool

sort_flags

Modify the sorting behavior.

SORT_REGULAR compare items normally; the details are described in the comparison operators section
SORT_NUMERIC compare items numerically
SORT_STRING compare items as strings
SORT_LOCALE_STRING compare items as strings, based on the current locale. It uses the locale, which can be changed using setlocale()
SORT_NATURAL compare items as strings using "natural ordering" like natsort()
SORT_FLAG_CASE can be combined (bitwise OR) with SORT_STRING or SORT_NATURAL to sort strings case-insensitively

Return
