ArrayIterator::ksort — Sort entries by keys

public ArrayIterator::ksort(int $flags = SORT_REGULAR): true

Sorts entries by their keys.

Si dos miembros se comparan como iguales, su orden relativo en el array oredenado será indefinido.

flags

The optional second parameter flags may be used to modify the sorting behavior using these values:

Sorting type flags:

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

Siempre devuelve true.
