ArrayIterator::ksort
Sort entries by keys
Description
public true ArrayIterator::ksort(int $flags = SORT_REGULAR)
Note:
If two members compare as equal, they retain their original order.
Prior to PHP 8.0.0, their relative order in the sorted array was undefined.
Parameters
-
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
Return Values
Always returns true.
