ArrayObject::ksort

(PHP 5 >= 5.2.0, PHP 7)

ArrayObject::ksortSort the entries by key

Beschreibung

public ArrayObject::ksort ( int $flags = SORT_REGULAR ) : void

Sorts the entries by key, maintaining key to entry correlations. This is useful mainly for associative arrays.

Parameter-Liste

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

R├╝ckgabewerte

Beispiele

Beispiel #1 ArrayObject::ksort() example

<?php
$fruits 
= array("d" => "lemon""a" => "orange""b" => "banana""c" => "apple");
$fruitArrayObject = new ArrayObject($fruits);
$fruitArrayObject->ksort();

foreach (
$fruitArrayObject as $key => $val) {
    echo 
"$key = $val\n";
}
 
?>

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

a = orange
b = banana
c = apple
d = lemon
