ArrayObject::asort

(PHP 5 >= 5.2.0, PHP 7)

ArrayObject::asort — Sort the entries by value

Descrierea

public ArrayObject::asort ([ int $flags = SORT_REGULAR ] ) : void

Sorts the entries such that the keys maintain their correlation with the entries they are associated with. This is used mainly when sorting associative arrays where the actual element order is significant.

Parametri

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

Example #1 ArrayObject::asort() example


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

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

Exemplul de mai sus va afișa:

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

The fruits have been sorted in alphabetical order, and the key associated with each entry has been maintained.
