PHP: ArrayObject::asort - Manual

(PHP 5 >= 5.2.0, PHP 7, PHP 8)

ArrayObject::asort — Sort the entries by value

Description

This is used mainly when sorting associative arrays where the actual element order is significant.

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.

Return Values

Always returns true.

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

$fruitArrayObject->asort();

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

c = apple
b = banana
