ArrayObject::asort

(PHP 5 >= 5.2.0, PHP 7)

Sort the entries by value

public void ArrayObject::asort ( 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.

No value is returned.

Examples:

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";
}
?>

The above example will output:

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.
