Exemplo #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";
}
?>
O exemplo acima irá imprimir:
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.
