ArrayObject::asort — Sort the entries by value
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.

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" ;
}
?>
以上例程会输出:
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.
