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.


This function has no parameters.

Return Values

No value is returned.


Example #1 ArrayObject::asort example

= array("d" => "lemon""a" => "orange""b" => "banana""c" => "apple");
$fruitArrayObject = new ArrayObject($fruits);

foreach (
$fruitArrayObject as $key => $val) {
"$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.
