<?php
// Comparison function
function cmp($a, $b) {
if ($a == $b) {
return 0;
}
return ($a < $b) ? -1 : 1;
}
// Array to be sorted
$array = array('a' => 4, 'b' => 8, 'c' => -1, 'd' => -9, 'e' => 2, 'f' => 5, 'g' => 3, 'h' => -4);
$arrayObject = new ArrayObject($array);
var_dump($arrayObject);
// Sort and print the resulting array
$arrayObject->uasort('cmp');
var_dump($arrayObject);
?>
The above example will output:
object(ArrayObject)#1 (1) {
["storage":"ArrayObject":private]=>
array(8) {
["a"]=>
int(4)
["b"]=>
int(8)
["c"]=>
int(-1)
["d"]=>
int(-9)
["e"]=>
int(2)
["f"]=>
int(5)
["g"]=>
int(3)
["h"]=>
int(-4)
}
}
object(ArrayObject)#1 (1) {
["storage":"ArrayObject":private]=>
array(8) {
["d"]=>

["e"]=>
int(2)
["g"]=>
