If an object implements a __toString() magic method, then it can work ...


<?php
class randomizer {
	public function __toString() {
		return (string)mt_rand();
	}
}

$randomizer = new randomizer;
$array = array (
	"$randomizer" => 'First',
	"$randomizer" => 'Second',
	"$randomizer" => 'Third',
	"$randomizer" => 'Fourth',
);

print_r($array);
?>

outputs ...

Array
(
    [1365443950] => First
    [1235256771] => Second
    [520059180] => Third
    [486985268] => Fourth
)
