To clarify the note above Example #1, the function appears to cast the elements to strings for
comparison and then return the type of the first unique element encountered.
<?php
$input = array(0, 2, "2", 3, "9", 9);
$result = array_unique($input);
var_dump($result);
?>
array(4) {
[0]=>
int(0)
[1]=>
int(2)
[3]=>
int(3)
[4]=>
string(1) "9"
}
