Description:
------------
---
From manual page:
http://www.php.net/function.array-unique#refsect1-function.array-unique-examples
---
In the example code int(4) and string("3") are both the first and last
versions of those values encountered!
<?php
$input = array(4, "4", "3", 4, 3, "3");
^ ^^^ ^ ^^^
$result = array_unique($input);
var_dump($result);
?>
It would be better written as
<?php
$input = array(4, "4", "3", "4", 3, 3);
$result = array_unique($input);
var_dump($result);
?>
or something else that shows it's the _first_ value that determines the
type, not the last.
