Flashdata boolean gets converted between requests

Thanks for the answer, but this is only correct for the first part.
Just tested this on my machine. Though it really gets serialized to a string, unserialize handles data types properly:

Code:

C:\Users\MatiPati\Desktop>type test.php
<?php

$a = serialize(TRUE);
var_dump($a);
var_dump(unserialize($a));

?>

C:\Users\MatiPati\Desktop>php -f test.php
string(4) "b:1;"
bool(true)
