Behavior is correct as you can see below:
marcus@zaphod /usr/src/php5 $ php -r 'class FOO{}$o=new
FOO;var_dump(serialize($o));'
string(14) "O:3:"FOO":0:{}"
marcus@zaphod /usr/src/php5 $ php -r
'$o=unserialize("O:3:\"FOO\":0:{}");var_dump($o);'
object(__PHP_Incomplete_Class)#1 (1) {
["__PHP_Incomplete_Class_Name"]=>
string(3) "foo"
}
marcus@zaphod /usr/src/php5 $ php -r 'class
FOO{}$o=unserialize("O:3:\"FOO\":0:{}");var_dump($o);'
object(FOO)#1 (0) {
}

Ok, you say

> stored in lowercase form internally.
but why does the __autoload() function not convert to
lowercase if i make an instance like "new myTestWithUpper"?
this is a _little_ bit confusing :-(

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to
report
a bug at http://bugs.php.net/how-to-report.php
In php class names are not case sensitive and are stored in
lowercase form internally.

A short sample script
STEP One:
function __autoload($sClass) {
echo $sClass."<br>";
}
ini_set(
'unserialize_callback_func',
'__autoload'
);
class myTestWithUpper {
public $test;
protected function __sleep() {
return array('test');
}
}
file_put_contents(
"./test.dat",
serialize(
new myTestWithUpper()
)
);
STEP Two:
unserialize(
file_get_contents ("./test.dat")
);

Description:
------------
I use the __autoload($sClass) feature, and the $sClass
names are always transmitted as is. With upper and
lower characters.
But when i cache a class with serialize and try
to unserialize, the $sClass names are only lowercase.
