#26762 [Bgs->Opn]: unserialize() produces lowercase classnames

New Comment:
Actually unserialized lowercases the classname. But we store the
lowercased classname only in the hashtable while we preserver the
casing for its real name.

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.
