Yes, it is reproducible:
C:\Dokumente und
Einstellungen\nohn_s\Desktop\php5.1-win32-200510031830>php test.php
object(__PHP_Incomplete_Class)#1 (2) {
["__PHP_Incomplete_Class_Name"]=>
string(3) "bar"
["someProp"]=>
int(2)
}
Fatal error: main(): The script tried to execute a method or access a
property of an incomplete object. Please ensure that the class
definition "bar" of the object you are trying to operate on was loaded
_before_ unserialize() gets called or provide a __autoload() function
to load the class definition in C:\Dokumente und

Can you reproduce with 5.1-dev?

Reopening this bug. Could reproduce it with PHP 5.0.5 on WinXP:
>type test.php
<?php
class foo{function someFunc(){} var$someProp=2;}$a=serialize(new
foo());$b=str_replace('foo','bar',$a);var_dum
p($c = unserialize($b));$c->someFunc();
?>
>php test.php
object(__PHP_Incomplete_Class)#1 (2) {
["__PHP_Incomplete_Class_Name"]=>
string(3) "bar"
["someProp"]=>
int(2)
}
Fatal error: main(): The script tried to execute a method or access a
property of an incomplete object. Please ensure that the class
definition "bar" of the object you are trying to operate on was loaded
_before_ unserialize() gets called or provide a __autoload() function

This bug has been fixed in CVS.
Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
Thank you for the report, and for helping us make PHP better.

Hmm.. I really don't understand why incomplete_class_message() looks
for class_name in EG(This), while class_name is property of the object,
which could be easily passed to incomplete_class_message().
So, this patch should probably fix it:

Comments are welcome.

Description:
------------
The idea is that when an object is unserialized and the class
definition is still not loaded then it is converted to
__PHP_Incomplete_Class class. From the dump of the actual result one
can see that the name is stored in a member variable
__PHP_Incomplete_Class_Name. So far everything looks ok. But when one
tries to execute a method on incomplete class object it leads to a
fatal error. This is also correct. However the name of the class is
"unknown" is the message. This is not correct and the example works
with PHP 4.3.8(cli). However does not work with current HEAD (probably
not with the PHP_5 branch).
One additional thing is that the message is misleading. A serialized
object may not come always from a session but can be loaded from a file
by the user or ,like in my case where I found the error, from a socket.
Thanks
Reproduce code:
---------------
php -r 'class foo{function someFunc(){} var
$someProp=2;}$a=serialize(new foo());$b=str_replace('foo','bar',
$a);var_dump($c = unserialize($b));$c->someFunc();'
Expected result:
----------------
object(__PHP_Incomplete_Class)#1 (2) {
["__PHP_Incomplete_Class_Name"]=>
string(3) "bar"
["someProp"]=>
int(2)
}
Fatal error: Unknown: The script tried to execute a method or access a
property of an incomplete object. Please ensure that the class
definition <b>bar</b> of the object you are trying to operate on was
loaded _before_ the session was started in Command line code on line 1
Actual result:
--------------
object(__PHP_Incomplete_Class)#1 (2) {
["__PHP_Incomplete_Class_Name"]=>
string(3) "bar"
["someProp"]=>
int(2)
}
Fatal error: Unknown: The script tried to execute a method or access a
