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

Actually this is expected behavior. We explicitly decided to have $this
being readonly because of interna problems with the new engine.

Take a look at PEAR::DB for an example of using a factory method (i.e.:
  $foo = DB::connect($uri);  )

For background on why support for reassigning $this was dropped, take a
look at http://news.php.net ( php.internals mailing list in
particular
) or the ZendEngine2 mailing list which is archived at
http://www.zend.com

There is a _LOT_ of code out there using that. Metabase 
among others. Is there an alternative?  This could be a 
huge problem if there is none. 
 
Thanks

This "feature" was undocumented in PHP4 and was never intended to work.

Description:
------------
When trying to reassign $this (from session data for 
example) I get an error: 
Fatal error: Cannot re-assign $this in... 
 
Code used: 
$this = unserialize($data); 
 
This works in php 4. Perhaps this is a feature change but 
I could not find a reference to any alternatives so I am 
submitting a bug just in case. 
 
Thanks!

Reproduce code:
---------------
$this = unserialize($data);

Expected result:
----------------
Assignment of session or serialized data to $this object 

Actual result:
--------------
Fatal error: Cannot re-assign $this in...
