PHP Fatal error:  instanceof expects an object instance, constant given in Command line code on line 1

Please try using this CVS snapshot:

  http://snaps.php.net/php5.2-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php5.2-win32-latest.zip

The instance of operator was never intended to work with literals, the 
"parameter" must always be a variable.

it may never have been intended to work, however the error really should be a little ...ermm.. better...

I can't be bothered to download and compile a CVS snapshot, so if someone else wants to test feel free, else close the bug, I'm not really that bothered about this oddity :)

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

Thank you for the report, and for helping us make PHP better.
