PHP Bug Type: COM related
Bug description: Comparing COM object variable with NULL throws an exception
Description:
------------
Comparing COM object variable with NULL throws an exception
Reproduce code:
---------------
$a = new COM(.....);
if (!$a)
{
......
}
else
{
.....
}
Expected result:
----------------
If $a is non null, I expect the ELSE block to be performed.
Actual result:
--------------
PHP throws an exception when trying to evaluate !$a. I think it tries to
access the default COM object's property.
If this is a valid behavior, how should I test for null?
