New Comment:
in this case you should be doing:
try {
$a = new COM(...);
// use it here
} catch (exception $e) {
// failed to create it
}
in other cases, where you have been passed the object, use is_object()
to check if it is valid.
I'll see if I can fix the shorthand "if (!$a)" syntax someone in the
next month.

Some objects work and some not. The following code creates an object
that works not. It throws a COM exception "Member not found". Test it
for yourself, I hope it will fail :-)
---------------------------------
$o = new COM("WScript.Shell");
if (!$o)
/* dummy */ ;
else
echo $o->CurrentDirectory;

What is the full error message?

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?
