If you are frustrated that print_r($obj) (where $obj is something returned from a call to a function on a COM object) does not return anything helpful, and that variant_get_type($obj) just returns a number, the function you are actually after is:
com_print_typeinfo($obj);
It lists all functions, variables, their types in a human-readable (well, programmer-readable) format. Lovely!
VARIANT
(No version information available, might be only in CVS)
VARIANT — VARIANT trieda
$vVar = new VARIANT($var)
Popis
Jednoduchý kontainer na zabalenie premenných do VARIANT štruktúr.
Metódy
string VARIANT::VARIANT
([ mixed $value
[, int $type
[, int $codepage
]]] )
Konštruktor VARIANT triedy. Parametre:
- value
- počitatočná hodnota. Ak sa vynehá, vytvorí sa objekt VT_EMPTY.
- type
- určuje typ obsahu objektu VARIANT. Možné hodnoty sú VT_UI1, VT_UI2, VT_UI4, VT_I1, VT_I2, VT_I4, VT_R4, VT_R8, VT_INT, VT_UINT, VT_BOOL, VT_ERROR, VT_CY, VT_DATE, VT_BSTR, VT_DECIMAL, VT_UNKNOWN, VT_DISPATCH and VT_VARIANT. Tieto hodnoty sa navzájom vylučujú, ale dajú sa skombinovať s VT_BYREF na určenie hodnoty. Ak sa vynehá, použije sa typ value . Pozrite si msdn knižnicu pre dodatočné informácie.
- codepage
- určuje kódovú stránku, ktorá sa používa na konvertovanie php-reťazcov na unicode-reťazce a naopak. Možné hodnoty sú CP_ACP, CP_MACCP, CP_OEMCP, CP_SYMBOL, CP_THREAD_ACP, CP_UTF7 a CP_UTF8.

Running PHP 4.3.2 on Windows 2000 I had to use the following expression to create an empty Variant:
<?php
$empty = new Variant(null);
print $empty->type // ==> 1
?>
NOT
<?php
$empty = new Variant();
print $empty->type // ==> 0
?>
The two expressions return different Variant type values!

With thanks to Harald Radi and Wez Furlong.
Some VBA functions have optional parameters. Sometimes the parameters you want to pass are not consecutive.
e.g.
GoTo What:=wdGoToBookmark, Name="BookMarkName"
GoTo(wdGoToBookmark,,,"BookMarkName)
In PHP, the "blank" parameters need to be empty.
Which is ...
<?php
// Some servers may have an auto timeout, so take as long as you want.
set_time_limit(0);
// Show all errors, warnings and notices whilst developing.
error_reporting(E_ALL);
// Used as a placeholder in certain COM functions where no parameter is required.
$empty = new VARIANT();
// Load the appropriate type library.
com_load_typelib('Word.Application');
// Create an object to use.
$word = new COM('word.application') or die('Unable to load Word');
print "Loaded Word, version {$word->Version}\n";
// Open a new document with bookmarks of YourName and YourAge.
$word->Documents->Open('C:/Unfilled.DOC');
// Fill in the information from the form.
$word->Selection->GoTo(wdGoToBookmark,$empty,$empty,'YourName'); // Note use of wdGoToBookmark, from the typelibrary and the use of $empty.
$word->Selection->TypeText($_GET['YourName']);
$word->Selection->GoTo(wdGoToBookmark,$empty,$empty,'YourAge');
$word->Selection->TypeText($_GET['YourAge']);
// Save it, close word and finish.
$word->Documents[1]->SaveAs("C:/{$_GET['YourName']}.doc");
$word->Quit();
$word->Release();
$word = null;
print "Word closed.\n";
?>
The example document is ...
Hello [Bookmark of YourName], you are [Bookmark of YourAge] years old.
and it would be called ...
word.php?YourName=Richard%20Quadling&YourAge=35
Regards,
Richard.

<?php
# I think that we need some examples of this thing:
# Lets define a real variant:
$varREAL= new Variant("9.34 is a real number",VT_R8);
print "Value:". $varREAL->value; # Will print 9.34
# Now an integer
$varINT= new Variant("9.34 Printed as an integer",VT_INT);
print "Value:". $varINT->value; # Will print 9
# Now a string
$varSTR= new Variant("9.34 Printed as a string",VT_BSTR);
print "Value:". $varSTR->value; # Will 9.34 Printed as a string
?>
