PHP COM('word.application') 函数和方法参数问题

Question

I'm using php and new COM('word.application') to manipulate a .doc file (add and edit fields), I'm on a Windows Server 2012 R2 with apache 2.4.25 x64 and php 7.0.17 x64.

So far I made a simple code which work great, but I have an issue when using functions with multiple parameters like this one

$word->Documents[1]->Protect(3, false, 'mypassword', false, false);

I get the following error :

[Erreur] Impossible de lancer le connecteur Microsoft Office Word. : com_exception: Parameter 4: Le type ne correspond pas

Approx translation in english :

[Error] Impossible to laungh the Microsoft Office Word connector : com_exception: Parameter 4: type does not correspond

In VBA code like this it's working

ActiveDocument.Protect Type:=wdAllowOnlyFormFields, NoReset:=True

According to the doc found in VBA

t.com/en-us/library/office/aa220366(v=office.11).aspx

Parameters 2, 4 and 5 should be booleans, so I don't know why I'm getting this error. If i remove parameters 4 and 5, I get the same error but on parameter 2.

With some searches i looked at the object new VARIANT() but it didn't work too.

I have also the problem with $this->Documents 1 ->SaveAs()

$fileName = "D:\\test.doc";
$this->Documents[1]->SaveAs($fileName);

It works.

According to the doc ( https://msdn.microsoft.com/en-us/library/microsoft.office.tools.word.document.saveas(v=vs.120).aspx ) I should be able to use a second parameter like this :

$fileName = "D:\\test.doc";
$fileFormat = 0;
$this->Documents[1]->SaveAs($fileName, $fileFormat);

Like this I have the error "Parameter 0: Le type ne correspond pas" (Type does not correspond).

In VBA it's working differently, maybe I'm doing something wrong ...

Much thanks if you help me :)

edit : full example code

<?php

$word = new COM("word.application") or die("Cannot create Word object");
echo "com object created<br>";
$word->Visible = false;
$word->WindowState = 2;
$word->DisplayAlerts = false;
$word->Documents->Open("D:\\test.doc");
echo "document loaded<br>";

$import = $word->Documents[1]->VBProject->VBComponents->Import("D:\\fr.mac");
$import->name = "Macrofr";

$myModule = $word->Documents[1]->VBProject->VBComponents->Import("D:\\test1.mac");
$myModule->name = "MacroInit";

$myModule2 = $word->Documents[1]->VBProject->VBComponents->Import("D:\\test2.mac");
$myModule2->name = "MacroFonction";

$myModule3 = $word->Documents[1]->VBProject->VBComponents->Import("D:\\test3.frm");
$myModule3->name = "MacroProgression";


$word->Documents[1]->Protect(3,false,'motdepasse',false,false); // (type de protection,noReset,mdp)

$word->Documents[1]->SaveAs("D:\\doc_with_macro.doc", 0);
$word->Documents[1]->Close();
echo "closing doc<br>";

$word->Quit();
$word = null;
echo "end<br>";

The only problem that I see in this code is related to protect function . First parameter must be VARIANT like this :

$word->Documents[1]->Protect(
        new VARIANT(3, VT_I4),
        false,
        'Your password',
        false,
        true
  );
