Description:
------------
I've a problem with COM objects.
It's very similar to the bug #33734. In fact, I think that it is the same problem but the bug is supposed to be fixed since 5.1.0. I use the 5.2.5 and have the same problem.

Excuse me for my clumsy english, I hope that my report will be readable.


Reproduce code:
---------------
Here is the code :

<?php
// Creation of the COM object $obj_persist
$obj_persist = new COM("PERSIST.PersistCtrl.1")or die("Error");
$obj_appli = $obj_persist->Applications->Add($path);
$obj_unite = $obj_appli->Units->Add("foo");
$obj_instance = $obj_unite->objects->add($nom_instance);
$sous_objet = $obj_instance->collection("Objects");
$propriete = $sous_objet->Item("alm");
echo "Label Value : " . $propriete->Value("Label",0); //Returns the good Value

// Test 1
$propriete->Value("Label",0) = "New Label";
// Fatal Error


//Test 2
$propriete->Value["Label",0] = "New Label";
// Invalid number of parameters.




Expected result:
----------------
I've tried many ways of writing the $propriete->Value["Label",0]. With (), [], mix of both. I cannot write on the value.
I though it was a read-only value but when I tried with VBa, it worked perfectly. Here is the code.

Dim SsObjs as PrsCollObjects
Set SsObjs = MyInst.Collection("Objects")
Set MyObject = SsObjs.Item("Fault")
MyObject.Value("Label", 0) = "D?faut pompe 1"

Actual result:
--------------
Result of TEST 1 with () :

Fatal error: Can't use method return value in write context in C:\wamp\www\Test COM\index.php on line 71



Result of TEST 2 with [] :

Fatal error: Uncaught exception 'com_exception' with message 'Error [0x8002000e] Nombre de param?tres non valide. ' in C:\wamp\www\Test COM\index.php:69 Stack trace: #0 C:\wamp\www\Test COM\index.php(69): unknown() #1 {main} thrown in C:\wamp\www\Test COM\index.php on line 69

Depending on the way I write with [], I also have an "Unexpected ','" error.

I have the same problem (Fatal error: Can't use method return value in write context in ...), with PHP 5.2.6 , Apache 2.2.9 , and Windows 2003 Server.

I'm not able to do this:
$obj->Attribute('data1') = "test";

This is also not working like this:
$obj->Attribute['data1'] = "test";

and it's working in VBS so I know it should work here also.

Is there a way I can help in order to make this bug evolve ?
I can provide any requested logs and can perform tests to help to solve this problem because I really need this feature.
I'm not really keen on using an ASP page to make this single function.

Regards.

This should likely have been

  $propriete->Value["Label"][0] = "New Label";

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.
