If someone want to get a COM object out of a DCOM object can do something like that:
<?php
$dcom_obj = new COM('dacom.object','remotehost') or die("Unable to get DCOM object!");
$com_obj = new Variant(NULL);
$dcom_obj->Get_Module($com_obj); //user function which returns a custom IDispatch (casted as variant*)
?>
Hopefully this will help someone, because it took me quite long to figure this out.
XV. COM 和 .Net（Windows）函数
简介
COM is an acronym for Component Object Model; it is an object orientated layer (and associated services) on top of DCE RPC (an open standard) and defines a common calling convention that enables code written in any language to call and interoperate with code written in any other language (provided those languages are COM aware). Not only can the code be written in any language, but it need not even be part of the same executable; the code can be loaded from a DLL, be found in another process running on the same machine, or, with DCOM (Distributed COM), be found in another process on a remote machine, all without your code even needing to know where a component resides.
There is a subset of COM known as OLE Automation which comprises a set of COM interfaces that allow loose binding to COM objects, so that they can be introspected and called at run-time without compile-time knowledge of how the object works. The PHP COM extension utilizes the OLE Automation interfaces to allow you to create and call compatible objects from your scripts. Technically speaking, this should really be called the "OLE Automation Extension for PHP", since not all COM objects are OLE compatible.
Now, why would or should you use COM? COM is one of the main ways to glue applications and components together on the Windows platform; using COM you can launch Microsoft Word, fill in a document template and save the result as a Word document and send it to a visitor of your web site. You can also use COM to perform administrative tasks for your network and to configure your IIS; these are just the most common uses; you can do much more with COM.
Starting with PHP 5, this extension (and this documentation) was rewritten from scratch and much of the old confusing and bogus cruft has be removed. Additionally, we support the instantiation and creation of .Net assemblies using the COM interoperability layer provided by Microsoft.
Please read this article for an overview of the changes in this extension in PHP 5.
需求
COM functions are only available for the Windows version of PHP.
.Net support requires PHP 5 and the .Net runtime.
安装
本函数库作为 PHP 内核的一部分，不用安装就能使用。
PHP 的 Windows 版本已经内置该扩展模块的支持。无需加载任何附加扩展库即可使用这些函数。
You are responsible for installing support for the various COM objects that you intend to use (such as MS Word); we don't and can't bundle all of those with PHP.
For Each
Starting with PHP 5, you may use PHP's own the 节 called foreach 在 16 章 statement to iterate over the contents of a standard COM/OLE IEnumVariant. In laymans terms, this means that you can use foreach in places where you would have used For Each in VB/ASP code.
Arrays and Array-style COM properties
Many COM objects expose their properties as arrays, or using array-style access. In PHP 4, you may use PHP array syntax to read/write such a property, but only a single dimension is allowed. If you want to read a multi-dimensional property, you could instead make the property access into a function call, with each parameter representing each dimension of the array access, but there is no way to write to such a property.
PHP 5 introduces the following new features to make your life easier:
Access multi-dimensional arrays, or COM properties that require multiple parameters using PHP array syntax. You can also write or set properties using this technique.
Iterate SafeArrays ("true" arrays) using the the 节 called foreach 在 16 章 control structure. This works because SafeArrays include information about their size. If an array-style property implements IEnumVariant then you can also use foreach for that property too; take a look at the 节 called For Each for more information on this topic.
Exceptions (PHP 5)
This extension will throw instances of the class com_exception whenever there is a potentially fatal error reported by COM. All COM exceptions have a well-defined code property that corresponds to the HRESULT return value from the various COM operations. You may use this code to make programmatic decisions on how to handle the exception.
运行时配置
这些函数的行为受 php.ini 的影响。
表格 1. COM 配置选项
| 名称 | 默认值 | 可修改范围 | 更新记录 |
|---|---|---|---|
| com.allow_dcom | "0" | PHP_INI_SYSTEM | 自 PHP 4.0.5 起可用 |
| com.autoregister_typelib | "0" | PHP_INI_ALL | 在 PHP 4 中是 PHP_INI_SYSTEM。自 PHP 4.1.0 起可用 |
| com.autoregister_verbose | "0" | PHP_INI_ALL | 在 PHP 4 中是 PHP_INI_SYSTEM。自 PHP 4.1.0 起可用 |
| com.autoregister_casesensitive | "1" | PHP_INI_ALL | 在 PHP 4 中是 PHP_INI_SYSTEM。自 PHP 4.1.0 起可用 |
| com.code_page | "" | PHP_INI_ALL | 自 PHP 5.0.0 起可用 |
| com.typelib_file | "" | PHP_INI_SYSTEM | 自 PHP 4.0.5 起可用 |
以下是配置选项的简要解释。
- com.allow_dcom
如果打开此选项，PHP 将被允许以一个 D-COM（Distributed COM）客户方式操作并允许 PHP 脚本在远程服务器上实例化 COM 对象。
- com.autoregister_typelib
When this is turned on, PHP will attempt to register constants from the typelibrary of objects that it instantiates, if those objects implement the interfaces required to obtain that information. The case sensitivity of the constants it registers is controlled by the com.autoregister_casesensitive configuration directive.
- com.autoregister_verbose
When this is turned on, any problems with loading a typelibrary during object instantiation will be reported using the PHP error mechanism. The default is off, which does not emit any indication if there was an error finding or loading the type library.
- com.autoregister_casesensitive
When this is turned on (the default), constants found in auto-loaded type libraries will be registered case sensitively. See com_load_typelib() for more details.
- com.code_page
It controls the default character set code-page to use when passing strings to and from COM objects. If set to an empty string, PHP will assume that you want CP_ACP, which is the default system ANSI code page.
If the text in your scripts is encoded using a different encoding/character set by default, setting this directive will save you from having to pass the code page as a parameter to the COM class constructor. Please note that by using this directive (as with any PHP configuration directive), your PHP script becomes less portable; you should use the COM constructor parameter whenever possible.
注: This configuration directive was introduced with PHP 5.
- com.typelib_file
When set, this should hold the path to a file that contains a list of typelibraries that should be loaded on startup. Each line of the file will be treated as the type library name and loaded as though you had called com_load_typelib(). The constants will be registered persistently, so that the library only needs to be loaded once. If a type library name ends with the string #cis or #case_insensitive, then the constants from that library will be registered case insensitively.

Since my last post, I struggled hard to find a way to pass parameters to Crystal. Luckly, all I needed was to restrict results from a query, so I found this simple solution:
// by dfcp/mar/06
$ObjectFactory= New COM("CrystalReports11.ObjectFactory.1");
$crapp = $ObjectFactory->CreateObject("CrystalDesignRunTime.Application");
$creport = $crapp->OpenReport($my_report, 1);
$creport->FormulaSyntax = 0;
$creport->RecordSelectionFormula = "{cadastro.id}>10 and {cadastro.id}<20";
notice that RecordSelectionFormula must be in Crystal Syntax, and the FormulaSyntax=0 makes it work 100% of the time (I suspect that it's bug, although they1 don't seem to think so).
If you need to pass parameters to, say, multiply some field by, IMHO the right way is to use ParameterFields, but the code above hangs on the last line:
$z = $creport->ParameterFieldDefinitions->Item(1); //gets the first parameter
$z->SetCurrentValue( "teste" ); // hangs here
I saw this at some ASPX foruns... no idea why it doesn't work here on PHP... feedback would be highly appreciated.

I couldn't find much on Crystal Reports and COM's when I went to tackle it
so I thought a few lines of code here may help out anyone looking for where
to get started in the future.
$crapp = new COM("CrystalRuntime.Application.10");
$creport = $crapp->OpenReport($reportToRun, 1);
//reportToRun=full path to *.rpt file
$creport->Database->Tables->
Item(1)->ConnectionProperties['User ID'] = $user;
$creport->Database->Tables->
Item(1)->ConnectionProperties['Password'] = $pass;
//fomatType = integer 22=xls, 31=pdf etc
$creport->ExportOptions->FormatType = $formatType;
//type 1 is to output to a file I think 2 is email
$creport->ExportOptions->DestinationType = 1;
//location = full path to report output file
$creport->ExportOptions->DiskFileName = $location;
$creport->DiscardSavedData();
$creport->Export(False);

There's no way to use static dlls in php. only way to use a dll in php is to make it a com object first and then using it in php like this
<?php
$NewCom=new COM("uni.example");
?>
once we created the COM object this can be used like any other php classes.

If you are using a COM object that opens windows or dialogs (like Office applications), those windows or dialogs will not appear and will stay invisible even if you use codes like
$word->visible = true;
To solve this problem, go to the web service properties (Administrative Tools) and click (in the Logon TAB) "Allow the Service to Iterate with desktop".
This explain lots of problems to close applications. When you try to close, the dialos asking to save the file must appear, but only in the option to iterate with desktop is on.
Hope it helps.

ADO + PHP5 + SQL DATE FIELDS
Using a COM("ADODB.Connection") object in PHP4 and PHP5 to return date fields in databases will have different results.
In PHP4, the date is returned as a string as represented in the database. In my case, '2005-04-11 11:35:44'.
In PHP5, the date is returned as a VARIANT type, when printed or implicitly casted would result as '4/11/2005 11:35:44 AM'.
For this example, the solution is to use the variant conversion function variant_date_to_timestamp() to convert the value to a Unix timestamp.
Please refer to this as an example. Other date types may be converted using one of the other variant_<convert> functions.

After alot of trouble with IIS 6/Windows 2003 and PHP 5.0.2 I figured out how to use Imagemagick COM+/OLE interface. Seems you have to recreate the COM object after each convert() otherwise it will sometimes fail with very strange errors, since the PHP COM interface is not as stable as the old ASP one apparently is.

if you want to add a new hyperlink with excel :
$cell=$sheet->Range('O'.$j);
$cell->Hyperlinks->Add($cell ,'here_your_file');
I write this note because is very difficult to find
the good method to do that .
Merci beaucoup

[Editor's Note:
Serializing the object, storing it and then (on the next page) unserializing it WILL work.
End Note]
the big problem for PHP is it can't save in session an COM object
an samples code is here. This works just first time, then give the error:
Call to undefined method com::Refresh() on line $mMap->Refresh();
the reson is he can't save the object $mMap in session
<?php
session_start();
if (isset($_SESSION['map'])) {
$mMap = $_SESSION['map'];
}
else
{
$ArcIMSConnector = new COM ("aims.ArcIMSConnector") or die("can not create AIMS message object");
echo "Loaded ArcIMSConnector, <br>";
$ArcIMSConnector->ServerName = "map.sdsu.edu";
$ArcIMSConnector->ServerPort = 5300;
$mMap = new COM ("aims.Map") or die("can not create aims.Map message object");
echo "Loaded aims.Map, <br>";
print "AIMS-ServerName= $ArcIMSConnector->ServerName <br>";
$resultInit= $mMap->InitMap($ArcIMSConnector,"Worldgeography");
$mMap->Width = 400; // 'Width of the map in pixels
$mMap->Height = 300; // 'Height of the map in pixels
$mMap->BackColor = 15130848;
$_SESSION['map'] = $mMap;
}
$resultRefresh = $mMap->Refresh(); //Refresh the map
$urlImage = $mMap->GetImageAsUrl();
print "<br>urlImage=$urlImage<br>";
print "<br><IMG SRC='$urlImage'>";
/*
$ArcIMSConnector->Release();
$ArcIMSConnector = null;
$mMap->Release();
$mMap = null;
*/

To pass a parameter by reference to a COM function, you need to pass VARIANT to it. Common data types like integers and strings will not work for it.
As an example, calling a function that retrieves the name of a person will look like:
$Name = new VARIANT;
$comobj = new COM("MyCOMOBj.Component") or die("Couldn't create the COM Component");
if(!$comobj->GetName($Name)) {
echo("Could not retrieve name");
}
else {
echo("The name retrieved is : " . $Name->value);
}
$Name->type will contain the type of the value stored in the VARIANT e.g. VT_BSTR.
Note For PHP 5:
Insted of '$Name->value', we can use only '$Name' for getting the value stored in the VARIANT. To get the type of the value stored in the VARIANT, use 'variant_get_type($Name)'.

For those of us that are not experts with object models, if you have Microsoft Excel or Microsoft Word available, go into the Visual Basic Editor (Alt+F11). Now you can open the object browser window (F2) and see what you find.
If you select "Word" in the object browser, then the classes and members of that class are displayed below. For example, if you click on "Selection" in the classes column, and then "Font" in the members column, you will then see "Property Font As Font Member of Word.Selection" displayed at the bottom. Click on the "Font" link there.
Click on Word "Selection" again in the classes column, and then "PageSetup" in the members column, you will then see "Property PageSetup As PageSetup Member of word.Selection" displayed at the bottom. Click on the "PageSetup" link there.
Using the above examples, you can now formulate your Word Document from php. Here is a simple example that creates a 1 & 1/2" space for text based on the margin settings & with dark red text and an 8pt Helvetica font face:
$content = "Insert Sample Text Here\n\nThis starts a new paragraph line.";
$word= new COM("word.application") or die("Unable to create Word document");
print "Loaded Word, version {$word->Version}\n";
$word->Visible = 0;
$word->Documents->Add();
$word->Selection->PageSetup->LeftMargin = '3"';
$word->Selection->PageSetup->RightMargin = '4"';
$word->Selection->Font->Name = 'Helvetica';
$word->Selection->Font->Size = 8;
$word->Selection->Font->ColorIndex= 13; //wdDarkRed = 13
$word->Selection->TypeText("$content");
$word->Documents[1]->SaveAs("some_tst.doc");
$word->quit();
echo "done";
This example (and others) worked for me with Microsoft Word 10.0 Object Library (MS Word 2002), Apache & PHP on Windows XP. Experimenting using the Visual Basic editor will yield some amazing documents from PHP as it will help you see the relationships of the objects used and give you an idea as to how to construct your code. But be prepared for an occaisional PHP.exe crash if your code is way off base.
Hope this helps!

If you are having issues with the outlook.application locking up when you try to access it, ensure that your apache server is running in the context of a user on the machine instead of the system account.

If you want to use ms indexing server by querying it from ms sql server in a stored procedure with parameters you can do the following:
1.) Create the Catalog named 'myIndexServer' in indexing server
2.) execute addLinkedServer in query analyzer
EXEC sp_addlinkedserver
@server = 'myIndexServer',
@srvproduct = 'Index Server',
@provider = 'MSIDXS',
@datasrc = 'myIndexServer'
GO
in case myIndexServer already exist choose another name or
delete it (be carefull)
EXEC sp_dropserver myIndexServer
GO
3.) Write the following string in query analyzer
declare @sql varchar(1000)
declare @searchFor varchar(400)
set @searchFor = 'phporsomething'
set @sql =' SELECT Path, Filename
FROM OPENQUERY( pmsIndexServer,
''SELECT Path, Filename FROM
pmsProtokollAnhaengeIndex..SCOPE()
WHERE CONTAINS( '''''+@searchFor+''''' )'' ) AS dres' -- end of long sql-string
exec (@sql)
Attention 5 times ' !!!
4.) Execute the string (F5)
5.) Create a simple stored procedure and copy the string from step 3. Make @searchFor an parameter of your sp
6.) You are done, lean back, enjoy and relax

A nice feature you get with COM is the ability to connect to the Windows Management Instrumentation (WMI for short). This allows you to monitor various system statistics (e.g. disk space en cpu usage) of local and remote systems.
Small example:
<?php
$hostname = ".";
$wmi = new COM("WinMgmts:{impersonationLevel=impersonate}
//{$hostname}/root/cimv2");
$cpus = $wmi->ExecQuery("Select * from Win32_Processor");
foreach ($cpus as $cpu)
{
echo trim($cpu->Name)." {$cpu->MaxClockSpeed}MHz {$cpu->LoadPercentage}%\n";
}
?>
will give you this:
Intel Pentium III processor 860MHz 1%
Intel Pentium III processor 860MHz 2%

Useful PHP MSWord class I created to do some simple file conversions. This class could have a lot more to it but I am not familiar with all the COM MS Word function calls.
<?php

Example 1, opens an html file, writes text to it, then saves it as a document:
<?php
$input = "C:\\test.htm";
$output = "C:\\test.doc";
$Word = new MSWord;
$Word->Open($input);
$Word->WriteText("This is a test ");
$Word->SaveAs($output);
$Word->Quit();
?>
Example 2, opens an html file, then saves it as a rtf file:
<?php
$input = "C:\\test.htm";
$output = "C:\\test.rtf";
$Word = new MSWord;
$Word->Open($input);
$Word->SaveAs($output, $wdFormatRTF);
$Word->Quit();

}
function ado_fetch_array( $rs, $result_type, $row_number = -1 )
{
global $ADO_NUM, $ADO_ASSOC, $ADO_BOTH;
if( $row_number > -1 ) // Defined in adoint.h - adBookmarkFirst = 1
$rs->Move( $row_number, 1 );
if( $rs->EOF )
return false;
$ToReturn = array();
for( $x = 0; $x < ado_num_fields($rs); $x++ )
{
if( $result_type == $ADO_NUM || $result_type == $ADO_BOTH )
$ToReturn[ $x ] = $rs->Fields[$x]->Value;
if( $result_type == $ADO_ASSOC || $result_type == $ADO_BOTH )
$ToReturn[ $rs->Fields[$x]->Name ] = $rs->Fields[$x]->Value;

$rs->MoveNext();
return $ToReturn;
