DOTNET

(PHP 4 >= 4.1.0, PHP 5)

DOTNETDOTNET class

$obj = new DOTNET("assembly", "classname")

Description

The DOTNET class allows you to instantiate a class from a .Net assembly and call its methods and access its properties.

Methods

string DOTNET::DOTNET ( string $assembly_name , string $class_name [, int $codepage ] )

DOTNET class constructor. assembly_name specifies which assembly should be loaded, and class_name specifices which class in that assembly to instantiate. You may optionally specify a codepage to use for unicode string transformations; see the COM class for more details on code pages.

The returned object is an overloaded object, which means that PHP does not see any fixed methods as it does with regular classes; instead, any property or method accesses are passed through to COM and from there to DOTNET. In other words, the .Net object is mapped through the COM interoperability layer provided by the .Net runtime.

Once you have created a DOTNET object, PHP treats it identically to any other COM object; all the same rules apply.

Example #1 DOTNET example

<?php
 $stack 
= new DOTNET("mscorlib""System.Collections.Stack");
 
$stack->Push(".Net");
 
$stack->Push("Hello ");
 echo 
$stack->Pop() . $stack->Pop();
?>

Note: You need to install the .Net runtime on your web server to take advantage of this feature.

First, I hit the same mine:

"... Failed to instantiate .Net object [Unwrapped, QI for IDispatch] [0x80004002] No such interface supported ..."

In order to load the assembly and class in it successfully, I had to change my AssemblyInfo.cs file regarding the visibility of the types in it.

// some code above

// This sets the default COM visibility of types in the assembly to invisible.
// If you need to expose a type to COM, use [ComVisible(true)] on that type.
[assembly: ComVisible(true)]

// some code below

For strongly-named NET assemblies that are registered in the GAC, you can just use the assembly name
e.g: $x = new DOTNET ("myAssembly", "myClass");

For strongly-named NET assemblies that aren't registered in the GAC, you need to use the full assembly string
e.g. $x = new DOTNET('myAssembly, Version=X.X.X.X, Culture=neutral, PublicKeyToken=ZZZZZZZZZZZZ', 'myClass');

You can't instantiate assemblies that haven't been strongly named.

"Strongly named" means that the assembly has a public key. To strongly name your own classes in Visual Studio, go to the Signing tab in the project properties and click the 'sign the assembly' box and choose a key file name.

To register an assembly in the GAC, there are various tools around to do that, but the easiest method is to drag-and-drop the compiled assembly into c:\windows\assembly using windows explorer (a shell extension is installed by default that handles registering dragged files).

In order to find out what the PublicKeyToken value is, open up Explorer and go to c:\windows\assembly.  In that directory you will see all of the registered assemblies along with their PublicKeyToken value.

My HTTPD crashed everytime I used this feature. To fix it, I had to switch to CGI and now everything works fine.

Here is a simple example using .NET Framework in PHP

<?php
$console
= new DOTNET("mscorlib", "System.Console");
$varible = $console->ReadLine();
$console->WriteLine( "Varible: " . $varible );
$console->WriteLine();

unset(
$varible );
unset(
$console );
exit();
?>

If you want to load any other assembly apart from mscorlib, you'll need to include it like the following

$x = new DOTNET('The.Assembly.Name, Version=X.X.X.X, Culture=neutral, PublicKeyToken=ZZZZZZZZZZZZ', 'The.Class.Name');

Replace all relevant details.
