How to create C# DLL to use in PHP

I’m using a C#.NET DLL with ASP.NET 2.0 and it’s working now. I want to use the same DLL in PHP.

I’m a newbie in PHP; would someone please tell me how to use it in PHP or could you share some example?

Method 1

PHP has a built-in Windows-only extension called DOTNET that allows you to use .NET libraries in a PHP application.

Note that you’ll need to make sure your assemblies are declared as COM visible:

[assembly: ComVisible(true)]

Here are two examples.

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

Another example demonstrating functionality of DOTNET class:

<?php

$full_assembly_string = 'System.Windows.Forms, Version=2.0.0.0, Culture=neutral, PublicKeyToken=a8425bc35256e463';
$full_class_name = 'System.Windows.Forms.Form';
$form = new DOTNET($full_assembly_string, $full_class_name);

// code to add buttons, menus, text, etc

$form->Show();

$form_event = '';
while($form_event !== 'close') {

  // handle form functions and events

  }
?>

Method 2

you are using the PHP Version 5.4.7 you should already have com_dotnet.dll
if you dont have it you can download it on “download” and add to your ext/ path inside php directory.

Edit you php.ini file

extension=php_com_dotnet.dll

Method 3

What you really need is this:

Enable COM-Visibility (I was wrong before)
Sign your assembly (give it a “stong name”, use “sn.exe” to create public-private-keys)
Add your assembly to GAC (use “gacutil.exe”)
When you change your assembly, before adding it to GAC again, make sure your AssemblyVersion (not FileVersion) changes/goes up (you can go down as well)

(you find those tools most probably in “C:Program Files (x86)Microsoft SDKsWindows …”, just google for their correct use, easy enough)

That should do it.
In PHP (example):

<?php
    // use this kind of name, not path to dll or whatever
    // print your assemblly's full name in .NET and use that
    $name = "YourAssembly, Version=1.1.1.1, Culture=neutral, PublicKeyToken=fe6263478ac";
    $obj = new DOTNET($name, "YourNamespace.YourClass");
    echo "successn";
?>

Oh yeah, vaibhav is right about “php.ini”. I didn’t have to edit it. It had the correct values (defaults maybe?).
