Peachpie - Open Source PHP Compiler to .NET and WordPress under ASP.NET Core

The Peachpie PHP compiler project joined the .NET Foundation this week and I'm trying to get my head around it. PHP in .NET? PHP on .NET? Under .NET? What compiles to what? Why would I want this? How does it work? Does it feel awesome or does it feel gross?

Just drink this in.

C:\Users\scott\Desktop\peachcon> type program.php
<?php

function main()
{
echo "Hello .NET World!";
}

main();

C:\Users\scott\Desktop\peachcon> dotnet run
Hello .NET World!

Just like that. Starting from a .NET SDK (They say 1.1, although I used a 2.0 preview) you just add their templates

dotnet new -i Peachpie.Templates::*

Then dotnet new now shows a bunch of php options.

C:\Users\scott\Desktop\peachcon> dotnet new | find /i "php"
Peachpie console application peachpie-console PHP Console
Peachpie Class library peachpie-classlibrary PHP Library
Peachpie web application peachpie-web PHP Web/Empty

dotnet new peachpie-console for example, then dotnet restore and dotnet run. Boom.

NOTE: I did have to comment out his one line "<Import Project="$(CSharpDesignTimeTargetsPath)" />" in their project file that doesn't work at the command line. It's some hack they did to make things work in Visual Studio but I'm using VS Code. I'm sure it's an alpha-point-in-time thing.

It's really compiling PHP into .NET Intermediate Language!

PHP to .NET

You can see my string here:

Hello .NET World inside a PHP app inside the CLR

But...why? Here's what they say, and much of it makes sense to me.

  1. Performance: compiled code is fast and also optimized by the .NET Just-in-Time Compiler for your actual system. Additionally, the .NET performance profiler may be used to resolve bottlenecks.
  2. C# Extensibility: plugin functionality can be implemented in a separate C# project and/or PHP plugins may use .NET libraries.
  3. Sourceless distribution: after the compilation, most of the source files are not needed.
  4. Power of .NET: Peachpie allows the compiled WordPress clone to run in a .NET JIT'ted, secure and manageable environment, updated through windows update.
  5. No need to install PHP: Peachpie is a modern compiler platform and runtime distributed as a dependency to your .NET project. It is downloaded automatically on demand as a NuGet package or it can be even deployed standalone together with the compiled application as its library dependency.

PHP does have other VMs/Runtimes that are used (beyond just PHP.exe) but the idea that I could reuse code between PHP and C# is attractive, not to mention the "PHP as dependency" part. Imagine if I have an existing .NET shop or project and now I want to integrate something like WordPress?

PHP under ASP.NET Core

Their Web Sample is even MORE interesting, as they've implemented PHP as ASP.NET Middleware. Check this out. See where they pass in the PHP app as an assembly they compiled?

using Peachpie.Web;

namespace peachweb.Server
{
class Program
{
static void Main(string[] args)
{
var host = new WebHostBuilder()
.UseKestrel()
.UseUrls("http://*:5004/")
.UseStartup<Startup>()
.Build();

host.Run();
}
}

class Startup
{
public void ConfigureServices(IServiceCollection services)
{
// Adds a default in-memory implementation of IDistributedCache.
services.AddDistributedMemoryCache();

services.AddSession(options =>
{
options.IdleTimeout = TimeSpan.FromMinutes(30);
options.CookieHttpOnly = true;
});
}

public void Configure(IApplicationBuilder app)
{
app.UseSession();

app.UsePhp(new PhpRequestOptions(scriptAssemblyName: "peachweb"));
app.UseDefaultFiles();
app.UseStaticFiles();
}
}
}

Interesting, but it's still Hello World. Let's run WordPress under PeachPie (and hence, under .NET). I'll run MySQL in a local Docker container for simplicity:

docker run -e MYSQL_ROOT_PASSWORD=password -e MYSQL_DATABASE=wordpress -p 3306:3306 -d mysql

I downloaded WordPress from here (note they have the "app" bootstrapper" that hosts .NET and then runs WordPress) restore and run.

WordPress under .NET Core

It's early and it's alpha - so set your expectations appropriately - but it's surprisingly useful and appears to be under active development.

What do you think?

Be sure to explore their resources at http://www.peachpie.io/resources and watch their video of WordPress running on .NET. It's all Open Source, in the .NET Foundation, and the code is up at https://github.com/iolevel/ and you can get started here: http://www.peachpie.io/getstarted

.NET 4.1 Preview - New Base Class Library (BCL) Extension Methods - RFC

April 1, '09 Comments [16] Posted in ASP.NET | DLR | Javascript | Learning .NET | Microsoft | Musings | Open Source | PHP | Programming | Python | Silverlight | Source Code | Tools | VB | Web Services | Windows Client | XML

As web programmers, we use a lot of strings to move data around the web. Often we’ll use a string to represent a date or an integer or a boolean. Basically "1" in instead of 1, or "April 1, 2009" rather than a proper ISO-8601 formatted culture-invariant date.

While these strings are flying around via HTTP it's not a huge deal, but sometimes this loose, even sloppy, use of strings can leak into our own code. We might find ourselves leaving the data times as strings longer and longer, or not even bothering to convert them to their proper type at all. This problem is made worse by the proliferation of JSON, and schema-less/namespace-less XML (that I've often called "angle-bracket delimited files" as they're no more useful than CSVs in that point.

.NET 4.0 is pretty much locked down, but version 4.1 still has some really cool "Futures" features that are being argued about. If we don't know the type of a string, or we want to leave the string, as a string, longer than usual, what if we had an class that could be both a string and another type, essentially deferring the decision until the variable is observed. For example:

StringOr<int> userInput= GetUserInput("Quantity"); 
string szUserInput=userInput.StringValue; 
int intUserInput=userInput.OtherValue;

Sometimes you just don't know, or can't know.

This reminds me of a similar, but orthogonal physics concept, that of the Heisenberg Uncertainty Principle. Sometimes you know that an object is a string, and sometimes you know how long it is, but you can’t know both at the same time.

One of my favorite jokes goes:

Heisenberg gets pulled over by the police. The officer asks, “Do you know how fast you were going?” Heisenberg answers, “No, but I know exactly where I am!”

This library doesn't solve THAT issue, with respect to strings, but we’ve got folks in DevDiv working on this and many other metaphysical - and physical - problems as they apply to computer science.

Big thanks to Eilon, who's working hard to get this pushed into the .NET 4.1 Base Class Library. Visit Eilon's blog for more details on this new library, more code, graphics and details on how Intellisense will handle this new case.

Hopefully, someone is working to make this important new library Open Source.

Your thoughts, Dear Reader?

The Weekly Source Code 20 - A Web Framework for Every Language

March 19, '08 Comments [15] Posted in Javascript | PHP | Programming | Ruby | Source Code

vt102

We just keep oscillating back and forth between thin clients and chubby clients. We started with basic terminals receiving text from the server and displaying it, then added control codes and more smarts until we got into things like VT102 and beyond. We pushed all the User Interface over to the client for rendering.

Now that the Web is squarely here to stay, we've got islands of activeness in the form of browser plugins like Flash and Silverlight, some of which are cross platform and some less-so, but for now my quad-processor machine spends a lot of time either:

  • Waiting for markup to show up
  • Rendering markup

There's a thousand different ways to generate your UIs and send them down to the browser/client for rendering. Turns out there are as many ways as there are languages. If you've got a programming language, there's a web framework for it.

I don't know why this surprises me. Folks love their programming language, whatever it is, and it makes sense that the "ultimate" proof of their language's awesomeness would be the "ultimate web framework."

That said, it still seems funny to me that the greatest (er, most overtly visible) example of a language's superiority is how well it works as a Web Framework angle-bracket generator.

For example, Arc is Paul Graham's new LISP dialect that a number of people are talking about (with varying degrees of enthusiasm).  A tutorial on Arc is available here and there's an "Arc Challenge" being discussed here as folks try to this slightly more complex Hello World example:

"First generate a page with an input field and a submit button. If the user clicks on submit, he gets a second page with a link saying "click here." If he clicks on that, he gets a third page saying "you said: ..." where ... was whatever he put in the input field. This has to happen without the value being passed in the url; it should not be possible to change the behavior of the third page by editing the url in the second."

In Arc/LISP it looks like this:

  (defop said req
    (aform [w/link (pr "you said: " (arg _ "foo"))
             (pr "click here")]
      (input "foo")
      (submit)))

It's pretty terse to look at if you're used to doing things in more conventional languages. There's a lot of fun solutions like this entirely client-side one in JQuery:

$('body').append('<input id = "myInput" /><input type = "submit" />')
    .find('input[@type=submit]').click(function() {
       val = $('#myInput').val();
       $('body').html('<a href = '#'>click here</a>').find('a').click(function() {
          $('body').html('You said: ' + val);
       });
    });

Other examples include:

#!/usr/bin/env ruby
  require "ramaze"
  class MainController < Ramaze::Controller
    def index
      if f = session['foo'] then "you said #{f}"
      elsif session['foo'] = request['foo'] then A("click Here", :href => '/')
      else '<form><input name="foo" /><input type="submit"></form>'
      end
    end
  end
  Ramaze.start :port => 7001
  __END__ 

Then Rails:

def said
    if request.method == :post
      session[:said] = params[:said]
      render :action => "clickhere"
    else
      render :action => "result" if session[:said]
    end
  end

  default template said.rhtml:
  <% form_tag do %><%= text_field_tag "said", "" %><%= submit_tag %><% end %>

  clickhere.rhtml:
  <%= link_to "click here", "" %>
  
  result.rhtml:
  You said <%= session[:said] %>
| something |	
something := self request: 'Say something'.	
self inform: 'Click here'.	
self inform: something
serveAs "said" $ hasIndex $ \x -> "click me" `linksTo` (text ("You said " ++ x))
<%@ Page Language="C#" ClassName="WebApplication1._Default" %>
  <script runat="server">
    // C# and ASP.NET
    protected void SubmitButton_Click(object sender, EventArgs e)
    {
        MultiView1.ActiveViewIndex = 1;
    }
    protected void ClickHereButton_Click(object sender, EventArgs e)
    {
        SaidLabel.Text = string.Concat("You said: ", SayTextBox.Text);
        MultiView1.ActiveViewIndex = 2;
    }
  </script>

  <html>
  <head runat="server">
    <title></title>
  </head>
  <body>
    <form id="form1" runat="server">
      <asp:MultiView ID="MultiView1" runat="server" ActiveViewIndex="0">
        <asp:View runat="server">
          <asp:TextBox ID="SayTextBox" runat="server" />
          <asp:Button ID="SubmitButton" runat="server" Text="Submit" OnClick="SubmitButton_Click" />
        </asp:View>
        <asp:View runat="server">
          <asp:LinkButton ID="ClickHereButton" runat="server" Text="Click Here" OnClick="ClickHereButton_Click" />
        </asp:View>
        <asp:View runat="server">
          <asp:Label ID="SaidLabel" runat="server" />
        </asp:View>
      </asp:MultiView>
    </form>
  </body>
  </html>

Shorter but not-typical ASP.NET:

Shorter but non-idiomatic C#/ASP.NET:

    <%@ Page Language="C#" %>
    <html>
    <head>
    <title>Said</title>
    </head>
    <body>
        <form id="form" runat="server">
            <% if (!IsPostBack) { %>
                <input name="foo" />
                <input type="submit" />
            <% } else if (Request.Form["foo"] != null) {
                Session["foo"] = Request.Form["foo"]; %>
                <a href="javascript:form.submit()">click here</a>
            <% } else { %>
                you said: <%=Session["foo"]%>
            <% } %>
        </form>
     </body>
    </html>

There are so many ways to generate the same result. Big thanks to Ted Glaza for his indirect help on this post.

HTTP Error 404.17 - PHP on IIS7 under 64bit Vista

October 17, '07 Comments [5] Posted in IIS | Vista | PHP
Sponsored By

IIS 7.0 Detailed Error - 404.17 - Not Found - Windows Internet Explorer If you're getting...

"HTTP Error 404.17 - Not Found - The requested content appears to be script and will not be served by the static file handler."

...on Vista while trying to get PHP working under IIS7 with the standard ISAPI "php5isapi.dll" ask yourself, are you running 64-bit? That ISAPI DLL is a 32-bit DLL, so you'll have to either change your default Application Pool to enable 32-bit, or preferably create a separate 32-bit AppPool for your PHP Application.

Right click on the Application Pool and select "Advanced Settings" then "Enable 32-bit Applications."

Advanced Settings

At this point, you're all set with the standard ISAPI PHP stuff. 

phpinfo() - Windows Internet Explorer

Even better, consider using the FastCGI for IIS component. I'll do a screencast on that soon.
