PHP on Windows IRC Channel

Community IRC channel on Freenode: #php-dev-win

Sam Ramji

“Openness produces better outcomes.”

Steve Ballmer said a few weeks ago that WebKit looks interesting.

“It’s critical to embrace competition.”

You can look at competition in two ways: You can look at it in a game like boxing, where if you win, you get the prize, and if you lose you just get beat up. Or you can look at it like a game like chess, where if you win, you get the prize, but if you lose, you got better. Competition drives innovation.

Interoperability in technology: POI (poorly obfuscated implementation), an Apache project. To help this project, Microsoft put the Office binary formats under the Microsoft OSP. Another Apache project that Microsoft is helping is Hadoop by having two Microsoft developers dedicated to working on the project.

Microsoft Web Platform (Lauren Cooney)

Key Foundational Pillars

  • Simplicity
    • Making the Web Stack easily available through one simple download and install process
    • Reducing costs for acquiring the stack (hosters)
  • Interoperability
  • Integration

Vision: the Microsoft Web Platform

  • Provide a better, simpler, more integrated Web Platform to the Web community
  • Simplify adoption of Microsoft’s web platform
  • Create an identity around the core Microsoft Web stack
  • Launch a web stack portal (http://www.microsoft.com/web)

Today’s Microsoft Web Platform

  • Our vision: Freedom for developers to develop with what they want, using the tools they need to be successful
  • Slide shows a graphic detailing the stack
  • Components of the platform must:
    • Be compatible with Top 10 Web applications, regardless of language barriers
    • Allow for automated installation and configuration of Top 10 Web apps
    • Must support shared hosting scenarios, not just dedicated and self-hosting
  • unable to capture all data on the slide

Other slides showing the beta Web Platform installer. PHP is not in there yet, but will be coming in the near future. They are determining what PHP extensions to bundle and what configuration options to provide end-users. They want to hear from the community about the right way to go about bundling PHP in the installer.

  • Provide a single destination on the Web for the best Web applications for Windows (PHP + ASP.NET)
  • Work with the community to enable a streamlined install experience of community apps on Windows
  • Provide an Atom feed of Web apps for partners
  • Use Application Gallery as a channel to drive customers to preferred Windows hosters
  • Integrate into future VS, Windows, & IIS releases
  • Launch timeline: mid 2009

In answer to a question I asked about making IIS understand Apache config directives and .htaccess files, it sounds like the IIS team is actually working on supporting a subset of the Apache config format and reading in the .htaccess files, etc.

Slides will be posted to SlideShare on put on Lauren’s blog at http://cooney.typepad.com/.

What’s New in IIS For PHP Developers (Ruslan Yakushev)

IIS 7.0 Key Highlights

  • Modular and Extensible
  • Integrated Pipeline
  • Delegated Management
  • Diagnostic Capabilities
  • Improved Security

He’s showing the Microsoft Web Application Installer and demo’ing it by using it to install and configure Drupal.

Now showing a demo of the IIS URL Rewrite Module.

It’s not the same as Apache’s mod_rewrite, but it solves the same problem. It allows you to import the application’s .htaccess file, parsing from it the mod_rewrite rules and translating them into IIS format for rewriting URLs.

Summary

  • Reliable and fast hosting of PHP via FastCGI
  • PHP apps can rely on URL rewrite to enable all URL scenarios
  • Use Web Deployment tool to package PHP applications for IIS
  • Scale out and reverse proxy with ARR
  • Use IIS Tracing to debug PHP apps

Windows Azure (Manuvir Das)

What Is the Cloud?

  • A set of connected servers
  • On which developers can:
    • Install and run services
    • Store and retrieve data

When we build cloud services today, it’s akin to building an application from the very ground up. That is, it’s like having to first build a computer and an operating system before you can even start building your application. This is how we build cloud services today, and this is the problem that Microsoft Azure solves.

The answer to this on the desktop is that we have operating systems that handle all of the logic of the system so that we don’t have to build this. Instead, we are free to build our application on top of that. Can we have the same thing in the cloud?

Windows Azure is an operating system for the cloud.

What Does Windows Azure Provide?

  • The same facilities that a desktop OS provides, but on a set of connected servers:
    • Abstract execution environment
    • Shared file system
    • Resource allocation
    • Programming environments
  • And more: Support for utility computing
    • 24/7 operation
    • Pay for what you use
    • Simpler, transparent administration

How Does This Map To Features?

  1. Automated Service Management
    • You define the rules and provide your code
    • The platform follows the rules: deploys, monitors, and manages your service
  2. A powerful service hosting environment
    • All of the hardware: servers, load balancers, etc.
    • Virtualized and direct execution
    • The virtualization is completely transparent
  3. Scalable, available cloud storage
    • Blobs, tables, queues, etc.
  4. A rich, familiar developer experience

Automated Service Management

Develop & Model » Deploy & Run » Maintain Service Health

  • What’s in the model?
    • Service topology and size
    • Health constraints
    • Configuration settings
  • The goal: Keep a service responsive & healthy in the face of failures & upgrades
  • How?
    • Detect failures, violations of health constraints
    • Replace failed/missing resources transparently
  • Made possible by abstraction
    • Service declares logical resources in the model
    • APIs map logical resources to physical entities
    • Service code calls these APIS

In the Azure model, you don’t get to create disk images like in Amazon’s services. Instead, you give Azure your code, and it does everything for you. It is fully managed.

Scalable, Available Cloud Storage

  • Simple, essential storage abstractions:
    • Large items of user data: blobs, file streams1, etc.
    • Service state: simple tables, caches1, etc.
    • Service communication: queues, locks1, etc.
  • With an emphasis on:
    • Massive scale, availability, and durability
    • Geo-distribution and geo-replication1
  • This is not a database service in the cloud (simple tables with a primary key and a partition key that are set up for partitioning across many different servers; you cannot do joins or normalized, relational tables; if you are looking to de-normalize your data, then this is the system for you)

ASP.NET: Architecting for the Cloud

Showing a diagram of an ASP.NET application and how you replace certain parts of the application (like file I/O) with things like blog storage from the cloud, etc.

Rich, Familiar Developer Experience

  • A simulated cloud environment on the desktop (full simulation of the cloud you can install on your desktop)
  • Support for a variety of programming languages
    • ASP.NET, .NET languages, native code1, PHP1
  • An ecosystem of tools and support
    • Integration with Visual Studio, Eclipse1
    • Logging, alerts, tracing1, etc.
    • Samples, documentation, MSDN, forums, etc.

Putting It All Together

Showing diagram of an architecture for how an application works in the cloud.

Demo: Thumbnail Generator

Showing a demo of a thumbnail generator using the simulation environment on the desktop.

CTP – Available Now

  • Open release of the desktop SDK
  • Limited preview of the cloud infrastructure
    • Free usage, with quotas
  • Key features:
    • VMs with dedicated resources
    • ASP.net websites, managed code workers
    • Storage: blobs, tables, queues
    • Single, large datacenter on US west coast
  • Visit http://www.azure.com/windowsazure

Programming Live Services Using Non-Microsoft Technologies (Nishant Gupta)

Why?

  • “Live Services is about synchronizing life” – that is, synchronizing your entire digital life… e-mail, photos, blog entries, music, videos, work documents, your Facebook profile, your MySpace page, etc. This data lives on isolated silos of information.
    • The data
    • The devices the data lives on
    • The applications that render the data
    • The relationships in your digital life (family and friends on Facebook, etc.)

What Can You Do with Live Services?

  • Access user data
  • Share user’s data
  • Sync user’s data
  • Provide news on actions
  • Provide access control to user’s data
  • Manage applications
  • Access user’s profile
  • Access user’s social graph

How Can You Do It?

  • Live Framework - it is the uniform way for programming Live Services from any platform, programming language, application, or device
    • Open - HTTP, XML, Atom, RSS, etc.
    • Simple - sync, clien/cloude symmetry
    • Comprehensive - unified resource model

Resource Model

Showing diagram of the resource model

Live Framework

  • Entry - resource
  • Collection - collection of resources
  • Links - relationship between resources
  • Operations - CRUD, FeedSync, Scripts

AtomPub is the model for the framework.

Demo

Now showing a demo of code to interact with Live Services.

SQL Server and PHP (David Sceppa, Ruwen Hess)

How did we get here?

  • Goal: Viable SQL Server connectivity for PHP
    • Support current data types and features
    • Forward thinking approach to support future features
  • Architecture: PHP driver is built on ODBC driver
    • PHP driver translates PHP API calls to ODBC API calls
  • Rich SQL Server support
    • Supports editions from Express to Enterprise
    • All SQL Server 2005 and 2008 data types supported
    • Enabling features in future SQL Server releases
      • ODBC driver updated with each release of SQL Server
      • PHP driver enables new features with less code

To RTM and beyond!

  • October 2007 - Initial CTP
  • February 2008 - 2nd CTP, API re-design
  • May 2008 - 3rd CTP, Feature complete
  • July 2008 - RTM
  • October 2008 - Cumulative Update 1

Cool features

Compiled Driver vs. Source

  • Signed, compiled driver on MSDN Download
    • Supported by Microsoft
  • Source code available on Codeplex
    • Grok the code
    • Build the driver w/ bug fixes, new features (unsupported)

This will not build or run on Linux. It relies on the ODBC driver, which is Windows-only.

Where are we going?

  • Short term
    • Improved support for SQL Server 2008 scenarios
    • Add support for key PHP driver scenarios
    • Continue to show that we’re a good citizen
  • Long term

Proposal: Scrollable results

  • Two approaches for positioning
    • Call a function to set the row position
    • Add an argument to the fetch methods
  • Feedback?

Asking for our feedback on the best approach.

Pain point: UTF-8

  • Database engine does not support UTF-8
  • Driver does not currently support UTF-8
    • Requires manual translation UTF-8 <-> UCS-2le
  • Driver could help translate
    • Easier for PHP developers
    • Still a performance hit
    • Additional work for fetch_array/object scenarios
  • Feedback?

Asking for our feedback on how the community feels about this.

What could Microsoft do to make PHP run better on Windows (Manuel Lemos)

WDS Attendee Showcase

The problems

  • PHP Windows developers face challenges that they would not face when using PHP on other platforms
  • Some PHP features do not work well on Windows
  • Some Windows specific features are not supported directly by PHP extensions
  • PHP core lacks of Windows developers
  • “PHP Windows developers are second-class citizens” —Rasmus Lerdorf

Covers a lot of classes at PHPClasses.org that solve problems he sees with PHP on Windows.

Roundtable Discussion (Lauren Cooney)

  • Lauren:

    “We want to figure out how we can best work with the PHP communities out there. I think we’ve been doing a good job, but we’re not doing a great job.”

  • Andrei:

    “Do you mean Microsoft as a whole, or individual departments/divisions within Microsoft?”

  • Lauren:

    “I think we have to think about Microsoft as a whole. […] Across the board, Microsoft is looking to be a better community citizen.”

  • Hans mentions Chris Jones as an example of excellent community support from a major company (Oracle) and how Microsoft can work better with our community by doing some of the same things Chris does.

  • Lauren:

    “I think it would be important to have someone that focuses on PHP in every single product group at Microsoft.”

  • Cal:

    “If you’re going to do that, have Joe Stagner train them. A lot of Microsoft’s effectiveness in the community is because we like Joe.”

  • Some others spoke up in agreement, saying that Microsoft needs to be “entrenched” in the community, having someone there who is a part of the community. Furthering this line of conversation, the consensus seems to be that Microsoft not only needs a “developer evangelist” who is a liaison to the community, but they need developers of various products who take part in the community.

  • Cal:

    “We want [Microsoft] at conferences for more than just sponsoring it with money. We want [Microsoft] to participate in the community.”

  • Elizabeth S.:

    In response to a discussion about Ruby, Python, etc. have various run-time environments and why PHP doesn’t. The short answer is that Ruby and Python can have other run-time environments because they have a language spec, but PHP doesn’t, so it’s more difficult to have other run-time environments.

    “[PHP] doesn’t care about a language spec. What we care about is that stuff just works.”

Written on the board

  • Participation in…
    • General participation
    • Mailing lists
    • PECL
    • Need “effective” training
    • Generally attending conferences
    • X-org MSFT PHP community leads?
  • Fear that MSFT absorbs PHP
  • Product/technologies at MSFT that PHP community wants to work with
    • COM
    • SQL Server
    • Office
    • Visual Studio (DevTools)
    • IIS
    • .NET integration

Using PHP with .NET via Phalanger (M. David Peterson)

WDS Attendee Showcase

Slides about music sharing and showing demo of amp.fm

Internet Explorer 8 and Web Standards (Chris Wilson)

Goals of IE8 Platform

  • Predictability
  • Programming Power
  • Performance

Standards – Great CSS 2.1

  • IE8 goal: complete CSS 2.1 compliance
    • Beta 2 implements every CSS 2.1 properties
  • New layout engine
    • Great typographic foundation
    • Designed with CSS 2.1 in hand
    • Clear principles: compliance & interop
    • No more hasLayout

Improving the CSS 2.1 Test Suite

  • The web needs interoperability
    • The best way to get interoperability: comprehensive unbiased test suites
  • Contributing our tests to the W3C
    • > 3200 tests contributed
    • Validates (or corrects) our interpretation
    • Goal: a complete, objective test suite

Improving Programming Predictability

  • Improved HTML interoperability
    • <object> and forms support, e.g.
  • Improved DOM compliance
    • Fixed attribute oddities
    • Many other changes – see IEBlog
  • DOM object mutability
    • getters and setters on DOM objects

Solving Web 2.0 App Problems

  • Surprise!
    • The IE6-era web app platform isn’t complete.

Web 2.0 Navigation (HTML5)

  • Set Window.location.hash, IE does the rest
    • IE fires an window.onhashchange event
    • IE updates the address bar and back button
    • Allows copy & paste of “Ajax URLs”

Querying the Element Tree

  • CSS Selector API
    • W3C Web Applications WG draft standard
    • .querySelectorAll() – returns a StaticNodeList
    • .querySelector()
    • … Missed the rest of the points.

Leveraging Local Storage

  • Web applications need local storage
    • Cookies, UserData control
  • HTML5 adds the Storage interface
    • sessionStorage (tab/session specific)
    • localStorage (shared)
    • key/value string pairs
    • 10MB per domain, 100MB total

The Network Isn’t Always There

  • Network connectivity is transient
  • HTML5 adds online/offline events
  • And a state indicator

The Mashup Dilemma

  • The most interesting web applications mash up data and components across domains
    • Without restrictions, this is unsafe
    • So today, XHR is restricted to Same Origin
  • You can circumvent this by:
    • User script (not restricted to SOP)
    • Proxying on the server side

Cross-Domain Requests

  • Cross domain requests require mutual consent between the webpage and the server
  • XDomainRequest (XDR)
    • Your app creates a XDomainRequest object
    • XDR opens a connection and requests data, sending Access Control HTTP header
    • XDR object gives your app the data IFF server responds with the proper headers
    • …

Showing code sample.

Cross-Document Messaging

  • Some scenarios want more of a “sandbox”
    • Frames are used for this today
    • but they need to add limited communication
    • Again, both sides need to opt in to be “safe”
  • postMessage/onmessage from HTML5

Making Cross-Domain Data “Safe”

  • Often the “data” passed across domain is HTML or JavaScript code, not text
  • Beta 2 has two ways to make this safe:
    • Native JSON enables safe transfer of JS object data
    • toSafeHTML() – allows any HTML to be “sanitized” (removes “active content”)

Great Accessibility

  • Unlocking Web 2.0 with W3C ARIA
    • ARIA enables accessible web 2.0 apps
    • ARIA roles, states, and properties enable assistive technology (e.g. screen readers)
  • Improved Zoom Experience

Developer Productivity Tools

  • CSS/HTML/JavaScript debugger “in the box!”
  • Debug and profile JavaScript
    • Execution control (breakpoints, step into, etc.)
    • Variable inspection (watches, locals, etc.)
    • Immediate window
    • New profiler lets you examine perf of your code
  • Debug CSS and HTML
    • View and trace effective styles
    • View layout (box model) info
    • Edit HTML and CSS live – with save to file!
    • Change browser mode and document mode

Improving Performance

  • We focus on “real-world” performance
    • MANY changes post-beta2 to improve perf
  • JavaScript improvements
    • Faster native JavaScript operations
    • Better GC, Faster DOM object lookups
    • Pre-parser doesn’t block at script tags
  • Network perf is frequently the problem
    • Connections increased to 6 (2 on modems)

Making Users More Productive

  • Users already use lots of web services
    • Maps: Windows Live, Yahoo, MapQuest
    • Blogs: Facebook, MySpace, Blogger
    • Email: Hotmail, Gmail, Yahoo
    • Productivity: …
  • But this is a manual process!

Closing Discussion with Sam Ramji

If you could ask Microsoft to change one thing and have them wave their magic wand and actually do it, what would it be?

  • Kill IE 6
  • Imdemnify open source projects from Microsoft patents
  • A GUI-less Windows server with a full-fledged shell
  • Native SSH support
  • Build Windows on top of BSD ;-)
  • Help open source projects on the legal side
  • Work more actively towards improving the patent system
  • More frankness, honesty, and openness; know when you’re wrong, admit when you’re wrong
