Small RantNew Frameworks & LibrariesGitHub Commercial BreakBest PracticesComposerWishful Thinking

A bit of history

PHP4 - 22-May-200001 class Foo_Bar_Baz02 {03 var $foo;04 05 function Foo_Bar_Baz()06 {07 }08 09 function bar()10 {11 }12 }

PHP5 - 13-Jul-200401 class Foo_Bar_Baz02 {03 public $foo;04 05 public function __construct()06 {07 }08 09 private function bar()10 {11 }12 }

Could you spot the differences?

Yet seven years later~20% of servers still run PHP4

Source: @iliaa's PHP Advent article, December 2010.

PHP5.3 - 30-Jun-200901 namespace Foo\Bar;02 03 class Baz04 {05 public $foo;06 07 public function __construct()08 {09 }10 11 private function bar()12 {13 }14 }

Again, not much has changed.But it changes everything.

Backslash\Means\No\Backwards\Compatibility

We've been sitting on our assesfor too long.

It's time for a change.

New Frameworks

Symfony2LithiumSilexZF2....

New Libraries

AsseticAsset management & processing

Combine & Compress JS, CSSCompile CoffeeScript, SASS, LESS, ..Re-encode imagesAll on the fly with cache or pre-processedInspired by Python's WebAssetsShipped with Symfony2

http://github.com/kriswallsmith/assetic

Doctrine2DBAL, ORM, ODMs

Document stores (MongoDB, CouchDB,PHPCR, XML)Common interfaces allow for interop andknowledge re-usePropel2 builds on top of itShipped with Symfony2

http://github.com/doctrine

MonologLogging

FingersCrossedHandler for productionLog to files, FirePHP, emails, etc.Inspired by Python's LogbookShipped with Symfony2

http://github.com/Seldaek/monolog

TwigTemplate engine

Automatic escapingSeparation of concerns(Readability)Inspired by Python's Jinja2Shipped with Symfony2

http://github.com/fabpot/Twig

GaufretteFilesystem abstraction

Code once, store files anywhereS3, Memory, FTP, Rackspace, ..Transparently cache calls to slow backends

http://github.com/knplabs/Gaufrette

SnappyGenerates PDF/images from webpages

Uses wkhtmltopdf/wkhtmltoimageGood example of a small single-purposelibrary

http://github.com/knplabs/snappy

ImagineImage manipulation

API that doesn't suckSupports GD2, Imagick, GmagickEasily resize, crop, and moreInspired by Python's PIL & others

http://github.com/avalanche123/Imagine

BuzzHTTP requests

API that doesn't suckWraps around CURL

http://github.com/kriswallsmith/Buzz

GoutteWeb Crawler

Supports CSS3 selectors to extract contentEasily follow links, submit forms, etc.Good example of code re-use (Sf2/ZF2components)

http://github.com/fabpot/Goutte

I can't list them all.

GitHub

Git will hurt youRead http://progit.org - it's free.

GitHub is your friend

No need to track down a developer'semail. Hit fork, create a branch, then senda pull requestPush code, get immediate attention andcontributorsREADME.mdown in every repository200 Symfony2 contributors, still in beta!

Best Practices

MIT LicenseFree as in free.

Autoload with PSR-0

http://tinyurl.com/psr0-standard

01 // One class per file02 // First bit should be a vendor name (your project, company, ..)03 // This should sit in <project>/Nelmio/Bar/Baz.php04 // WATCH THE CASE!05 06 namespace Nelmio\Bar;07 08 class Baz09 {10 }

PEAR-style Coding Standards

http://pear.php.net/manual/en/standards.php

01 namespace Foo\Bar;02 03 class Baz04 {05 public $foo;06 07 public function __construct()08 {09 $stuff = array('Coding Style');10 if (true) {11 foreach ($stuff as $blob) {12 echo "happy $blob!";13 }14 } else {15 echo "dead kittens";16 }17 }18 }

Remember, kids, standardsare NOT about taste

Testing

Tests are always good, but for librariesthey're a must.Typing phpunit in <project>/ is all I wantto know.

Composer

Package Management for PHP

Mostly inspired by npm and bundlerAdvanced dependency resolvingInstall project dependencies locally

Compose great things with small libraries

Rely on proven code to do common tasksSimplify old APIs (e.g. Imagine, Buzz)

composer.json (lib)01 {02 "name": "Monolog",03 "description": "Logging for PHP 5.3",04 "keywords": ["log","logging"],05 "homepage": "http://github.com/Seldaek/monolog",06 "version": "1.0.0",07 "license": "MIT",08 "authors": [09 {10 "name": "Jordi Boggiano",11 "email": "j.boggiano@seld.be",12 "homepage": "http://seld.be"13 }14 ],15 "require": {16 "php": ">=5.3.0"17 }18 }

composer.json (project)01 {02 "repositories": {03 "AwesomeLib": {04 "git": "git://github.com/Jim/AwesomeLib.git"05 },06 "GreatLib": {07 "git-bare": {08 "url": "git://github.com/Bob/GreatLib.git",09 "version": "1.0.0"10 }11 }12 },13 "require": {14 "Twig": ">=1.0.0",15 "AwesomeLib": "latest",16 "GreatLib": "1.0.0",17 "Monolog": "latest"18 }19 }

Demo, kind of.(blame @naderman :)

Fear code re-use no more.

Last words

Namespace adoption, in effect,opens up a world of

possibilities.

Open up your mind, we're not alone.

Share your codeand collaborate.

Thank you.
