Defining The Bubble

What's Happening Inside?

What Happened Outside?

PHP 5.3, 5.4, & 5.5

Massive Performance Increases PHP 5.3 significantly faster than 5.2 PHP
5.4 up to 2x as fast in some benchmarks No code changes required

PSR-0 PSR-1 and PSR-2 Standards for PHP code: • Standard
code style • Standard auto loaders & class conventions • Standard logger interfaces • Amongst others..

Namespaces Lambdas Closures Traits Generators Queues DoubleLinkedLists Heaps Stacks etc
and more

Namespaces

Lambdas & Closures // Lambdas add_action( 'the_content', function( $content ){
return $content.'Final Note'; }); // Closures $note = 'Final Note'; add_action( 'the_content', function($content) use($note) { return $content.$note; }); // anonymous functions $func = function( $content ) { return $content.'the end'; }; add_action( 'the_content', $func );

Traits Requires PHP 5.4

Speaking of Singletons...

Generators

Queues, Stacks, Sets, PriorityQueues, Heaps & other SPL containers Special
containers with performance and memory advantages over standard arrays

MySQL Removed

Replaced by PDO, MySQLi & ORMs e.g. Doctrine, Idiorm etc
WordPress hasn't moved to support these and breaks in PHP 5.5

QA Tools

PHPLOC

PHP CodeSniffer Prevent common semantic errors, and highlight coding standards
violations

PHP Mess Detector Takes a given PHP source code base
and look for several potential problems within that source. These problems can be things like: • Possible bugs • Suboptimal code • Overcomplicated expressions • Unused parameters, methods, properties

SCheck & Facebook PHP tools • Catch common mistakes such
as: function add_hash( $color ) { return '#'.$colour; } addhash(); // missing '_' • Generate databases describing your code structure for analysis • View codebases in visual tools with Google Maps style panning and zoom, and search for functions and objects

phantm Static analyser to check type in PHP code amongst
other things $dict = array(); $dict['en'] = array(); $dict['en']['fr'] = 'Bonjour'; $dict['en']['de'] = 'Hallo'; $dist['en']['it'] = 'Ciao'; $dict['en']['sp'] = 'Hola'; <input>:7 Notice: Type mismatch: expected: Array[...], found: Top $dist['en']['it'] = 'Ciao';

Invasion of the MVC Frameworks

Zend Framework

Goutte A web client/scraping library require_once '/path/to/goutte.phar'; use Goutte\Client; $client
= new Client(); $crawler = $client->request( 'GET', 'http://www.symfony-project.org/' ); $link = $crawler->selectLink('Plugins')->link(); $crawler = $client->click($link); $nodes = $crawler->filter('.error_list'); if ($nodes->count()){ die(sprintf("Authentication error: %s\n", $nodes->text())); }

Underscore.php

Assetic Asset management on steroids • Handles all assets, js/css/images/less/sass/etc
• Generic filter system for compilation/compression/URL handling amongst other things • Handles Caching & filesystem searches

Klein Superfast URL Router Library <?php require_once __DIR__ . '/vendor/autoload.php';
$klein = new \Klein\Klein(); $klein->respond('GET', '/hello-world', function () { return 'Hello World!'; }); $klein->dispatch();

Dispatch A PHP 5.3 Micro framework <?php require('../src/dispatch.php'); config('site.router', 'index.php');
get('/users', function () { echo "listing users..."; }); // get route for index get('/index', function () { echo "hello, world!\n"; });

Twig Super fast templating engine <!DOCTYPE html> <html> <head> <title>My
Webpage</title> </head> <body> <ul id="navigation"> {% for item in navigation %} <li><a href="{{ item.href }}">{{ item.caption }}</a></li> {% endfor %} </ul> <h1>My Webpage</h1> {{ a_variable }} </body> </html>
