16. WHY YOU SHOULD CHOOSE PHP?
17. HOSTING Shared VPS Dedicated servers Heroku Google App Engine Azure
18. POPULARITY - TIOBE INDEX
19. Popularity - usage of languages on web
20. COMMUNITY More than 5 millions PHP developers worldwide Up to thousand PHP developers in Serbia
21. ACTIVITY
24. Simplicity - Highly learnable The easiest language to learn for non-technical people Fast and reliable Platform independent Bunch of good tools Bunch of extensions Good (and extensive) documentation Big players involved (FB...) Open source Lets you get things done
25. PREJUDICE <!--?php $db = connect_mysql('192.168.1.1', 'root' , 'secretPassword123' ); $item = get_mysql_data('SELECT * FROM my_table WHERE id= $_GET['id' ?--> <title><?php echo $item['title'];?></title> <div> <!--?php $users = get_mysql_data('SELECT * FROM users WHERE bla = '.$ite ?--> <!--?php foreach($users as $user){ ?-->
26. Tim Bray “All the PHP code I’ve seen in that experience has been messy, unmaintainable crap. Spaghetti SQL wrapped in spaghetti PHP wrapped in spaghetti HTML, replicated in slightly- varying form in dozens of places”
27. namespace League\Flysystem; use LogicException; use InvalidArgumentException; class Filesystem implements FilesystemInterface { // variable declaration hidden in this example /** * Constructor * * @param AdapterInterface $adapter * @param mixed $config */ public function __construct(AdapterInterface $adapter, $config = null)
28. EDUCATION
29. PHP THE RIGHT WAY
30. LARACAST
31. BOOKS http://php-books.com/
35. CONFERENCES
36. PHP FIG PHP Framework Interop Group
38. PSR Php Standard Recommendation PSR-0 - Autoloading standard PSR-1 - Basic coding standard PSR-2 - Coding style guide PSR-3 - Logger interface PSR-4 - Improved autoloading PSR-5 - PHPDoc PSR-6 - Cache interface PSR-7 - HTTP message implementation
39. COMPOSER Dependency Manager for PHP Created by Jordi Boggiano and Nils Adermann Thank you guys!
40. Fabien Potencier “PHP has a better dependency manager than any other languages”
41. curl -sS https://getcomposer.org/installer | php Can be installed globally and locally
42. The problem that Composer solves is this: You have a project that depends on a number of libraries Some of those libraries depend on other libraries You declare the things you depend on Composer finds out which versions of which packages need to be installed, and installs them (meaning it downloads them into your project)
43. Declaring dependencies composer.json { "name": "zendframework/skeleton-application", "description": "Skeleton Application for ZF2", "license": "BSD-3-Clause", "keywords": [ "framework", "zf2" ], "homepage": "http://framework.zend.com/", "require": { "php": ">=5.3.3", "zendframework/zendframework": "2.2.*", "aws/aws-sdk-php-zf2": "1.2.1", "league/flysystem": "0.4.*@dev" } }
45. SEMANTIC VERSIONING more info - http://semver.org/
46. VERSION CONSTRAINTS
47. EXACT MATCH 1.0.0, dev-master
48. WILDCARD RANGE 1.0.*, 2.*
49. HYPHEN RANGE 1.0 - 2.0 === >=1.0.0 < 2.1 1.0.0 - 2.1.0 === >=1.0.0 <= 2.1.0
50. UNBOUNDED RANGE >= 1.0 DO NOT USE THIS
51. NEXT SIGNIFICANT RELEASE ~1.2 === >=1.2.0 <2.0.0 ~1.2.3 === >=1.2.3 <1.3.0
52. CARET / SEMVER OPERATOR ^1.2.3 === >=1.2.3 <2.0.0 ^ 0.3 === >=0.3.0 <0.4.0 Libraries should use ^ and you should too!
53. THE LOCK FILE composer.lock Provide fast installs with low memory usage Reproducible installs Do you add it to .gitignore? Commit it and use it with composer install
54. DO NOT DEPLOY IT
55. AUTOLOADING You don’t have to maintain your own autoloader Ability to load your code automatically include "vendor/autoload.php";
56. "autoload": { "psr-0" : { "Application": "src/" } }
57. "autoload": { "psr-4" : { "Application\\": "src/" } }
58. "autoload": { "classmap" : [ "src/" ] }
59. <!--?php // autoload_classmap.php @generated by Composer $vendorDir = dirname(dirname(__FILE__)); $baseDir = dirname($vendorDir); return array( 'Application\\Controller\\Dashboard' =--> $baseDir . '/src/Application/Cont 'Application\\Controller\\Defaults' => $baseDir . '/src/Application/Control 'Application\\Controller\\Entry' => $baseDir . '/src/Application/Controller 'Application\\Controller\\Logbook' => $baseDir . '/src/Application/Controll 'Application\\Controller\\RequiresAuth' => $baseDir . '/src/Application/Con 'Application\\Controller\\User' => $baseDir . '/src/Application/Controller/ 'Application\\Model\\LogEntry\\Defaults' => $baseDir . '/src/Application/Mo 'Application\\Model\\LogEntry\\Gateway' => $baseDir . '/src/Application/Mod
60. { "require": { "vendor/package": "1.3.2", "vendor/package2": "1.*", "vendor/package3": ">=2.0.3" } }
61. PACKAGIST STATISTICS - MAY 2014 29 908 packages registered 110 247 versions available 207 357 630 packages installed (since 2012-04-13)
62. PACKAGIST STATISTICS - APRIL 2015 56 164 packages registered 246 789 versions available 687 988 359 packages installed (since 2012-04-13)

67. BEFORE YOU CHOOSE PACKAGE Check if it is properly tested Check documentation (README.md) Check Stability dev -> alpha -> beta -> RC -> stable Check number of downloads Check when it was last authored Check the licence
68. PHP FRAMEWORKS
69. Zend Framework 2 Symfony 2 Laravel 4, 5 Yii 2 CakePHP 3 Aura
70. PhalconPhp Slim Silex Lumen
72. TAKE CARE ABOUT THIS What do you want to build? Is good documentation available? Is it worth the investment? Community Comparing with other FW Check the licence Security
73. 3 DONT'S Don't spend countless hours in search of the „best“ framework. There is no such thing! Don't get religious with a language / framework / whatever! Don't decide based on stupid „hello world“ benchmarks.
74. SYMFONY 2 “If you have a PHP problem the Symfony community has already solved it”
77. There is bundle for everything Integrates with Doctrine, Propel, PHPUnit ... Aims to speed up the creation and maintenance of web applications Aim at building enterprise-level applications, giving developers full control over the configuration
79. LARAVEL The Swiss-Knife of Startup world The Most Popular FW of 2015 FW with the best marketing
80. Symfony components used by Laravel
81. Database agnostic migrations and schema builder Great ORM - Eloquent Painless routing Blade Templating Engine Powerful queue library Validation Built with testing in mind
82. LARAVEL ECOSYSTEM Forge Homestead Elixir Envoyer Laracast
83. PHALCONPHP "The fastest framework"
84. Implemented as a C extension Learning curve is pretty easy Support Micro and Macro application Loosely coupled to allow developers to use the whole framework or selected objects Neat and clean intuitive API with solid code written on powerful design patterns
86. PHP IS NOT FOR Building command line apps Doing heavy calculation Calculate statistics You need all the performance you can get
