Modern PHP, Standards, and Community

Learn how to structure and maintain a modern day PHP project using the latest standards. We'll walk through recent language improvements and how they will affect your day to day development. This will use code examples to give you in depth, real world examples of usage.

We'll also cover the latest community initiatives and standards including the PHPFIG along with the PSRs they have introduced.

14. Welcome to the Future
15. Great Scott!
16. Exceptions
18. Exceptions try { //your code goes here } catch (Exception $e) { die($e->getMessage()); }
19. Exceptions try { //your code goes here } catch (Exception $e) { die($e->getMessage()); }
20. Errors Exception implements Throwable Error implements Throwable
21. Errors try { //error thrown here } catch (Error $e) { die($e->getMessage()); }
22. Errors try { //error thrown here } catch (Error $e) { die($e->getMessage()); } catch (Exception $e) { die($e->getMessage()); }
23. Closures
25. Closures Route::get(‘/', function(){ return View::make(‘index'); });
26. Closures Route::get(‘/', function(){ return View::make(‘index'); });
27. Namespaces
29. Namespaces namespace Illuminate\Console; class Command { //…
30. Namespaces use Illuminate\Console\Command; namespace Illuminate\Console; class Command { //…
31. Namespaces use Illuminate\Console\Command; namespace Illuminate\Console; class Command { //…
32. Short Array Syntax
34. Short Array Syntax $array = array( 0 => ‘value1’, 1 => ‘value2’, );
35. Short Array Syntax $array = [ 0 => ‘value1’, 1 => ‘value2’, ];
36. Short Array Syntax $array = [ 0 => ‘value1’, 1 => ‘value2’, ];
37. Null Coalescing Operator
38. Null Coalescing $val = $_GET['val'] ?? 'default';
39. Null Coalescing $val = $_GET['val'] ?? 'default';
40. Null Coalescing $val = isset($_GET[‘val’]) ? $_GET[‘val’] : 'default';
41. Traits
42. Traits // grouping without // strict inheritance trait baseUser { function getName() { return ‘Jon Snow’; } }
43. Traits class adminUser { use baseUser; }
44. Traits $adminUser = new adminUser; echo $adminUser->getName(); //output = ‘Jon Snow’
45. PDO
47. PDO Cross System
48. PDO Cross System MS SQL MySQL Oracle PostgreSQL SQLite CUBRID Firebird Informix ODBC & DB2 4D
49. PDO Cross System Safe Binding
50. PDO $stmt = $db->prepare(‘ SELECT * FROM users WHERE id=:id ’); $stmt->bindParam(‘:id’, $id); $stmt->execute();
51. Types!
53. Scalar Type Hinting
54. Scalar Types declare(strict_types=1); function addNums(float $a, float $b) { return $a + $b; }
55. Scalar Types declare(strict_types=1); function addNums(float $a, float $b) { return $a + $b; } addNums(2, "1 week"); // Fatal error: Uncaught TypeError: Argument 2 passed to addNums() must be of the type float, string given
56. Scalar Types function addNums(float $a, float $b) addNums(2, "1 week”); // Fatal error: Uncaught TypeError: Argument 2 passed to addNums() must be of the type float, string given
57. Scalar Types try { addNums(2, "1 week”); } catch(TypeError $e) {}
58. Scalar Types try { addNums(2, 1); } catch(TypeError $e) {} //3
59. Scalar Types class/interface array callable bool float int string
60. Return Type Declarations
61. Scalar Types function addNums(float $a, float $b) : float { return $a + $b; }
62. Scalar Types function addNums(float $a, float $b) : float { return $a + $b; }
63. Scalar Types function addNums($a, $b) : int { return $a + $b; } addNums(1.5, 1); // Fatal error: Uncaught TypeError: Return value of addNums() must be of the type integer, float returned
64. Legit Tools
66. Built-in Web Server
67. Built-in Server $ php -S localhost:8000 PHP 5.7.0 Development Server started… Listening on localhost:8000 Document root is /home/ben/htdocs Press Ctrl-C to quit
68. Composer
69. Another Package Manager!?
70. Composer Sane Package Management
71. Composer Autoloading
72. Composer PEAR, ha! packagist.org
73. Composer / composer.json { "require": { "stripe/stripe-php": "dev-master", "twilio/sdk": "dev-master" } }
74. Composer $ php composer.phar update $ php composer.phar install
75. Composer $client = new Services_Twilio($sid, $tkn); $client->account ->messages ->sendMessage(…)
76. Unit Testing
78. Unit Testing PHPUnit Behat Mink Selenium CodeCeption PHPSpec
79. Unit Testing class ApiAuthTest extends PHPUnit_Framework_TestCase { public function testVerify() { $auth = new apiAuth(); $this->assertTrue($auth->verify());
80. Unit Testing class ApiAuthTest extends PHPUnit_Framework_TestCase { public function testVerify() { $auth = new apiAuth(); $this->assertTrue($auth->verify());
81. Unit Testing $ phpunit tests PHPUnit 3.3.17 by Sebastian Bergmann. Time: 0.01 seconds OK (1 tests, 1 assertions)
82. Standards
84. Standards PHP-FIG Framework Interop Group
85. Standards Member Projects Zend Symfony CakePHP Laravel SugarCRM Drupal
86. Standards PSRs PHP Standards Recommendation
87. Standards PSRs Autoloading Interfaces Style Guides
88. Standards PSRs PSR-4: Autoloading PSR-1: Basic Coding Standards PSR-2: Coding Style Guide PSR-7: HTTP Message Interface PSR-6: Caching Interface PSR-3: Logger Interface
89. Standards PSR-4 Auto-loading Replaces PSR-0 Used by Composer
90. Standards $client = new Services_Twilio($sid, $tkn); $client->account ->messages ->sendMessage(…)
91. Standards PSR-1 Basic Coding Styles Generally accepted Not very opinionated
92. Standards PSR-1 Basic Coding Styles camelCasing Opening Tags Namespacing Class Names UTF-8
93. Standards PSR-2 Coding Style Guide Greater Detail Opinionated
