Modern PHP, Standards, and Community (phpDay 2017)

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.

15. Welcome to the Future
16. Great Scott!
17. Exceptions
19. Exceptions try { //your code goes here } catch (Exception $e) { die($e->getMessage()); }
20. Exceptions try { //your code goes here } catch (Exception $e) { die($e->getMessage()); }
21. Errors Exception implements Throwable Error implements Throwable
22. Errors try { //error thrown here } catch (Error $e) { die($e->getMessage()); }
23. Errors try { //error thrown here } catch (Error $e) { die($e->getMessage()); } catch (Exception $e) { die($e->getMessage()); }
24. Errors try { //err or excpt thrown here } catch (Throwable $t) { die($t->getMessage()); }
25. PDO
27. PDO Cross System
28. PDO Cross System MS SQL MySQL Oracle PostgreSQL SQLite CUBRID Firebird Informix ODBC & DB2 4D
29. PDO Cross System Safe Binding
30. PDO $stmt = $db->prepare(‘ SELECT * FROM users WHERE id=:id ’); $stmt->bindParam(‘:id’, $id); $stmt->execute();
31. Closures
33. Closures Route::get(‘/', function(){ return View::make(‘index'); });
34. Closures Route::get(‘/', function(){ return View::make(‘index'); });
35. Namespaces
37. Namespaces namespace Illuminate\Console; class Command { //…
38. Namespaces use Illuminate\Console\Command; namespace Illuminate\Console; class Command { //…
39. Namespaces use Illuminate\Console\Command; namespace Illuminate\Console; class Command { //…
40. Short Array Syntax
42. Short Array Syntax $array = array( 0 => ‘value1’, 1 => ‘value2’, );
43. Short Array Syntax $array = [ 0 => ‘value1’, 1 => ‘value2’, ];
44. Short Array Syntax $array = [ 0 => ‘value1’, 1 => ‘value2’, ];
45. Traits
46. Traits // grouping without // strict inheritance trait baseUser { function getName() { return ‘Jon Snow’; } }
47. Traits class adminUser { use baseUser; }
48. Traits $adminUser = new adminUser; echo $adminUser->getName(); //output = ‘Jon Snow’
49. Passwords
50. Passwords //safe password hashing password_hash($_POST['pass'], ALGO);
51. Passwords //safe password hashing password_hash($_POST['pass'], ALGO); //password verification password_verify($_POST['pass'], $u->pass);
52. Passwords //safe password hashing password_hash($_POST['pass'], ALGO); //password verification password_verify($_POST['pass'], $u->pass); //password rehashing password_needs_rehash($u->pass, ALGO);
53. Passwords if (password_verify($_POST['pass'], $u->pass)) { if (password_needs_rehash( $u->pass, PASSWORD_DEFAULT )) { $u->pass = password_hash( $_POST['pass'], PASSWORD_DEFAULT ); $u->save();
54. Null Coalescing Operator
55. Null Coalescing $val = $_GET['val'] ?? 'default';
56. Null Coalescing $val = $_GET['val'] ?? 'default';
57. Null Coalescing $val = isset($_GET[‘val’]) ? $_GET[‘val’] : 'default';
58. Types!
60. Scalar Type Hinting
61. Scalar Types declare(strict_types=1); function addNums(float $a, float $b) { return $a + $b; }
62. 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
63. 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
64. Scalar Types try { addNums(2, "1 week”); } catch(TypeError $e) {}
65. Scalar Types try { addNums(2, 1); } catch(TypeError $e) {} //3
66. Scalar Types class/interface array callable bool float int string
67. Return Type Declarations
68. Scalar Types function addNums(float $a, float $b) : float { return $a + $b; }
69. Scalar Types function addNums(float $a, float $b) : float { return $a + $b; }
70. Scalar Types function addNums($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
71. Legit Tools
73. Built-in Web Server
74. 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
75. Composer
76. Another Package Manager!?
77. Composer Sane Package Management
78. Composer Autoloading
79. Composer PEAR, ha! packagist.org
80. Composer / composer.json { "require": { "stripe/stripe-php": "dev-master", "twilio/sdk": "dev-master" } }
81. Composer $ php composer.phar install -> composer.lock
82. Composer $ php composer.phar install -> composer.lock Commit it ^
83. Composer $ php composer.phar install /composer.lock
84. Composer $ php composer.phar update /composer.json
85. Composer $client = new Services_Twilio($sid, $tkn); $client->account ->messages ->sendMessage(…)
86. Unit Testing
88. Unit Testing PHPUnit Behat Mink Selenium CodeCeption PHPSpec
89. Unit Testing class ApiAuthTest extends PHPUnit_Framework_TestCase { public function testVerify() { $auth = new apiAuth(); $this->assertTrue($auth->verify());
90. Unit Testing class ApiAuthTest extends PHPUnit_Framework_TestCase { public function testVerify() { $auth = new apiAuth(); $this->assertTrue($auth->verify());
91. Unit Testing $ phpunit tests PHPUnit 3.3.17 by Sebastian Bergmann. Time: 0.01 seconds OK (1 tests, 1 assertions)
92. Standards
94. Standards PHP-FIG Framework Interop Group
95. Standards Member Projects Zend Symfony CakePHP Magento Joomla Drupal
96. Standards PSRs PHP Standards Recommendation
97. Standards PSRs Autoloading Interfaces Style Guides
98. 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
99. Standards PSR-4 Auto-loading Replaces PSR-0 Used by Composer
100. Standards $client = new Services_Twilio($sid, $tkn); $client->account ->messages ->sendMessage(…)
101. Standards PSR-1 Basic Coding Styles Generally accepted Not very opinionated
102. Standards PSR-1 Basic Coding Styles camelCasing Opening Tags Namespacing Class Names UTF-8
103. Standards PSR-2 Coding Style Guide Greater Detail Opinionated
104. Standards PSR-2 Coding Style Guide Spacing Braces Lines Keywords Bools Control Struct
105. Standards PSR-7 HTTP Message Interface Requests Responses
