The Great Framework Kumbaya

Time to gather our frameworks around a warm camp fire and see just how much we have in common In this presentation, we take a flat PHP4-style application and gently migrate it into our own "framework", that uses components from Symfony2, Zend Framework 2, Aura and a library called Pimple. By the end, you'll see how any ugly application can take advantage of the many wonderful tools available to PHP developers. You'll also learn exactly how *any* framework actually works under the hood by hooking up routing, controllers, services and events.

2. KnpUniversity.com github.com/weaverryan Who is this Happy Camper? > Lead for the Symfony documentation
 > KnpLabs US - Symfony Consulting, training, Kumbaya ! > Writer for KnpUniversity.com Tutorials > Husband of the much more talented @leannapelham
3. ! Personal Homepage
6. Yep, that’s a sausage hat wink wink that’s me! @jmikola
7. http://bit.ly/php-camp @weaverryan
8. Open our Database connection // index.php
9. Try to get a clean URI // index.php
10. Render the homepage // index.php
11. List our happy campers! // index.php
12. Why don’t we code like this anymore?
13. The Tribes of PHP meet the UN
14. Formerly Solar
15. > The United Nations of PHP ! > Equally Important ! > Equally dysfunctional (like any happy family) @weaverryan
17. FIG != collaboration
18. FIG Empowers You…
19. To become best friends with all the frameworks
20. A) Reading request info could be better ! B) can’t set headers later on ! C) front controller ! D) little URL control ! E) all objects are global ! F) 1 giant file (no separation) ! G) HTML and PHP is mixed! Problems @weaverryan
21. ! $_SERVER[‘HOST'] ! header('X-POWERED-BY: crap');
24. composer require symfony/http-foundation … used by Laravel, Silex, Symfony, Drupal 8…
25. Current Status @weaverryan
26. WOW!
27. ... becomes ... The “Request” object
28. ... becomes ... The “Request” object
29. ... becomes ... The “Response” object
30. ! if ($url == '/') {
31. if ($uri == '/' || $uri == '') { // ... } elseif ($uri == '/attendees') { // ... } else { // ... } @weaverryan Our app is a giant gross “if” statement Problems Grabbing a piece from the URL like /blog/my-blog-post will take some work
32. Aura.Router
33. composer require aura/router First composer require
34. Then Celebrate!
35. @weaverryan Current Status
36. 1) Map URI to “controller”
40. 2) Execute the controller* * each controller is a flat function
41. The Controllers
42. $kitten--
43. 1. Request cleans the URI 2. Router matches the URI to a route, returns a 
 “controller” string 3. We execute the controller function 4. The controller creates a Response object 5. We send the Response headers and content The Big Picture @weaverryan
44. our 20 line framework solves…
45. A) Reading request info could be better ! B) can’t set headers later on ! C) front controller ! D) little URL control ! E) all objects are global ! F) 1 giant file (no separation) ! G) HTML and PHP is mixed! Problems @weaverryan
46. ! Global objects are universally hated
47. > We’ve got lots of random, disorganized objects floating around and some depend on others Problems > And we can’t easily access them from within our controllers @weaverryan
48. Pimple! … used by Silex … name loved by ???
49. composer require pimple/pimple First composer require
50. Then Celebrate!
51. Centralize the db connection
52. Centralize the db connection
53. Pass the container to the controller
54. $kitten++
55. Container all the things!
58. With everything in the container, our “framework” just got skinny
61. ! Tackling Disorganization
62. We have 1 file with everything mixed ! ! 1) Creation of container & objects 2) Definition of routes 3) Definition of controllers 4) The “framework” code that executes everything Problems @weaverryan
63. We have 1 file with everything mixed ! 1) services.php 2) routes.php 3) controllers.php 4) bootstrap.php (framework code) Basic Solution @weaverryan
64. index.php Nothing to see here...
65. bootstrap.php …
66. services.php
67. routing.php
68. controllers.php
69. bootstrap.php … all the same “stuff”…
70. All Frameworks Work Like This
73. ! <h1><?php $crap; ?></h1>
74. Problems @weaverryan bleh!
75. composer require twig/twig First composer require
76. Then Celebrate!
77. Before
78. After
79. views/attendees.twig
80. Getting kinda easy, right?
81. What’s available? Search GitHub!
82. All Your Frameworks Are Belong to Us
83. To focus on the interesting problems… ! (business problems)
84. … we need to remove the boring, repetitive problems…
85. … but don’t limit yourself to one “world”… Symfony Developer Laravel Developer Drupal Developer Silex Developer
86. … be a PHP Developer
87. Thanks!
