51. A Talk About Naming Things Talk Dutch PHP UnCon 2015 Namespacing by Type
53. use Entities\Member; use Entities\Policy; use DTOs\BuyInsurancePolicy; use Repositories\CustomerRepository; use Repositories\PolicyRepository; use ValueObjects\Money; use ValueObjects\Currency; So, I heard you like namespace imports...
54. A Talk About Naming Things Talk Dutch PHP UnCon 2015 Let’s talk about Cohesion!
55. 1 2 3 4 5 x a b c i j $ % . ;
56. $i = 0;
57. $i = 0; while ($i < 1) { $i--; }
58. function liveForever() { $i = 0; while ($i < 1) { $i--; } }
59. class Member { public static function register() {} public function unregister() {} public function reregister() {} }
60. What’s Next?
61. Member.php class Member { public static function register() {} public function unregister() {} public function reregister() {} }
62. Member.php class Member { public static function register() {} public function unregister() {} public function reregister() {} } class MemberOnlyRegisteredOnce extends \Exception {};
63. namespace WhatIsANamespaceReally? { class Member { public static function register() {} public function unregister() {} public function reregister() {} } class MemberOnlyRegisteredOnce extends \Exception {}; function functions_toooooooooo() {} }
