note 76577 added to language.oop5.abstract

Sometimes I wonder. PHP needs to be pushed to its limits and below everyone fails to understand what an interface is and what abstraction is. So let me make it extremely clear as I have many languages under my belt. Interfaces are in general WYSIWYG implementations of logic which in PHP are not accessible like in other languages like Java \ ASP.NET where you don't have to access the class itself...however in future I hope PHP does give us this functionality. Interfaces in PHP only define public functions without any basic or core functionality therefore making it lesser a friend to PROs from OOP && OOD backgrounds. Instead Abstraction in PHP is perfered as this allows your objects a core with the ability to define different levels of access to methods | variables | constants. Although publicly allowing access to variables (to me) | (to official \ senior programmers) defeats the whole idea of OO. Abstraction allows the keywords of final which is very important to me as I can have many child objects of objects and of child objects. Thus knowing the difference helps with your choosen style but if your really looking to make an application with Abstraction I would always suggest using an Abstract Class instead of Interfaces as Interfaces are limited and provides no functionality and is a waste of bytes on your hard drive. The below is an example of Abstraction used in an automated system. <?php Abstract Class events { protected $priority; protected $message; protected $environment; protected $syslog; protected $config; protected $global; protected $classes; protected $super; public function __construct(array &$config) { $this->config = $config; } abstract protected function writeToDatabase(Environment &$environment); abstract protected function writeToSystem(Environment &$environment); abstract protected function writeToEmail(Environment &$environment); abstract protected function writeToMobile(Environment &$environment); abstract public function execute(&$class, $method, $args); protected function environment(Exception &$object) { $this->super =& new Environment($object, $this->config); $this->global = $this->super->env(); $this->global = $this->global['environment']; return $this->super; } public function __destruct() { unset($this); } } ?> ---- Server IP: 194.145.210.3 Probable Submitter: 80.229.71.222 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.abstract.php Edit -- https://master.php.net/note/edit/76577 Del: integrated -- https://master.php.net/note/delete/76577/integrated Del: useless -- https://master.php.net/note/delete/76577/useless Del: bad code -- https://master.php.net/note/delete/76577/bad+code Del: spam -- https://master.php.net/note/delete/76577/spam Del: non-english -- https://master.php.net/note/delete/76577/non-english Del: in docs -- https://master.php.net/note/delete/76577/in+docs Del: other reasons-- https://master.php.net/note/delete/76577 Reject -- https://master.php.net/note/reject/76577 Search -- https://master.php.net/manage/user-notes.php
