note 107174 added to language.oop5.autoload

01 P 11PXP6 OBZ I think there shouldn't be tests in an autoload callback function, this callback will trigger because the class you're trying to load is not defined... in any case if your class is not defined, the code must fail. Therefore an autoload function should be like : spl_autoload_register(function($className) { require(str_replace('\\', '/', ltrim($className, '\\')) . '.php'); }); As the "require" function uses the include_path, the folders for the autoinclusion should be added using set_include_path, let's say your index.php is located in a "public" directory and your MVC classes are in "core", the index.php should be : define('ROOT_DIR', realpath(__DIR__ . '/..')); set_include_path(ROOT_DIR . PATH_SEPARATOR . get_include_path()); And of course you want to catch the loading errors, so you can use class_exists : $className = '\core\Controller\Hello\World'; if (!class_exists($className)) { throw new \ErrorException('Class Not Found !'); } else { $object = new $className(); } This code sample will autoload the "World.php" file located in your "core/Controller/Hello" directory, assuming that your class declaration is like : namespace core\Controller\Hello; class World { function __construct() { echo "Helloworld"; } } ---- Server IP: 69.147.83.197 Probable Submitter: 87.231.159.28 ---- Manual Page -- http://www.php.net/manual/en/language.oop5.autoload.php Edit -- https://master.php.net/note/edit/107174 Del: integrated -- https://master.php.net/note/delete/107174/integrated Del: useless -- https://master.php.net/note/delete/107174/useless Del: bad code -- https://master.php.net/note/delete/107174/bad+code Del: spam -- https://master.php.net/note/delete/107174/spam Del: non-english -- https://master.php.net/note/delete/107174/non-english Del: in docs -- https://master.php.net/note/delete/107174/in+docs Del: other reasons-- https://master.php.net/note/delete/107174 Reject -- https://master.php.net/note/reject/107174 Search -- https://master.php.net/manage/user-notes.php
