[英]Using spl_autoload_register
Must I put the following lines in each PHP file I create to use autoloader? 我必须在创建的每个PHP文件中放入以下行以使用自动加载器吗? Or there is a solution to do it once, inside "index.php" of the application for example, and instantiate the classes in other files like usual?
还是有一种解决方案,例如在应用程序的“ index.php”内部执行一次,然后像往常一样实例化其他文件中的类?
function autoload($class) {
require('/path/to/mylibrary/' . str_replace('_', '/', $class) . '.php');
}
spl_autoload_register('autoload');
Thanks. 谢谢。
You add these lines once. 您添加这些行一次。 The rest of the request your autoload-function will be used to load the class-files.
请求的其余部分将使用autoload-function来加载类文件。 You should put this somewhere at the start of your php, for example in the index.php.
您应该将其放在php的开头,例如在index.php中。 But if you have multiple entry-points (for example http://www.example.com/index.php and http://www.example.com/page.php ) all these files should have the
spl_autoload_register
(either via copy-paste but more preferable via an include(..)
). 但是,如果您有多个入口点(例如http://www.example.com/index.php和http://www.example.com/page.php ),则所有这些文件都应具有
spl_autoload_register
(可以通过复制-paste,但更可取的是通过include(..)
)。
