Yaf_Loader::import — Load a PHP script

Açıklama

public static function Yaf_Loader::import(string $file): bool

Load a PHP script file once. If the file is not an absolute path, it is looked up under the local library directory.

A file is only included once; calling Yaf_Loader::import() again with the same file returns true without re-including it.

Bağımsız Değişkenler

file: The file to load.
