PHP RecursiveIteratorIterator：系统找不到指定的路径？

Question

当我想用RecursiveIteratorIterator 和spl_autoload_register 自动加载类时出现此错误，

带有消息的未捕获异常“UnexpectedValueException” 'RecursiveDirectoryIterator::__construct(): 系统找不到 指定的路径。 （代码：3）

什么意思？

下面是我的类自动加载器，

function autoload_multiple_directory($class_name){

    // List all the class directories in the array.
    $array_directories = array(
        'core/controller/', 
        'core/model/',
        'core/helper/',
        'core/ext/'
    );

    $parts = explode('\\', $class_name);

    // Set the class file name.
    $file_name = end($parts).'.php';

    foreach($array_directories as $path_directory){

        $iterator = new RecursiveIteratorIterator(
            new RecursiveDirectoryIterator($path_directory),
            RecursiveIteratorIterator::SELF_FIRST
        );

        foreach ($iterator as $fileObject) {
            if ($fileObject->isDir()) {
                $files[] = str_replace('\\', '/', $fileObject->getPathname()).'/';
            }
        }


    }



    $array_directories = array_merge($array_directories,$files);

    // Loop the array.
    foreach($array_directories as $path_directory){
        if(file_exists(WEBSITE_DOCROOT.$path_directory.$file_name)){

            include WEBSITE_DOCROOT.$path_directory.$file_name;
        } 
    }
}


spl_autoload_register('autoload_multiple_directory');

错误行指向new RecursiveDirectoryIterator($path_directory),为什么？

Answer 1

我必须在new RecursiveDirectoryIterator(WEBSITE_DOCROOT.$path_directory) 中使用绝对路径，因为有时会通过 ajax 调用 init.php。
