Yii中的自动加载问题

Question

I put password.php file in components folder. In phpStorm existing functions in the password.php are shown well(auto-completion), but when running encountered with this:

Fatal error: Call to undefined function password_hash() in . . .\protected\controllers\SiteController.php on line 129

What's the reason?

main.php

...
'import'=>array(
    'application.models.*',
    'application.components.*',
),
...

Yii only autoloads classes if file name is same as class name and and if class definition file is in import path. For file containing bundle of functions you have to include (or require) it manually.
To include you could use dirname(__FILE__) (php 5.2) or __DIR__ (php 5.3+) to get path to current file, and then append relative path to your file and file name. You could put this in index.php, something like that:

require_once dirname(__FILE__) . '/../protected/components/password.php';

or more simply if you have php 5.3+:

require_once __DIR__ . '/../protected/components/password.php';
