包括Yii中的外部库

Question

How can I call these library functions from anywhere in my Yii app? I have a library:

#mylib.php

<?php
class MyLib {
    public function foo()
    {
        echo "hello!";
    }
}

and want to be able to call this function throughout my Yii app:

MyLib::foo();

I don't know where to place my library or how/where to import it. This is just an example of what I'm trying to do but I am trying to make a library that has multiple namespaces so I can access the library and have access to all the namespaces after importing it.

There are several ways.

1. Register libraries' autoloader:

   // Enable Zend autoloader
   spl_autoload_unregister(array('YiiBase', 'autoload')); // Disable Yii autoloader
   Yii::import('site.common.lib.*'); // Add Zend library to include_path
   Yii::import('site.common.lib.Zend.Loader.Autoloader', true); // Require Zend autoloader
   spl_autoload_register(array('Zend_Loader_Autoloader', 'autoload')); // Register Zend autoloader
   spl_autoload_register(array('YiiBase', 'autoload')); // Register Yii autoloader
   

2. Add library to the import section in your config/main.php:

   return array(           
       // Autoloading
       'import' => array(
           'application.lib.*',
           'application.components.*',
           'site.common.extentions.YiiMongoDbSuite.*',
       ),
   );
   

3. Autoloading anywhere in your application:

   Yii::import('application.lib.*');
