thinkPHP简单调用函数与类库的方法

class IndexAction extends Action{
  public function index(){
   // 调用“扩展基类库” ThinkPHP/Extend/Library/ORG/Util/Test.class.php
   import('ORG.Util.Test');
   $test = new Test();
   // 调用“扩展基类库” ThinkPHP/Extend/Library/Com/Util/Test.class.php
   import('Com.Util.Test');
   $test = new Test();
   // 调用“核心基类库” ThinkPHP/Lib/Core/Test.class.php
   import('Think.Core.Test');
   $test = new Test();
   $this->display();
  }
}
