1、下载PHPExcel解压到extensions，修改PHPExcel/PHPExcel_Autoloader解决自动载入问题

public static function Register() {
    /*if (function_exists('__autoload')) {
        //Register any existing autoloader function with SPL, so we don't get any clashes
        spl_autoload_register('__autoload');
    }
    //Register ourselves with SPL
    return spl_autoload_register(array('PHPExcel_Autoloader', 'Load'));*/
    $functions = spl_autoload_functions();
    foreach ($functions as $function)
        spl_autoload_unregister($function);
    $functions = array_merge(array(array('PHPExcel_Autoloader', 'Load')), $functions);
    foreach ($functions as $function)
        $x = spl_autoload_register($function);
        return $x;
}	//	function Register()

2、修改config/main.php

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

3、创建components/Excel.php

class Excel
{
    private $phpExcel;

    function __construct(PHPExcel $phpExcel)
    {
        $this->phpExcel = $phpExcel;
    }

    /**
     * 根据文件名获取PHPExcel对象
     * @param $file
     * @return PHPExcel
     */
    public function getByFile($file)
    {
        $reader = PHPExcel_IOFactory::createReader('Excel5');
        $excel = $reader->load($file);
        return $excel;
    }
}

4、使用

$excel = new Excel(new PHPExcel());

:L3天

$menu = array(
  'id' => 'nav',
  'activeCssClass'=>'selected',
  'linkLabelWrapper'=>null, 
  'htmlOptions'=>array('class'=>'topNav'),
  'items'=>$items
);
$this->widget('zii.widgets.CMenu', $menu);

把这个写到view里面去
