phpexcel 使用一,解决自动加载问题

Yii框架中使用PHPExcel导出Excel文件

最近在研究PHP的Yii框架，很喜欢，碰到导出Excel的问题，研究了一下，就有了下面的方法：

 

1、首先在config\main.php中添加对PHPExcel的引用，我的方式是这样：

1
2
3
4
5
6
7
8
// autoloading model and component classes
    'import'=>array(
        /*'application.modules.srbac.controllers.SBaseController',*/       
        'application.models.*',
        'application.components.*',
        'application.extensions.phpexcel.*',
           
    ),

另外也有人用components 这个配置，但是我的有问题，所以就用上面的方法。

 

2、按照下面的代码修改PHPExcel代码目录里的Autoloader.php文件：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
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()

上面的函数中，注释掉的是原有的代码。

 

3、下面的代码是输出Excel，以及一些常用的属性设置，在你的controller中：

     /*
