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：

     /*

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114
