本文实例讲述了yii框架使用phpexcel导出excel文件的方法。分享给大家供大家参考，具体如下：
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：
// 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：
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：
/*
导出为excel
*/
public function actionexport()
{
$objectphpexcel = new phpexcel();
$objectphpexcel->setactivesheetindex(0);
$page_size = 52;
//数据的取出
$model = yii::app()->session['printdata'];
$dataprovider = $model->search();
$dataprovider->setpagination(false);
$data = $dataprovider->getdata();
$count = $dataprovider->gettotalitemcount();
//总页数的算出
$page_count = (int)($count/$page_size) +1;
$current_page = 0;
$n = 0;
foreach ( $data as $product )
{
if ( $n % $page_size === 0 )
{
$current_page = $current_page +1;
//报表头的输出
$objectphpexcel->getactivesheet()->mergecells('b1:g1');
$objectphpexcel->getactivesheet()->setcellvalue('b1','产品信息表');
$objectphpexcel->setactivesheetindex(0)->setcellvalue('b2','产品信息表');
$objectphpexcel->setactivesheetindex(0)->setcellvalue('b2','产品信息表');
$objectphpexcel->setactivesheetindex(0)->getstyle('b1')->getfont()->setsize(24);
$objectphpexcel->setactivesheetindex(0)->getstyle('b1')
->getalignment()->sethorizontal(phpexcel_style_alignment::horizontal_center);
$objectphpexcel->setactivesheetindex(0)->setcellvalue('b2','日期：'.date("y年m月j日"));
$objectphpexcel->setactivesheetindex(0)->setcellvalue('g2','第'.$current_page.'/'.$page_count.'页');
$objectphpexcel->setactivesheetindex(0)->getstyle('g2')
->getalignment()->sethorizontal(phpexcel_style_alignment::horizontal_right);
//表格头的输出
$objectphpexcel->getactivesheet()->getcolumndimension('a')->setwidth(5);
$objectphpexcel->setactivesheetindex(0)->setcellvalue('b3','编号');
$objectphpexcel->getactivesheet()->getcolumndimension('b')->setwidth(6.5);
$objectphpexcel->setactivesheetindex(0)->setcellvalue('c3','名称');
$objectphpexcel->getactivesheet()->getcolumndimension('c')->setwidth(17);
$objectphpexcel->setactivesheetindex(0)->setcellvalue('d3','生产厂家');
$objectphpexcel->getactivesheet()->getcolumndimension('d')->setwidth(22);
$objectphpexcel->setactivesheetindex(0)->setcellvalue('e3','单位');
$objectphpexcel->getactivesheet()->getcolumndimension('e')->setwidth(15);
$objectphpexcel->setactivesheetindex(0)->setcellvalue('f3','单价');
$objectphpexcel->getactivesheet()->getcolumndimension('f')->setwidth(15);
$objectphpexcel->setactivesheetindex(0)->setcellvalue('g3','在库数');
$objectphpexcel->getactivesheet()->getcolumndimension('g')->setwidth(15);
//设置居中
$objectphpexcel->getactivesheet()->getstyle('b3:g3')
->getalignment()->sethorizontal(phpexcel_style_alignment::horizontal_center);
//设置边框
$objectphpexcel->getactivesheet()->getstyle('b3:g3' )
->getborders()->gettop()->setborderstyle(phpexcel_style_border::border_thin);
$objectphpexcel->getactivesheet()->getstyle('b3:g3' )
->getborders()->getleft()->setborderstyle(phpexcel_style_border::border_thin);
$objectphpexcel->getactivesheet()->getstyle('b3:g3' )
->getborders()->getright()->setborderstyle(phpexcel_style_border::border_thin);
$objectphpexcel->getactivesheet()->getstyle('b3:g3' )
->getborders()->getbottom()->setborderstyle(phpexcel_style_border::border_thin);
$objectphpexcel->getactivesheet()->getstyle('b3:g3' )
->getborders()->getvertical()->setborderstyle(phpexcel_style_border::border_thin);
//设置颜色
$objectphpexcel->getactivesheet()->getstyle('b3:g3')->getfill()
->setfilltype(phpexcel_style_fill::fill_solid)->getstartcolor()->setargb('ff66cccc');
}
//明细的输出
$objectphpexcel->getactivesheet()->setcellvalue('b'.($n+4) ,$product->id);
$objectphpexcel->getactivesheet()->setcellvalue('c'.($n+4) ,$product->product_name);
$objectphpexcel->getactivesheet()->setcellvalue('d'.($n+4) ,$product->product_agent->name);
$objectphpexcel->getactivesheet()->setcellvalue('e'.($n+4) ,$product->unit);
$objectphpexcel->getactivesheet()->setcellvalue('f'.($n+4) ,$product->unit_price);
$objectphpexcel->getactivesheet()->setcellvalue('g'.($n+4) ,$product->library_count);
//设置边框
$currentrownum = $n+4;
$objectphpexcel->getactivesheet()->getstyle('b'.($n+4).':g'.$currentrownum )
->getborders()->gettop()->setborderstyle(phpexcel_style_border::border_thin);
$objectphpexcel->getactivesheet()->getstyle('b'.($n+4).':g'.$currentrownum )
->getborders()->getleft()->setborderstyle(phpexcel_style_border::border_thin);
$objectphpexcel->getactivesheet()->getstyle('b'.($n+4).':g'.$currentrownum )
->getborders()->getright()->setborderstyle(phpexcel_style_border::border_thin);
$objectphpexcel->getactivesheet()->getstyle('b'.($n+4).':g'.$currentrownum )
->getborders()->getbottom()->setborderstyle(phpexcel_style_border::border_thin);
$objectphpexcel->getactivesheet()->getstyle('b'.($n+4).':g'.$currentrownum )
->getborders()->getvertical()->setborderstyle(phpexcel_style_border::border_thin);
$n = $n +1;
}
//设置分页显示
//$objectphpexcel->getactivesheet()->setbreak( 'i55' , phpexcel_worksheet::break_row );
//$objectphpexcel->getactivesheet()->setbreak( 'i10' , phpexcel_worksheet::break_column );
$objectphpexcel->getactivesheet()->getpagesetup()->sethorizontalcentered(true);
$objectphpexcel->getactivesheet()->getpagesetup()->setverticalcentered(false);
ob_end_clean();
ob_start();
header('content-type : application/vnd.ms-excel');
header('content-disposition:attachment;filename="'.'产品信息表-'.date("y年m月j日").'.xls"');
$objwriter= phpexcel_iofactory::createwriter($objectphpexcel,'excel5');
$objwriter->save('php://output');
}
代码执行后，会直接生成excel，并提示下载或打开。
