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：

// autoloading model and component classes

'import'=>array(

'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() {

$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：

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)->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;
