最近在研究PHP的Yii框架，很喜歡，碰到導出Excel的問題，研究了一下，就有了下面的方法：
1、首先在config\main.php中添加對PHPExcel的引用，我的方式是這樣：
1 2 3 4 5 6 7 8
// autoloading model and component classes
'import'=>array(
'application.models.*',
'application.components.*',
'application.extensions.phpexcel.*',
),
另外也有人用components 這個配置，但是我的有問題，所以就用上面的方法。
2、按照下面的代碼修改PHPExcel代碼目錄裡的Autoloader.php文件：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16public 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()
上面的函數中，注釋掉的是原有的代碼。
3、下面的代碼是輸出Excel，以及一些常用的屬性設置，在你的controller中：
public function actionExport()
{
$objectPHPExcel = new PHPExcel();
$objectPHPExcel->setActiveSheetIndex(0);
$page_size = 52;
//數據的取出
$model = Yii::app()->session['printdata'];
$dataProvider = $model->search();
$dataProvider->setPagination(false);
$data = $dataProvider->getData();
$count = $dataProvider->getTotalItemCount();
//總頁數的算出
$page_count = (int)($count/$page_size) +1;
$current_page = 0;
$n = 0;
foreach ( $data as $product )
{
if ( $n % $page_size === 0 )
{
$current_page = $current_page +1;
//報表頭的輸出
$objectPHPExcel->getActiveSheet()->mergeCells('B1:G1');
$objectPHPExcel->getActiveSheet()->setCellValue('B1','產品信息表');
$objectPHPExcel->setActiveSheetIndex(0)->setCellValue('B2','產品信息表');
$objectPHPExcel->setActiveSheetIndex(0)->setCellValue('B2','產品信息表');
$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.'頁');
$objectPHPExcel->setActiveSheetIndex(0)->getStyle('G2')
->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);
//表格頭的輸出
$objectPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(5);
$objectPHPExcel->setActiveSheetIndex(0)->setCellValue('B3','編號');
$objectPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(6.5);
$objectPHPExcel->setActiveSheetIndex(0)->setCellValue('C3','名稱');
$objectPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(17);
$objectPHPExcel->setActiveSheetIndex(0)->setCellValue('D3','生產廠家');
$objectPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(22);
$objectPHPExcel->setActiveSheetIndex(0)->setCellValue('E3','單位');
$objectPHPExcel->getActiveSheet()->getColumnDimension('E')->setWidth(15);
$objectPHPExcel->setActiveSheetIndex(0)->setCellValue('F3','單價');
$objectPHPExcel->getActiveSheet()->getColumnDimension('F')->setWidth(15);
$objectPHPExcel->setActiveSheetIndex(0)->setCellValue('G3','在庫數');
$objectPHPExcel->getActiveSheet()->getColumnDimension('G')->setWidth(15);
//設置居中
$objectPHPExcel->getActiveSheet()->getStyle('B3:G3')
->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
//設置邊框
$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);
//設置顏色
$objectPHPExcel->getActiveSheet()->getStyle('B3:G3')->getFill()
->setFillType(PHPExcel_Style_Fill::FILL_SOLID)->getStartColor()->setARGB('FF66CCCC');
}
//明細的輸出
$objectPHPExcel->getActiveSheet()->setCellValue('B'.($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);
//設置邊框
$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 = $n +1;
}
//設置分頁顯示
//$objectPHPExcel->getActiveSheet()->setBreak( 'I55' , PHPExcel_Worksheet::BREAK_ROW );
//$objectPHPExcel->getActiveSheet()->setBreak( 'I10' , PHPExcel_Worksheet::BREAK_COLUMN );
$objectPHPE
