运用PHPExcel导入导出excel格式文件

//设置环境变量（新增PHPExcel）
set_include_path('.'. PATH_SEPARATOR . Yii::app()->basePath.'/lib/PHPExcel' . PATH_SEPARATOR . get_include_path());
//注：在yii中，也可以直接Yii::import(“application.lib.PHPExcel.*”);

//引入PHPExcel相关文件
require_once "PHPExcel.php";
require_once 'PHPExcel/IOFactory.php';
require_once 'PHPExcel/Writer/Excel5.php';

//新建
$resultPHPExcel	= new PHPExcel();

//设置参数

//设值
$resultPHPExcel->getActiveSheet()->setCellValue('A1', '季度');
$resultPHPExcel->getActiveSheet()->setCellValue('B1', '名称');
$resultPHPExcel->getActiveSheet()->setCellValue('C1', '数量');
$i = 2;
foreach($data as $item){
	$resultPHPExcel->getActiveSheet()->setCellValue('A' . $i, $item['quarter']);
	$resultPHPExcel->getActiveSheet()->setCellValue('B' . $i, $item['name']);
	$resultPHPExcel->getActiveSheet()->setCellValue('C' . $i, $item['number']);
	$i ++;
}

//设置导出文件名
$outputFileName = 'total.xls';
$xlsWriter = new PHPExcel_Writer_Excel5($resultPHPExcel);
//ob_start();  ob_flush();

echo file_get_contents($finalFileName);  //file_get_contents() 函数把整个文件读入一个字符串中。和 file() 一样，不同的是 file_get_contents() 把文件读入一个字符串。
