使用PHPExcel导出数据到Excel的方法

● PHP版本5.6.38

● mysql版本5.0

//连接数据库$mysql_server_name = "*.*.*.*";$mysql_username="user";$mysql_password="dbpasswd";$mysql_database="test";$conn = mysqli_connect($mysql_server_name,$mysql_username,$mysql_password,$mysql_database);// 检测连接if ($conn->connect_error) {    die("连接失败: " . $conn->connect_error);}//设置字符集，如果不设置的话中文可能会乱码$conn->query("set names utf8");//查询数据$sql = "SELECT * FROM testdata WHERE  inserttime > '2019-09-13' AND inserttime <'2019-0916'";$result = $conn->query($sql);//遍历将数据放入数组中$data =array();while ($row = $result->fetch_assoc()){    $data[] = $row;}//将查询出来的数据导入Excel中require_once('./PHPExcel/PHPExcel.php');// 创建Excel文件对象$objPHPExcel = new PHPExcel();// 设置文档信息，这个文档信息windows系统可以右键文件属性查看$objPHPExcel->getProperties()->setCreator("wnn")    ->setLastModifiedBy("wnn")    ->setTitle("原创文章链接");$objPHPExcel->setActiveSheetIndex(0)    ->setCellValue('A1','文章ID')    ->setCellValue('B1','标题')    ->setCellValue('C1','链接')    ->setCellValue('D1','作者')    ->setCellValue('E1','发布时间');//设置excel表单根据内容大小变化$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setAutoSize(true);$objPHPExcel->getActiveSheet()->getColumnDimension('B')->setAutoSize(true);$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setAutoSize(true);$objPHPExcel->getActiveSheet()->getColumnDimension('D')->setAutoSize(true);$objPHPExcel->getActiveSheet()->getColumnDimension('E')->setAutoSize(true);//$i=1是标题行$i=2;foreach ($data as $k=>$v){    $objPHPExcel->setActiveSheetIndex(0)        ->setCellValue('A'.$i,$v['id'])        ->setCellValue('B'.$i,$v['title'])        ->setCellValue('C'.$i,$v['arcurl'])        ->setCellValue('D'.$i,$v['writer'])        ->setCellValue('E'.$i,$v['senddate']);　　　//给C列的文字加上链接    $objPHPExcel->getActiveSheet()->getCell('C'.$i)->getHyperlink()->setUrl($v['arcurl']);    $i++;}//给C列的超链接字体颜色变成蓝色$length = count($data)+1;$objPHPExcel->getActiveSheet()->getStyle( 'C2:C'.$length)->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_BLUE);//文件名称$filename=urlencode('原创作品').'_'.date('YmdHis');//生成xls文件ob_end_clean();//清除缓冲区,避免乱码header('Content-Type: application/vnd.ms-excel');header('Content-Disposition: attachment;filename="'.$filename.'.xls"');header('Cache-Control: max-age=0');$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');$objWriter->save('php://output');

如果导出来的Excel文字都是乱码的话，一定要在header()前面加上ob_end_clean()！
