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()！
