PHP实现生成Excel文件并导出的示例详解
于先生吖 人气:0在现在的项目里，不管是电商项目还是别的项目，在管理端都会有导出的功能，比方说订单表导出，用户表导出，业绩表导出。这些都需要提前生成excel表，然后在导出，实际上是在代码里生成一张excel表，然后通过下载api进行导出的。好了 先给大家讲一下示例
利用php导出excel我们大多会直接生成.xls文件，这种方便快捷。
首先我们先在项目中引入几个类
use \PhpOffice\PhpSpreadsheet\Spreadsheet; use \PhpOffice\PhpSpreadsheet\IOFactory; use \PhpOffice\PhpSpreadsheet\Cell\Coordinate; use PhpOffice\PhpSpreadsheet\Style\Border; use PhpOffice\PhpSpreadsheet\Style\Alignment;
然后我们在进行封装一个生成并导出excel表的方法，这里我们用订单表做示例
//订单信息导出excel
public function order_outputProjectExcel($info){
$newExcel = new Spreadsheet();//创建一个新的excel文档
$objSheet = $newExcel->getActiveSheet();//获取当前操作sheet的对象
$date = date('Ymd',time());
$name = '订单信息表';
$objSheet->setTitle($name);//设置当前sheet的标题
//样式设置 - 合并和拆分
$objSheet->mergeCells('A1:P1'); //合并单元格
//$sheet -> unmergeCells('C3:G3'); //拆分单元格
$objSheet->setCellValue('A1',$name);
//设置第一栏的中文标题
$objSheet->setCellValue('A2', '编号')
->setCellValue('B2', '商品图片')
->setCellValue('C2', '商品名称')
->setCellValue('D2', '会员编号')
->setCellValue('E2', '直属')
->setCellValue('F2', '非直属')
->setCellValue('G2', '订单号')
->setCellValue('H2', '商品单价')
->setCellValue('I2', '实付金额')
->setCellValue('J2', '商品佣金')
->setCellValue('K2', '会员佣金')
->setCellValue('L2', '直属佣金')
->setCellValue('M2', '非直属佣金')
->setCellValue('N2', '支付时间')
->setCellValue('O2', '支付渠道')
->setCellValue('P2', '订单状态');
//写入数据
$dataCount = count($info);
$k = 2;
if($dataCount == 0){
exit;
}else{
for ($i=0;$i<$dataCount;$i++){
$k = $k + 1;
$order=$i+1;
$objSheet->setCellValue('A' . $k, $info[$i]['id'])
->setCellValue('B' . $k, $info[$i]['goods_image'])
->setCellValue('C' . $k, $info[$i]['goods_name'])
->setCellValue('D' . $k, $info[$i]['user_num'])
->setCellValue('E' . $k, $info[$i]['user_upteam'])
->setCellValue('F' . $k, $info[$i]['user_un_upteam'])
->setCellValue('G' . $k, $info[$i]['order_id'])
->setCellValue('H' . $k, $info[$i]['goods_price'])
->setCellValue('I' . $k, $info[$i]['payment'])
->setCellValue('J' . $k, $info[$i]['goods_yongjin'])
->setCellValue('K' . $k, $info[$i]['user_yongjin'])
->setCellValue('L' . $k, $info[$i]['user_up_yongjin'])
->setCellValue('M' . $k, $info[$i]['user_un_upyongjin'])
->setCellValue('N' . $k, $info[$i]['paymenttime'])
->setCellValue('O' . $k, $info[$i]['pay_way_ch'])
->setCellValue('P' . $k, $info[$i]['status_ch']);
}
}
//设定样式
//所有sheet的表头样式 加粗
$font = [
'font' => [
'bold' => true,
'size' => 14,
],
];
$objSheet->getStyle('A1:P1')->applyFromArray($font);
//样式设置 - 水平、垂直居中
$styleArray = [
'alignment' => [
'horizontal' => Alignment::HORIZONTAL_CENTER,
'vertical' => Alignment::VERTICAL_CENTER
],
];
$objSheet->getStyle('A1:P2')->applyFromArray($styleArray);
//所有sheet的内容样式-加黑色边框
$borders = [
'borders' => [
'outline' => [
'borderStyle' => Border::BORDER_THIN,
'color' => ['argb' => '000000'],
],
'inside' => [
'borderStyle' => Border::BORDER_THIN,
]
],
];
$objSheet->getStyle('A1:P'.$k)->applyFromArray($borders);
//设置宽度
$cell = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P'];
foreach($cell as $k=>$v){
$objSheet->getColumnDimension($v)->setWidth(20);
// $objSheet->getColumnDimension($v)->setAutoSize(true);
}
$this->downloadExcel($newExcel,$name,'Xlsx');
}
//下载
private function downloadExcel($newExcel,$filename,$format)
{
ob_end_clean();
ob_start();
// $format只能为 Xlsx 或 Xls
if ($format == 'Xlsx') {
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
} elseif ($format == 'Xls') {
header('Content-Type: application/vnd.ms-excel');
}
// strtolower($format)
header("Content-Disposition: attachment;filename="
. $filename . '.' . strtolower($format));
header('Cache-Control: max-age=0');
$objWriter = IOFactory::createWriter($newExcel, $format);
$objWriter->save('php://output');
//通过php保存在本地的时候需要用到
// $objWriter->save($dir.'/demo.xlsx');
//以下为需要用到IE时候设置
// If you're serving to IE 9, then the following may be needed
//header('Cache-Control: max-age=1');
// If you're serving to IE over SSL, then the following may be needed
//header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
//header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); // always modified
//header('Cache-Control: cache, must-revalidate'); // HTTP/1.1
//header('Pragma: public'); // HTTP/1.0
exit;
}
到这一步其实就已经成功了95%了。剩下的5%只需要你调用上面的方法传入正确的参数即可
model('Apimodel')->order_outputProjectExcel($info);
这里的$info是你的订单详情。必须要做时间筛选，如果不做时间筛选的话 数据量一多，你的系统会崩的。
这里的for循环就是你传入的 $info。 如果说你的 $info 是空的 那么导出的excel打开的时候还会出现
for ($i=0;$i<$dataCount;$i++){
$k = $k + 1;
$order=$i+1;
$objSheet->setCellValue('A' . $k, $info[$i]['id'])
->setCellValue('B' . $k, $info[$i]['goods_image'])
->setCellValue('C' . $k, $info[$i]['goods_name'])
->setCellValue('D' . $k, $info[$i]['user_num'])
->setCellValue('E' . $k, $info[$i]['user_upteam'])
->setCellValue('F' . $k, $info[$i]['user_un_upteam'])
->setCellValue('G' . $k, $info[$i]['order_id'])
->setCellValue('H' . $k, $info[$i]['goods_price'])
->setCellValue('I' . $k, $info[$i]['payment'])
->setCellValue('J' . $k, $info[$i]['goods_yongjin'])
->setCellValue('K' . $k, $info[$i]['user_yongjin'])
->setCellValue('L' . $k, $info[$i]['user_up_yongjin'])
->setCellValue('M' . $k, $info[$i]['user_un_upyongjin'])
->setCellValue('N' . $k, $info[$i]['paymenttime'])
->setCellValue('O' . $k, $info[$i]['pay_way_ch'])
->setCellValue('P' . $k, $info[$i]['status_ch']);
}
最后就是这样的效果
