PHP实现生成Excel文件并导出的示例详解
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
