Spreadsheet 支持excel 函数 公式使用

namespace app

# 给类文件的命名空间起个别名

use PhpOffice\PhpSpreadsheet\Spreadsheet;

# Xlsx类 将电子表格保存到文件

use PhpOffice\PhpSpreadsheet\Writer\Xlsx;

# 实例化 Spreadsheet 对象

$spreadsheet = new Spreadsheet();

# 获取活动工作薄

$sheet = $spreadsheet->getActiveSheet();

$sheet->setCellValue('A1','10');

$sheet->setCellValue('B1','15');

$sheet->setCellValue('C1','20');

$sheet->setCellValue('D1','25');

$sheet->setCellValue('E1','30');

$sheet->setCellValue('G1','35');

$sheet->setCellValue('A2', '总数：');

$sheet->setCellValue('B2', '=SUM(A1:G1)');

$sheet->setCellValue('A3', '平均数：');

$sheet->setCellValue('B3', '=AVERAGE(A1:G1)');

$sheet->setCellValue('A4', '最小数：');

$sheet->setCellValue('B4', '=MIN(A1:G1)');

$sheet->setCellValue('A5', '最大数：');

$sheet->setCellValue('B5', '=MAX(A1:G1)');

$sheet->setCellValue('A6', '最大数：');

$sheet->setCellValue('B6', '\=MAX(A1:G1)');// 使用转义字符

// 批量赋值

$sheet->setCellValue('A1','ID');

$sheet->setCellValue('B1','姓名');

$sheet->setCellValue('C1','年龄');

$sheet->setCellValue('D1','身高');

$sheet->fromArray(

[

[1,'欧阳克','18岁','188cm'],

[2,'黄蓉','17岁','165cm'],

[3,'郭靖','21岁','180cm']

],

3,

'A2'

);

// 合并单元格 合并后，赋值只能给A1，开始的坐标。

$sheet->mergeCells('A1:B5');

$sheet->getCell('A1')->setValue('欧阳克');

# Xlsx类 将电子表格保存到文件

$writer = new Xlsx($spreadsheet);

$writer->save('1.xlsx');

// 客户端文件下载

header('Content-Type:application/vnd.ms-excel');

header('Content-Disposition:attachment;filename=1.xls');

header('Cache-Control:max-age=0');

$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xls');

$writer->save('php://output');

读取表格文件

namespace app;

# 创建读操作

$reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader('Xlsx');

# 打开文件、载入excel表格

$spreadsheet = $reader->load('1.xlsx');

# 获取活动工作薄

$sheet = $spreadsheet->getActiveSheet();

# 获取 单元格值 和 坐标

$cellC1 = $sheet->getCell('B2');

echo '值: ', $cellC1->getValue(),PHP_EOL;

echo '坐标: ', $cellC1->getCoordinate(),PHP_EOL;

$sheet->setCellValue('B2','欧阳锋');

# 获取 单元格值 和 坐标

$cellC2 = $sheet->getCell('B2');

echo '值: ', $cellC2->getValue(),PHP_EOL;

echo '坐标: ', $cellC2->getCoordinate();

导入功能

$file = $_FILES['file']['tmp_name'];

# 载入composer自动加载文件

require 'vendor/autoload.php';

# 载入方法库

require 'function.php';

# 创建读操作

$reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader('Xlsx');

# 打开文件、载入excel表格

$spreadsheet = $reader->load($file);

# 获取活动工作薄

$sheet = $spreadsheet->getActiveSheet();

# 获取总列数

$highestColumn = $sheet->getHighestColumn();

# 获取总行数

$highestRow = $sheet->getHighestRow();

# 列数 改为数字显示

$highestColumnIndex = \PhpOffice\PhpSpreadsheet\Cell\Coordinate::columnIndexFromString($highestColumn);

$log = [];

for($a=2;$a

$title = $sheet->getCellByColumnAndRow(1,$a)->getValue();

$cat_fname = $sheet->getCellByColumnAndRow(2,$a)->getValue();

$cat_name = $sheet->getCellByColumnAndRow(3,$a)->getValue();

$price = $sheet->getCellByColumnAndRow(4,$a)->getValue();

$img = $sheet->getCellByColumnAndRow(5,$a)->getValue();

$cat_fid = find('shop_cat','id','name="'.$cat_fname.'"');

$cat_id = find('shop_cat','id','name="'.$cat_name.'"');

$data = [

'title' => $title,

'cat_fid' => $cat_fid['id'],

'cat_id' => $cat_id['id'],

'price' => $price,

'img' => $img,

'add_time' => time(),

];

$ins = insert('shop_list',$data);

if($ins){

$log[] = '第'.$a.'条，插入成功';

}else{

}

}

echo json_encode(['code'=>0,'msg'=>'成功','data'=>$log]);
