Spreadsheet 支持excel 函数 公式使用

<?php
	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

<?php
	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

<?php
	$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;$a<$highestRow;$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'],
