PHP教程：使用PhpSpreadsheet操作读写Excel实例

这当中涉及到一些表格的相关操作。首先想到使用 PhpSpreadsheet

1、PhpSpreadsheet 是什么
PhpSpreadsheet是一个用纯PHP编写的库，提供了一组类，使您可以读取和写入不同的电子表格文件格式
PhpSpreadsheet提供了丰富的API接口，可以设置诸多单元格以及文档属性，包括样式、图片、日期、函数等等诸多应用，总之你想要什么样的Excel表格，PhpSpreadsheet都能做到

使用 PhpSpreadsheet 开发的PHP要求 7.1或更高版本
PhpSpreadsheet 支持链式操作
2、PhpSpreadsheet 支持的文件格式
在这里插入图片描述

3、PhpSpreadsheet 官方网址
https://phpspreadsheet.readthedocs.io
4、PhpSpreadsheet 安装
composer require phpoffice/phpspreadsheet
二、基础知识
1、载入

<?php
# 载入composer自动加载文件 require 瑞块儿
require 'vendor/autoload.php'; autoload 奥特老特
# 给类文件的命名空间起个别名
use PhpOffice\PhpSpreadsheet\Spreadsheet;
# 实例化 Spreadsheet 对象
$spreadsheet = new Spreadsheet();

2、获取工作簿
getActiveSheet

<?php
# 载入composer自动加载文件
require 'vendor/autoload.php';
# 给类文件的命名空间起个别名
use PhpOffice\PhpSpreadsheet\Spreadsheet;
# 实例化 Spreadsheet 对象
$spreadsheet = new Spreadsheet();
# 获取活动工作薄
$sheet = $spreadsheet->getActiveSheet();

3、获取单元格
两种获取单元格方式
getCell
getCellByColumnAndRow

use PhpOffice\PhpSpreadsheet\Spreadsheet;
# 实例化 Spreadsheet 对象
$spreadsheet = new Spreadsheet();
# 获取活动工作薄
$sheet = $spreadsheet->getActiveSheet();
# 获取单元格
$cell = $sheet->getCell('A1');
$cell = $sheet->getCellByColumnAndRow(1,1);

4、设置单元格
setValue
参数：单元格的值

<?php
# 载入composer自动加载文件
require 'vendor/autoload.php';
# 给类文件的命名空间起个别名
use PhpOffice\PhpSpreadsheet\Spreadsheet;
# 实例化 Spreadsheet 对象
$spreadsheet = new Spreadsheet();

# 获取单元格
$cellA = $sheet->getCell('A1');
# 设置单元格值
$cellA->setValue('欧阳克');

# 获取单元格
$cellB = $sheet->getCellByColumnAndRow(1,2);
# 设置单元格值
$cellB->setValue('黄蓉');

# 获取设置单元格，链式操作
$sheet->getCell('A3')->setValue('郭靖');
$sheet->getCellByColumnAndRow(1,4)->setValue('杨康');

5、获取单元格值
getValue 获取单元格值
getCoordinate 获取单元格坐标
