一、`PhpSpreadsheet` 介绍

1、`PhpSpreadsheet` 是什么

[info] 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

格式	读	写
Open Document Format/OASIS (.ods)	✓	✓
Office Open XML (.xlsx) Excel 2007 and above	✓	✓
BIFF 8 (.xls) Excel 97 and above	✓	✓
BIFF 5 (.xls) Excel 95	✓
SpreadsheetML (.xml) Excel 2003	✓
Gnumeric	✓
HTML	✓	✓
SYLK	✓
CSV	✓	✓
PDF		✓

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

<?php

    # 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

	# 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');

	$sheet = $spreadsheet->getActiveSheet();

	$sheet->setCellValue('A1','ID');
	$sheet->setCellValue('B1','姓名');
	$sheet->setCellValue('C1','年龄');
	$sheet->setCellValue('D1','身高');

	$sheet->fromArray(

	# Xlsx类 将电子表格保存到文件
	use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
	$writer = new Xlsx($spreadsheet);
	$writer->save('1.xlsx');

[info] 注：合并后，赋值只能给A1，开始的坐标。

4、拆分单元格

<?php
	# 载入composer自动加载文件

	$sheet->setCellValueByColumnAndRow(3, 2, '18岁');
	$sheet->setCellValueByColumnAndRow(4, 2, '188cm');

	// MIME 协议，文件的类型，不设置，会默认html
	header('Content-Type:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
	// MIME 协议的扩展
	header('Content-Disposition:attachment;filename=1.xlsx');
	// 缓存控制
	header('Cache-Control:max-age=0');

	$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');
	// php://output 它是一个只写数据流, 允许你以 print 和 echo一样的方式写入到输出缓冲区。 
	$writer->save('php://output');

2、xls 文件下载

<?php
	# 载入composer自动加载文件

	$sheet->setCellValueByColumnAndRow(3, 2, '18岁');
	$sheet->setCellValueByColumnAndRow(4, 2, '188cm');

	$sheet->setTitle('欧阳克');

	// MIME 协议，文件的类型，不设置，会默认html
	header('Content-Type:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
	// MIME 协议的扩展
	header('Content-Disposition:attachment;filename=1.xlsx');
	// 缓存控制
	header('Cache-Control:max-age=0');

	$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet, 'Xlsx');
	// php://output 它是一个只写数据流, 允许你以 print 和 echo一样的方式写入到输出缓冲区。 
	$writer->save('php://output');

4、读取表格

<?php
	# 载入composer自动加载文件
	require 'vendor/autoload.php';

	# 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;
