PhpSpreadsheet是一个用纯PHP编写的库，提供了一组类，可以方便我们进行读取和写入不同的电子表格文件格式，因此PHP使用PhpSpreadsheet能很比较方便的对Excel进行操作，有些朋友可以能没有接触过PhpSpreadsheet，下面小编就给大家介绍一下PHP使用PhpSpreadsheet操作Excel的方法。

一、PhpSpreadsheet 介绍

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

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

七、实战

1、导出数据

login_log 登陆日志表

CREATE TABLE `login_log` (
	`id` int(11) NOT NULL AUTO_INCREMENT,
	`uid` int(11) DEFAULT NULL COMMENT '管理员ID',
	`client` tinyint(4) unsigned DEFAULT '0' COMMENT '0-PC 1-ios 2-android',
	`add_time` int(11) DEFAULT '0' COMMENT '创建时间',
	`ip` bigint(20) unsigned NOT NULL DEFAULT '0' COMMENT '登录IP',
	PRIMARY KEY (`id`) USING BTREE
) ENGINE=MyISAM AUTO_INCREMENT=1122 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci COMMENT='登录日志';

index.php 数据列表页面

<?php 
	# 载入方法库
	require 'function.php';

	$select = select('login_log','*');

	if(empty($select)){
		exit;
	}else{
		foreach($select as &$v){
			switch ($v['client']) {
				case 0:
					$v['client'] = 'PC电脑';
					break;
				case 1:
					$v['client'] = '苹果手机';
					break;
				case 2:
					$v['client'] = '安卓手机';
					break;
			}
			$v['add_time'] = date('Y-m-d H:i:s',$v['add_time']);
		}
	}
?>
