Hyperf & PhpSpreadsheet介绍

Hyperf 介绍

Hyperf 是基于 ​​Swoole 4.5+​​​ 实现的高性能、高灵活性的 PHP 协程框架，内置协程服务器及大量常用的组件，性能较传统基于 ​​PHP-FPM​​​ 的框架有质的提升，提供超高性能的同时，也保持着极其灵活的可扩展性，标准组件均基于 ​​PSR 标准​​​ 实现，基于强大的依赖注入设计，保证了绝大部分组件或类都是 ​​可替换​​​ 与 ​​可复用​​ 的。

PhpOffice/PhpSpreadsheet 介绍

PhpSpreadsheet是一个用纯PHP编写的库，它提供了一组类，允许您读取和写入各种电子表格文件格式，如Excel和LibreOffice Calc。

PhpSpreadsheet是PHPExcel的下一个版本。它破坏了兼容性，从而大大提高了代码库质量（命名空间、PSR 合规性、使用最新的 PHP 语言功能等）。

因为所有的努力都转移到了PhpSpreadsheet上，PHPExcel将不再被维护。所有对 PHPExcel 的贡献、补丁和新功能都应针对 PhpSpreadsheet 分支。​​master​​

• GitHub ​​PHPOffice/PhpSpreadsheet：用于读取和写入电子表格文件的纯PHP库 (github.com)​​
• 官方使用文档  ​​Welcome to PhpSpreadsheet’s documentation – PhpSpreadsheet Documentation​​
• api文档 ​​Documentation (phpoffice.github.io)​​

PhpOffice/PhpSpreadsheet 安装

使用​​composer​​将 PhpSpreadsheet 安装到你的项目中：

1.composer require phpoffice/phpspreadsheet

或者，如果您计划使用它们，还可以下载文档和示例：

1.composer require phpoffice/phpspreadsheet --prefer-source

文件导出导入&代码实例

csv文件导出

导出实例类文件

函数说明：使用hyperf框架的跨域中间件

• ​​->withHeader​​ 添加浏览器响应头
• ​​->withBody​​ 添加浏览器内容主体
• ​​Headers​​ 可以根据实际情况进行改写。

代码实例：

<?php
/**
 * Created by PhpStorm.
 * Created by OwenZhang at 2021/11/8 14:39
 */

namespace AppCommon;

use HyperfHttpMessageStreamSwooleStream;
use HyperfHttpServerResponse;

class Csv
{
    /**
    $head = ['name'=>'名字','score'=>'得分'];
    $data = [
                ['name' => '张三', 'score' => '80'],
                ['name' => '李四', 'score' => '90'],
                ['name' => '王五', 'score' => '60'],
            ];
     $fileName = '测试'
     */
    /**
     * Describe:   导数数据 （csv 格式）
     * @param array $head
     * @param array $body
     * @param string $fileName '测试.csv','测试.xlsx'
     * @return PsrHttpMessageResponseInterface
     * Created by owenzhang at 2021/11/8 14:47
     */
    static function export(array $head, array $body, string $fileName)
    {
        $head_keys = array_keys($head);
        $head_values = array_values($head);
        $fileData = self::utfToGbk(implode(',', $head_values)) . "n";

        foreach ($body as $value) {
            $temp_arr = [];
            foreach ($head_keys as $key) {
                $temp_arr[] = $value[$key] ?? '';
            }
            $fileData .= self::utfToGbk(implode(',', $temp_arr)) . "n";
        }
        $response = new Response();
        $contentType = 'text/csv';
        return $response->withHeader('content-description', 'File Transfer')
            ->withHeader('content-type', $contentType)
            ->withHeader('content-disposition', "attachment; filename={$fileName}")
            ->withHeader('content-transfer-encoding', 'binary')
            ->withHeader('pragma', 'public')
            ->withBody(new SwooleStream($fileData));
    }

    /**
     * 字符转换（utf-8 => GBK）
     * @param $data
     * @return false|string
     */
    static function utfToGbk($data)
    {
        return mb_convert_encoding($data,"GBK","UTF-8");
       # return iconv('utf-8', 'GBK', $data);
    }

}

调用导出实例函数方法

调用上面的csv文件导出类，浏览器调整新页面直接下载导出。

代码实例：

<?php
/**
 * Describe: 列表导出
 * Route: get /admin/badword_list_export
 * Created by OwenZhang at 2021/12/13 10:14
 */
public function getBadwordListExport(): ResponseInterface
{
    $page = (int)$this->request->input('page', 1);
    $pageSize = (int)$this->request->input('page_size', 15);
    $word = (string)$this->request->input('word', '');
    $type = (string)$this->request->input('type', '');

    $container = ApplicationContext::getContainer();
    $exportArray = $container->get(BadwordServiceInterface::class)->getBadwordListExport($page, $pageSize, $word, $type);
    //$exportArray 数组，每个里面键值和$header一样   
    
    set_time_limit(0);
    ini_set('memory_limit', '5048M');
    $filename = '敏感词数据' . date('ymdHis');

    $header = [
        'badword_id' => '敏感词id',
        'word' => '敏感词',
        'type' => '分类',
        'style_name' => '应用区域',
        'replace_word' => '替换词',
    ];

    return Csv::export($header, $exportArray, $filename);
}

excel文件导出

导出实例类文件

1. xls后缀excel文件导出的heard头：
   ​​​xls='application/vnd.ms-excel'​​
2. xlsx后缀excel文件导出的heard头：
   ​​​xlsx='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'​​

函数说明：

• 构造函数 创建一个PhpSpreadsheet实例 ​​__construct（）​​
• 设置表头 ​​$title=['id','标题','内容'] setHeader($title)​​
• 添加表内容​​$data=[ [1,标题1，内容1], [2,标题2，内容2], ... ] addData($data)​​
• 保存到服务器本地 ​​$fileName=文件名 saveToLocal($fileName)​​
• 直接从浏览器下载到本地，有问题，不使用，​​php://output​​​ 目前PhpSpreadsheet插件有问题，PhpSpreadsheet插件作者还在修复 ​​saveToBrowser($fileName)​​
• 保存临时文件在从浏览器自动下载到本地 ​​saveToBrowserByTmp($fileName)​​

代码实例：

<?php
/**
 * Created by PhpStorm.
 * Created by OwenZhang at 2021/12/28 14:39

            }
            $this->row++;
        }
        return $this;

    //保存到服务器本地

excle文件导入（批量添加数据到Mysql）

调用PhpSpreadsheet读取函数方法

函数说明：

• 获取上传文件的临时路径 ​​$file['tmp_file']​​
• 指定第一个工作表为当前 ​​$spreadsheet->getSheet(0)->toArray();​​
• execl文件读取数据​​$container->get(BadwordServiceInterface::class)->getBadwordListImport($data);​​
• 批量添加数据到mysql ​​getBadwordListImportToMysql​​

        if ($key != 0) {
            $insertData[] = [
                'badword_id' => $badwordId + $key + 1,
                'word' => $datum[1],
                'type' => $datum[2],
                'style' => 1,
                'replace_word' => '',
