php压缩与归档扩展-zip基本用法

简介

此扩展可以让你透明地读写ZIP压缩文档以及它们里面的文件。

安装

1. 编译安装

   编译 PHP 时用 --enable-zip 配置选项来提供 zip 支持。
   

2. 下载安装包安装

   # libzip 依赖，php7.4版本中要求 libzip >=0.11
   wget https://nih.at/libzip/libzip-1.2.0.tar.gz 
   tar -zxvf libzip-1.2.0.tar.gz 
   cd libzip-1.2.0 
   sudo ./configure 
   sudo make
   sudo make install
   

   php原包中安装

   cd php-7.4.4/ext/zip
   /usr/local/php/bin/phpize
   ./configure --with-php-config=/usr/local/php/bin/php-config
   make
   make install
   

   zip pecl官网

   # 安装zip包
   wget https://pecl.php.net/get/zip-1.15.5.tgz
   tar -zxvf zip-1.15.5.tgz
   cd zip-1.15.5/
   phpize
   ./configure --with-php-config=/usr/local/php/bin/php-config
   make
   make install
   

   将zip加入php.ini

   sudo vim /etc/php5/fpm/conf.d/zip.ini
   

   [zip]
   extension=zip.so
   

   重启php

编码

1. 多个单个文件打包

   # 打包临时文件夹，请设置可写
   $tmp_dir = "/tmp/zip_dir";
   # 打包zip的文件名
   $zip_file_name = "zip_file_" . time();
   # zip的绝对路径
   $zip_file = $tmp_dir . "/" . $zip_file_name . ".zip";
   # 开始打包
   $zip = new ZipArchive();
   $res = $zip->open($zip_file, ZipArchive::CREATE | ZipArchive::OVERWRITE);
   if($res === true) {
        $zip_file_arr = array(
            'a.txt' => "/tmp/file_list/a.txt",
            'b.txt' => "/tmp/file_list/b.txt",
        );
        # $key = 文件名
        # $value = 文件路径
        foreach ($zip_file_arr as $key => $value) {
            $zip->addFile($value, $key);
        }
        # 关闭写
        $zip->close();
   }else{
        exit("zip open fail! code: " . $res);
   }
   

2. 文件夹打包

   # 打包临时文件夹，请设置可写
   $tmp_dir = "/tmp/zip_dir";
   # 打包的文件夹及文件夹下的文件
   $path = "/tmp/file_list";
   # zip的绝对路径
   $zip_file = $tmp_dir . "/" . $zip_file_name . ".zip";
   # 开始打包
   $zip = new ZipArchive();
   $res = $zip->open($zip_file, ZipArchive::CREATE | ZipArchive::OVERWRITE);
   if($res === true) {
    $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::LEAVES_ONLY);
        foreach ($files as $name => $file) {
            // Skip directories (they would be added automatically)
            if (!$file->isDir()) {
                // Get real and relative path for current file
                $filePath = $file->getRealPath();
                $relativePath = substr($filePath, strlen($path) + 1);
                // Add current file to archive
                $zip->addFile($filePath, $relativePath);
            }
        }
        # 关闭写
        $zip->close();
   }else{
        exit("zip open fail! code: " . $res);
   }
   

3. 如果要提交http下载的话，可使用如下代码

   # http下载
   $fp_zip = fopen('php://output', 'a');
   header("Content-type:application/octet-stream");
   header("Content-Disposition:attachment;filename=" . $zip_file_name . ".zip");
   header("Accept-ranges:bytes");
   fwrite($fp_zip, file_get_contents($zip_file));
   fclose($fp_zip);
   // 删除zip文件
   unlink($zip_file);
