[PHP知识库]解决php使用ZipArchive解压时中文乱码问题（纯php，绕开ZipArchive）

使用php自带的ZipArchive来解压带中文文件名压缩包时会造成乱码，现象如下：

网上查阅基本上给出的答案大同小异，自己照着同样的方法试了都不能解决，下图是网上给出的方案：

经过摸索终于找到了解决方案，那就是弃用ZipArchive，选择其他的途径，经过比较我选择了“PhpZip”，优点是：纯php（不需要扩展和类），下面介绍安装方法：

composer安装：

composer require nelexa/zip
如果选择版本的话：composer require nelexa/zip:^3.0 (3.0版本号)

使用方法：

//解压文件
$fileAddess = "压缩包地址";
$toDir = "解压目录";
$zipFile = new \PhpZip\ZipFile();
$zipFile->openFile($fileAddess) // open archive from file
->extractTo($toDir); // extract files to the specified directory
$zipFile->close();

注释：（**如果安装好使用正常请忽略下面的注释内容**）
1.我的压缩包放在共享盘里面连接的是smb地址，可能会出现报错："Destination is not writable directory"，这个坑已经踩过：打开ZipFile.php这个文件，找到“extractTo”方法，将“is_writable”函数改掉，或者去掉，然后再转换一下编码格式！，下面有注释的是我修改的内容！

/**
