A simple way to package folders into zip files in php

The example is as follows:

function addFileToZip($path,$zip){
  $handler=opendir($path); //打开当前文件夹由$path指定。
  while(($filename=readdir($handler))!==false){
    if($filename != "." && $filename != ".."){//文件夹文件名字为'.'和‘..'，不要对他们进行操作
      if(is_dir($path."/".$filename)){// 如果读取的某个对象是文件夹，则递归
        addFileToZip($path."/".$filename, $zip);
      }else{ //将文件加入zip对象
        $zip->addFile($path."/".$filename);
      }
    }
  }
  @closedir($path);
}
 
 
$zip=new ZipArchive();
if($zip->open('images.zip', ZipArchive::OVERWRITE)=== TRUE){
  addFileToZip('images/', $zip); //调用方法，对要打包的根目录进行操作，并将ZipArchive的对象传递给方法
  $zip->close(); //关闭处理的zip文件
}
