The example in this article describes the use of ZipArchive method for packaging compressed files in PHP. Share it with everyone for your reference, the details are as follows:

I mentioned the PclZip method of php packaging and compressing files. Today I will talk about another simpler method, using ZipArchive to compress files. This is an extension class of php. This extension has been supported since php5.2 version. If you get an error when using it, check whether the semicolon in front of extension=php_zip.dll in php.ini has been removed, and then try again. Restart Apache to use this class library.

It is very simple to use ZipArchive to compress files. The official php website has provided me with many related examples. You can take a look at http://www.php.net/manual/zh/class.ziparchive.php, for example:

<&#63;php
$zip = new ZipArchive; //首先实例化这个类
if ($zip->open('test.zip') === TRUE) { //然后查看是否存在test.zip这个压缩包
  $zip->addFile('too.php');
  $zip->addFile('test.php'); //将too.php和test.php两个文件添加到test.zip压缩包中
  $zip->close(); //关闭
  echo 'ok';
} else {
  echo 'failed';
}
?>

The following are some parameter descriptions:

<&#63;php
/******** ziparchive 可选参数 *******/
/*
1.ZipArchive::addEmptyDir
添加一个新的文件目录
2.ZipArchive::addFile 
将文件添加到指定zip压缩包中。
3.ZipArchive::addFromString 
添加的文件同时将内容添加进去
4.ZipArchive::close 
关闭ziparchive
5.ZipArchive::extractTo 
将压缩包解压
6.ZipArchive::open
打开一个zip压缩包
7.ZipArchive::getStatusString
返回压缩时的状态内容,包括错误信息,压缩信息等等
8.ZipArchive::deleteIndex
删除压缩包中的某一个文件,如:deleteIndex(0)删除第一个文件
9.ZipArchive::deleteName
删除压缩包中的某一个文件名称,同时也将文件删除。
......

In short, as long as your php5.2 version or above is used, it is more convenient to use ZipArchive for file compression. Specifically, which one runs faster than PclZip? This Lezi has not been tested yet. If you are interested, you can play around with it.
