PHP uses the pclzip class to implement file compression. Attached is the pclzip class download address.

The example in this article describes how PHP uses the pclzip class to achieve file compression. Share it with everyone for your reference, the details are as follows:

Use PclZIp (zip format) compression, you first need to download its package file (You can click hereDownload from this site). The function of PclZip is quite powerful. It can compress and decompress, as well as some methods of adding and deleting classes, etc. Of course, we can all find these contents online, so there is no need to remember them all. We just need to be able to quickly find how to use it online when we need to use it. First of all, what we need is to import the downloaded library file, such as

<?php include('pclzip/pclzip.lib.php'); ?>
//括号里面的地址改成自己的pclzip.lib.php 文件所在地址,
//它的所有的功能都在pclzip.lib.php里面

. After importing it, we can use it. Here is a simple method I wrote when using it.

<?php
$zipname = "test.zip"; //压缩包的名称
$zipnames = '/zipfiles/'.$zipname; //压缩包所在路径
$z = new PclZip($zipnames); //实例化这个PclZip类
$v_list = $z->create('file.txt,data/text.txt,folder'); //将文件进行压缩
if ($v_list == 0)
{
die("Error : ".$archive->errorInfo(true)); //如果有误，提示错误信息。
}
?>

This is a simple zip compression. In this method, we mainly use the PclZip class in PclZip and the method create in it to create a compressed package. From the above example, we can see the following content

<?php PclZip($zip_filename); ?>
//里面是该压缩包的名称以及所在路径。并不是把名称写上就可以了。
//如果路径不对是无法找到的。
<?php PclZip::create($filelist, [optional arguments]); ?>
//create方法来创建压缩包。
//$filelist可以用数组包含文件的名称和文件夹名称或者是一个字符串来包含.
//如果是多个文件的话可以用逗号来隔开，如上面的例子。
