How PHP uses the pclzip class to implement file compression (with the pclzip class download address),
The example in this article describes how PHP uses the pclzip class to implement file compression. Share it with everyone for your reference, the details are as follows:
To 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'); ?>
//括號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 introduction, we can use it. Here is a simple method I wrote when using it.
<?php
$zipname = "test.zip"; //壓縮包的名稱
$zipnames = '/zipfiles/'.$zipname; //壓縮包所在路徑
$z = new PclZip($zipnames); //實(shí)例化這個PclZip類
$v_list = $z->create('file.txt,data/text.txt,folder'); //將文件進(jìn)行壓縮
if ($v_list == 0)
{
die("Error : ".$archive->errorInfo(true)); //如果有誤，提示錯誤信息。
}
?>
This is a simple zip compression. In this method, we mainly use the PclZip class in PclZip and the method create in it to create a compressed package. From the above example we can see the following content
<?php PclZip($zip_filename); ?> //里面是該壓縮包的名稱以及所在路徑。并不是把名稱寫上就可以了。 //如果路徑不對是無法找到的。 <?php PclZip::create($filelist, [optional arguments]); ?> //create方法來創(chuàng)建壓縮包。 //$filelist可以用數(shù)組包含文件的名稱和文件夾名稱或者是一個字符串來包含. //如果是多個文件的話可以用逗號來隔開，如上面的例子。

How do I embed PHP code in an HTML file?
Jun 22, 2025 am 01:00 AM
You can embed PHP code into HTML files, but make sure that the file has an extension of .php so that the server can parse it correctly. Use standard tags to wrap PHP code, insert dynamic content anywhere in HTML. In addition, you can switch PHP and HTML multiple times in the same file to realize dynamic functions such as conditional rendering. Be sure to pay attention to the server configuration and syntax correctness to avoid problems caused by short labels, quotation mark errors or omitted end labels.
What are the best practices for writing clean and maintainable PHP code?
Jun 24, 2025 am 12:53 AM
The key to writing clean and easy-to-maintain PHP code lies in clear naming, following standards, reasonable structure, making good use of comments and testability. 1. Use clear variables, functions and class names, such as $userData and calculateTotalPrice(); 2. Follow the PSR-12 standard unified code style; 3. Split the code structure according to responsibilities, and organize it using MVC or Laravel-style catalogs; 4. Avoid noodles-style code and split the logic into small functions with a single responsibility; 5. Add comments at key points and write interface documents to clarify parameters, return values ??and exceptions; 6. Improve testability, adopt dependency injection, reduce global state and static methods. These practices improve code quality, collaboration efficiency and post-maintenance ease.
