PHP implements online decompression of zip compressed files
The example in this article describes how to decompress ZIP files online with php. Share it with everyone for your reference. The specific analysis is as follows:
In the PHP function library, I only found a ZLIB function that has something to do with compression. But what disappointed me was that it failed to decode ZIP files, but in the end I found a solution. This function is implemented through the program execution function of PHP, because there are so many things that can decode ZIP files. If you don’t believe it, you can look for it where you can download the software. I guarantee you will not be disappointed. My word You can’t be wrong.
The following is the original file of the program. The upload.php code is as follows:
<table border="0" > <form ENCTYPE="multipart/form-data" action="upsave.php" method="post"> <tr> <td>如果是*.ZIP的文件会被自动解压缩 <INPUT NAME="MyFile" TYPE="File" size="50"> </td> </tr> <tr> <td colspan="2" align="center"> <input type="Submit" value=" 上传 " class=iwhite> <input type="reset" value=" 重填 " class=iwhite> </td> </tr> </table> </body> </html>
upsave.php code is as follows:
<?php //保存上传的文件 $filename="$MyFile_name"; copy($MyFile,"$filename"); unlink($MyFile); //判断是否是ZIP文件 $expand_name=explode(".",$filename); if($expand_name[1] == "zip" or $expand_name[1] == "ZIP") { $str="pkunzip.exe -e $filename "; exec($str); unlink($filename); } ?>
I have tested the above program, as long as it is placed on the server, it will be fine. However, the directory must have write permissions, and a pkunzip.exe file must also be placed in the directory.
I hope this article will be helpful to everyone’s PHP programming design.

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
