The example in this article describes how to decompress a ZIP file to a specified folder with PHP. Share it with everyone for your reference, the details are as follows:
/** * function: 解压zip 格式的文件 * author:friker * date:2015-15-14 * reference:http://php.cn/manual/zh/ref.zip.php * all rights reserved:php.cn */ class Unzip{ public function __construct(){ //init code here... header("content-type:text/html;charset=utf8"); } /** * 解压文件到指定目录 * * @param string zip压缩文件的路径 * @param string 解压文件的目的路径 * @param boolean 是否以压缩文件的名字创建目标文件夹 * @param boolean 是否重写已经存在的文件 * * @return boolean 返回成功 或失败 */ public function unzip($src_file, $dest_dir=false, $create_zip_name_dir=true, $overwrite=true){ if ($zip = zip_open($src_file)){ if ($zip){ $splitter = ($create_zip_name_dir === true) ? "." : "/"; if($dest_dir === false){ $dest_dir = substr($src_file, 0, strrpos($src_file, $splitter))."/"; } // 如果不存在 创建目标解压目录 $this->create_dirs($dest_dir); // 对每个文件进行解压 while ($zip_entry = zip_read($zip)){ // 文件不在根目录 $pos_last_slash = strrpos(zip_entry_name($zip_entry), "/"); if ($pos_last_slash !== false){ // 创建目录 在末尾带 / $this->create_dirs($dest_dir.substr(zip_entry_name($zip_entry), 0, $pos_last_slash+1)); } // 打开包 if (zip_entry_open($zip,$zip_entry,"r")){ // 文件名保存在磁盘上 $file_name = $dest_dir.zip_entry_name($zip_entry); // 检查文件是否需要重写 if ($overwrite === true || $overwrite === false && !is_file($file_name)){ // 读取压缩文件的内容 $fstream = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry)); @file_put_contents($file_name, $fstream); // 设置权限 chmod($file_name, 0777); echo "save: ".$file_name."<br />"; } // 关闭入口 zip_entry_close($zip_entry); } } // 关闭压缩包 zip_close($zip); } }else{ return false; } return true; } /** * 创建目录 */ public function create_dirs($path){ if (!is_dir($path)){ $directory_path = ""; $directories = explode("/",$path); array_pop($directories); foreach($directories as $directory){ $directory_path .= $directory."/"; if (!is_dir($directory_path)){ mkdir($directory_path); chmod($directory_path, 0777); } } } } } /* using: $z = new Unzip(); $z->unzip("./bootstrap-3.3.4.zip",'./unzipres/', true, false); */

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

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),
