QPM全名是 Quick Process Management Framework for PHP. PHP 是强大的web开发语言,以至于大家常常忘记PHP 可以用来开发健壮的命令行(CLI)程序以至于daemon程序。 而编写daemon程序免不了与各种进程管理打交道。QPM正式为简化进程管理而开发的类库。QPM的项目地址是: https://github.com/Comos/qpm
环境要求- *nix系统。由于QPM的核心功能是基于pcntl扩展的,无法用于windows系统。
- PHP 5.4.x及以上版本,并且开启pcntl, posix。
使用 Composer 安装QPM(推荐)
1) 安装Composer
Composer 是PHP用来管理软件包依赖关系的工具。使用Composer可以非常便利的实现依赖包的快速下载和安装。
使用以下命令,可以快速安装Composer:
curl -sS https://getcomposer.org/installer | phpmv composer.phar /usr/local/bin/composer
也可参考:Composer安装指南。
2) 在Composer配置文件中配置QPM
使用Composer的项目,在项目目录下通常有composer.json文件。
可参考如下配置。
{ "require": { "monolog/monolog": "1.0.*", "comos/qpm":"0.3.*" } }
其中
"comos/qpm":"0.3.*"
表示依赖 comos/qpm 0.3.x版本。
3) 安装QPM
准备好composer.json, 执行 composer install 后,即可在 vendor/comos 找到qpm
4) 运行
运行前,脚本须先加载compser autoload.php文件。
例 test.php:
<?phprequire __DIR__.'/vendor/autoload.php';$pid = qpm\process\Process::current()->getPid();echo "PID: $pid\n";
执行 php test.php,终端输出 PID: 11210 (进程号)。
直接下载QPM
1) 从github releases 下载最新稳定版本。
例如 0.3.0版本。
2) 解压到项目目录。
tar zxvf 0.3.0.tar.gz
3) 注册自己编写的autoloader并运行。
由于qpm遵循psr-4,需要依赖autoloading机制加载类,如果项目没有注册适合的autoloader,用户需要自行实现autoloader。
例如 test1.php:
<?php spl_autoload_register(function ($class) { $prefix = 'qpm\\'; $baseDir = __DIR__ . '/qpm-0.3.0/library'; $len = strlen($prefix); if (strncmp($prefix, $class, $len) !== 0) { return; } $relativeClass = substr($class, $len); $file = $baseDir . str_replace('\\', '/', $relativeClass) . '.php'; if (file_exists($file)) { require $file; } }); $pid = qpm\process\Process::current()->getPid(); echo "PID: $pid\n";
执行 php test1.php,终端输出 PID: 11210 (进程号)。

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),
