概述
azjezz/psl 是一个PHP标准库（PHP Standard Library）项目。这个项目是一个为PHP程序员提供的一致性、集中化且类型良好的API集合。它受到hhvm/hsl的启发，旨在为PHP开发提供的一套现代化、一致性、集中化、良好类型化、非阻塞的 API 集合工具集，从而简化开发过程并提高代码的可维护性和可移植性。提高 PHP 编程的效率和一致性，通过提供一套标准化的 API 来简化开发过程。
特点
-
目标 ：为PHP程序员提供一套标准的、集中的、类型良好的API。
-
灵感来源 ：该项目受到
hhvm/hsl的启发，后者是HHVM（HipHop Virtual Machine，一种由Facebook开发的PHP执行引擎）的标准库。 -
功能 ：通过其API集合，该库提供了多种功能。如：异步编程支持（通过Async命名空间）、TCP连接管理（通过TCP命名空间）、输入输出操作（通过IO命名空间）、Shell命令执行（通过Shell命名空间）以及字符串处理（通过Str命名空间）等。
-
安装 ：该项目支持通过Composer进行安装，这是PHP的一个依赖管理工具，允许你声明项目所依赖的外部库。
-
集成 ：该项目提供了与
Psalm和PHPStan的集成支持，Psalm是一个PHP静态分析工具，而PHPStan是另一个流行的PHP静态分析工具，这有助于开发者在开发过程中发现并修复潜在的问题。
安装
安装 libsodium
1sudo /usr/local/php-8.3.1/bin/pecl install -f libsodium
请参考： PHP官方现代化核心加密库 Sodium
安装 azjezz/psl
1/usr/local/php-8.3.1/bin/php composer require azjezz/psl
异步协作
协作式多工（Cooperative Multitasking） ：是一种多工处理方式，多工是使电脑能同时处理多个程序的技术，相对于抢占式多工（Preemptive multitasking）由操作系统决定任务切换时机。协作式多工要求每一个运行中的程序，定时放弃(yield)自己的执行权利，告知操作系统可让下一个程序执行[1][2]，因为需要程序之间合作达到调度，故称作协作式多工。
在多工处理中，处理器(CPU)会在相对于用户来说极短的时间内，依次分配处理能力给不同的程序，以实现看似同时运行多个程序的效果。举例来说，当你同时使用浏览器浏览网页和播放MP3音乐时，CPU会快速切换处理能力，让你感觉网页在下卷时音乐仍在播放。然而，如果其中一个程序出现问题，例如因为设计不良或出现故障而无法释放执行权，这样的行为会导致整个操作系统停顿，甚至死机。因此，在开发软件时，需要注意程序的质量和稳定性，避免出现此类问题，以确保系统的稳定运行。
Async组件构建在RevoltPHP之上，这使得它与Amphp和其他使用相同事件循环的库兼容。
RevoltPHP：
https://github.com/revoltphp/event-loop
简单使用
1Async\main(static function(): int {
2 $watcher = Async\Scheduler::onSignal(SIGINT, function (): never {
3 IO\write_error_line('SIGINT received, stopping...');
4 exit(0);
5 });
6
7 Async\Scheduler::unreference($watcher);
8
9 IO\write_line('Hello, World!');
10
11 [$version, $connection] = Async\concurrently([
12 static fn() => Shell\execute('php', ['-v']),
13 static fn() => TCP\connect('172.30.237.24', 2023),
14 ]);
15 $messages = Str\split($version, "\n");
16 IO\write_line('php, -v!'.json_encode($messages));
17 foreach($messages as $message) {
18 $connection->writeAll($message);
19 }
20
21 $connection->close();
22
23 return 0;
24});
输出
1Hello, World! 2php, -v!["PHP 8.3.1 (cli) (built: Dec 25 2023 21:14:50) (NTS)","Copyright (c) The PHP Group","Zend Engine v4.3.1, Copyright (c) Zend Technologies",""]
