使用workerman加速任意项目

看源码原理:
第一、禁止 php 自带函数的同时编写新的函数。
第二、提供新的启动入口使用workerman，同时把框架的核心加载代码，稍作修
改。这样就完美的接替了 php-fpm 。代码常驻内存，性
能提升还是肉眼可见的。当然这个里面的替换思路还是很有意思的。
第三、装上 event扩展 ，性能提升一个量级 ， I/O 通知机制有效地安排基于 I/O、时间和信号的事件， epoll linux内核支持 io多路复用

event扩展安装 此处忽略

php.ini 通过 disable_functions 禁用一些函数

disable_functions =header,header_remove,http_response_code,
setcookie,session_create_id,session_id,session_name,
session_save_path,session_status,session_start,
session_write_close,session_regenerate_id,set_time_limit

start.php 启动文件

<?php

require_once __DIR__ . '/vendor/autoload.php';

use Adapterman\Adapterman;
use Workerman\Worker;

Adapterman::init();

$http_worker                = new Worker('http://0.0.0.0:8080');
$http_worker->count         = 8;
$http_worker->name          = 'AdapterMan';

$http_worker->onWorkerStart = static function () {
    //init();
    require __DIR__.'/start.php';
};

$http_worker->onMessage = static function ($connection, $request) {

    $connection->send(run());
};

Worker::runAll();

把session，cookies等使用封装函数代替了，是个不错的想法，但是不能全部直接移植使用，估计还需要更改一些东西

swoole4 是通过 hook 原生函数的方式去兼容各种库代码

AdapterMan
https://github.com/joanhey/AdapterMan/blob/master/src/Adapterman.php#L39

<?php

namespace Adapterman;

use Exception;

class Adapterman
{
    public const VERSION = "0.5.3";

    public const NAME = "Adapterman v". self::VERSION;
    
    private const FUNCTIONS = ['header', 'header_remove', 'http_response_code', 'setcookie', 'session_create_id', 'session_id', 'session_name', 'session_save_path', 'session_status', 'session_start', 'session_write_close', 'session_regenerate_id', 'set_time_limit'];

    public static function init(): void
    {
        try {
            self::checkVersion();
            self::checkFunctionsDisabled();
            
            // OK initialize the functions
            require __DIR__ . '/AdapterFunctions.php';

        } catch (Exception $e) {
            fwrite(STDERR, self::NAME . ' Error:' . PHP_EOL);
            fwrite(STDERR, $e->getMessage());
            exit;
        }
        
        fwrite(STDOUT, self::NAME . ' OK' . PHP_EOL);
    }

    /**

            throw new Exception("* PHP version must be 8 or higher." . PHP_EOL . "* Actual PHP version: " . \PHP_VERSION . PHP_EOL);
        }
    }

    /**

     * @throws Exception
     * @return void
     */
    private static function checkFunctionsDisabled(): void
    {
 
        foreach (self::FUNCTIONS as $function) {
            if (\function_exists($function)) {
                throw new Exception("Functions not disabled in php.ini." . PHP_EOL . self::showConfiguration());
            }
        }
    }

    private static function showConfiguration(): string
    {
        $inipath = \php_ini_loaded_file();
        $methods = \implode(',', self::FUNCTIONS);

        return "Add in file: $inipath" . PHP_EOL . "disable_functions=$methods" . PHP_EOL;
    }
}

必须php8以上项目
用上workerman常驻内存 性能能提升一个量级

下图为laravel8 提升，其他项目比如thinkphp lumen Yii2 Slim 等 都可用此项目基础于 workerman 加速。
