4 php7.4中开发一个websocket 聊天相关配置调用

在config中创建config.php，用来保存相应的配置

php 复制代码

<?php
// 配置常量
define('ENV_DEV', 'dev');
define('ENV_PRO', 'pro');

// 当前环境（开发环境或生产环境）
$env = ENV_DEV; // 修改为ENV_DEV以切换到开发环境

// OSS配置 这里是阿里云的配置
$oss = [
    'accessKeyId' => '',
    'accessKeySecret' => '',
    'endpoint' => 'oss-cn-shanghai.aliyuncs.com',
    'bucket' => ''
];

// MySQL配置
$mysql_config = [
    ENV_DEV => ['host' => 'localhost', 'user' => 'root', 'port' => 3306, 'password' => 'asd123', 'database' => 'mychat'],
    ENV_PRO => ['host' => 'localhost', 'user' => 'chat', 'port' => 3306, 'password' => 'asd123', 'database' => 'chat']
];

// Redis配置
$redis_config = [
    ENV_DEV => ['host' => 'localhost', 'port' => 6379, 'auth' => '123456', 'db' => 2],
    ENV_PRO => ['host' => 'localhost', 'port' => 6379, 'auth' => '123456', 'db' => 2]
];

// WebSocket配置 放上自己的配置
$port = 3300;//端口号
$wss = $env === ENV_DEV ? "websocket://127.0.0.1:$port" : "websocket://0.0.0.0:$port";
$client_ws = $env === ENV_DEV ? "ws://127.0.0.1:$port" : "wss://xxx.zzz.cn/wss";

// 获取数据库配置
function getDbConfig() {
    global $env, $mysql_config;  // 使用全局变量

    $dbConfig = $mysql_config[$env];
    
    try {
        $pdo = new PDO(
            "mysql:host={$dbConfig['host']};port={$dbConfig['port']};dbname={$dbConfig['database']}",
            $dbConfig['user'], 
            $dbConfig['password']
        );
        $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        return $pdo;
    } catch (PDOException $e) {
        echo "数据库连接失败: " . $e->getMessage();
        return null;
    }
}
// 获取Redis配置（不再需要传递参数）
function getRedisConfig() {
    global $env, $redis_config;  // 使用全局变量
    $redisConfig = $redis_config[$env];
    $redis = new Redis();
    try {
        $redis->connect($redisConfig['host'], $redisConfig['port']);
        $redis->auth($redisConfig['auth']);
        $redis->select($redisConfig['db']);
        return $redis;
    } catch (Exception $e) {
        echo "Redis连接失败: " . $e->getMessage();
        return null;
    }
}

要src 中写入几个文件，用来获取历史聊天，好友例表，撤回记录等操作。
