workerman-redis組件-select

发布时间：2021-12-25 21:41:43编辑：雪饮阅读（）

select在redis中是值選擇一個數據庫，傳入數據庫下標，下標是從0開始的，默認總共16個庫

那麽實例如：

<?php

use Workerman\Worker;

use Workerman\Redis\Client;

use Workerman\Connection\TcpConnection;

use Workerman\Timer;

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

$worker = new Worker('http://0.0.0.0:6161');

$worker->onWorkerStart = function() {

};

$worker->onMessage = function(TcpConnection $connection, $data) {

$redis = new Client('redis://127.0.0.1:6379');

$redis->auth("xy220807",function($result){

var_dump($result);

});

// 省略回调

$redis->select(2);

$redis->select('test', function ($result, $redis) {

// select参数必须为数字，所以这里$result为false

var_dump($result, $redis->error());

});

};

Worker::runAll();

實例運行並被客戶端請求后如：

[root@localhost www.fpm.com]# /usr/local/php734/bin/php channelServer.php start

Workerman[channelServer.php] start in DEBUG mode

----------------------------------------- WORKERMAN -----------------------------------------

Workerman version:4.0.22 PHP version:7.3.4

------------------------------------------ WORKERS ------------------------------------------

proto user worker listen processes status

tcp root none http://0.0.0.0:6161 1 [OK]

---------------------------------------------------------------------------------------------

Press Ctrl+C to stop. Start success.

bool(true)

bool(false)

string(43) "ERR value is not an integer or out of range"
