setBit

对 key 所储存的字符串值，设置或清除指定偏移量上的位(bit)。

返回值为0或1，是修改前的值。

實例：

<?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');

global  $offset;

$worker->onWorkerStart = function() {

    global  $offset;

    $offset=0;

};

 

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

    global $offset;

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

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

        var_dump("auth:");

        var_dump($result);

    });

    $redis->set('key', "*");    // ord("*") = 42 = 0x2f = "0010 1010"

    $redis->setBit('key', $offset, 1, function ($result) {

        global $offset;

        var_dump("setBit ".$offset.":");

        var_dump($result); // 0

        $offset++;

    }) ;

};

 

Worker::runAll();

實例運行並有http客戶端的7次訪問后如：

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

Workerman[channelServer.php] start in DEBUG mode
