还有一种sub pub消息

消息生产端

<?php

$channelName = "testPubSub";
$channelName2 = "testPubSub2";
//向指定频道发送消息
try {
    $redis = new Redis();
    $redis->connect('127.0.0.1', 6379);
    for ($i = 0; $i < 5; $i++) {
        $data = array('key' => 'key'.$i, 'data' => 'testdata');
        $ret = $redis->publish($channelName, json_encode($data));
        print_r($ret);
    }

} catch (Exception $e) {
    echo $e->getMessage();
}

<?php

//声明测试频道名称
$channelName = "testPubSub";
$channelName2 = "testPubSub2";
$redis = new Redis();
//建立一个长链接
$redis->connect('127.0.0.1', 6379);
try {

    $redis->subscribe(array($channelName, $channelName2), function ($redis, $chan, $msg) {
        echo "channel:".$chan.",message:".$msg."\n";
    });
} catch (Exception $e) {
    echo $e->getMessage()."\n";
}
