hGet
返回哈希表中指定字段的值。
如果给定的字段或 key 不存在时,返回 null。
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) {
$redis = new Client('redis://127.0.0.1:6379');
$redis->hGet('h', 'key1', function ($result) {
var_dump($result);
});
};
Worker::runAll();
實例運行並有http客戶端訪問如:
[root@localhost www.fpm.com]# /usr/local/php734/bin/php channelServer.php start
Workerman[channelServer.php] start in DEBUG mode
