PHP swoole和redis异步任务实现方法分析

本文实例讲述了php swoole和redis异步任务实现方法。分享给大家供大家参考，具体如下：

redis异步任务

interface.php

<?php
for($i=0;$i<100;$i++){
  $msg = "zhezhao[".$i."]";
  $redis = new redis();
  $redis->connect("127.0.0.1");
  $redis->publish("test",$msg);
  $redis->close();
}

handler.php

<?php
$redis = new redis();
$redis->connect("127.0.0.1");
$redis->subscribe(array("test"), 'handlefun');
function handlefun($redis, $chan, $data) {
  write($data);
}
function write($data){
  $path = "/tmp/maillist-redis.log";
  $str = "[".date("y-m-d h:i:s")."]".$data;
  $str .= php_eol;
  file_put_contents($path,$str,file_append);
}

swoole异步任务

interface.php

<?php
for($i=0;$i<100;$i++){
  $msg = "zhezhao[".$i."]";
  $client = new swoole_client(swoole_sock_tcp);
  $client->connect('127.0.0.1', 9501, 0.5);
  $client->send($msg);
  $client->close();
}

handler.php

<?php
$serv = new swoole_server("127.0.0.1", 9501);
$serv->set(array('task_worker_num' => 4));
$serv->on('receive', function($serv, $fd, $from_id, $data) {
  $task_id = $serv->task($data);
});
$serv->on('task', function ($serv, $task_id, $from_id, $data) {
  handle($data);
  $serv->finish($data);
});
$serv->start();
function handle($data){
  sleep(2);
  maillog("send mail successfully to $data");
}
function maillog($str){
  $path = "/tmp/maillist.log";
  $str = "[".date("y-m-d h:i:s")."]".$str;
  $str .= php_eol;
  file_put_contents($path,$str,file_append);
}

比较

redis异步任务日志

swoole异步任务日志

通过对比任务日志我们可以看到，由于swoole开了4个进程执行异步任务，所以处理异步任务的效率大概是redis的四倍，如果swoole只开一个进程的话，效率和redis几乎没有什么差别。
