本文實例講述了PHP swoole和redis異步任務實現方法。分享給大家供大家參考，具體如下：

redis異步任務

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異步任務

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);
}

比較

redis異步任務日志

swoole異步任務日志

通過對比任務日志我們可以看到，由于swoole開了4個進程執行異步任務，所以處理異步任務的效率大概是redis的四倍，如果swoole只開一個進程的話，效率和redis幾乎沒有什么差別。
