生产者代码：
<?php
set_time_limit(0);
include_once('RabbitMQCommand.php'); $configs = array('host'=>'192.168.0.156','port'=>5672,'username'=>'xp','password'=>'xp','vhost'=>'/');
$exchange_name = 'class-e-1';
$queue_name = 'class-q-1';
$route_key = 'class-r-1';
$ra = new RabbitMQCommand($configs,$exchange_name,$queue_name,$route_key);
for($i=0;$i<=10000000;$i++){
$ra->send(date('Y-m-d H:i:s',time()));
}
exit();
消费者代码：
<?php
error_reporting(0);
include_once('RabbitMQCommand.php'); $configs = array('host'=>'192.168.0.156','port'=>5672,'username'=>'xp','password'=>'xp','vhost'=>'/');
$exchange_name = 'class-e-1';
$queue_name = 'class-q-1';
$route_key = 'class-r-1';
$ra = new RabbitMQCommand($configs,$exchange_name,$queue_name,$route_key); class A{
function processMessage($envelope, $queue) {
$msg = $envelope->getBody();
$envelopeID = $envelope->getDeliveryTag();
$pid = posix_getpid();
file_put_contents("/app/bossadmin/log{$pid}.log", $msg.'|'.$envelopeID.''."\r\n",FILE_APPEND);
$queue->ack($envelopeID);
}
}
$a = new A(); $s = $ra->run(array($a,'processMessage'),false);
测试结果：
开了6个生产者，6个消费者，生产6000W条数据，执行了4个小时，消费者基本即时处理完毕

总结：
RabbitMQ在PHP消费端请求连接后，如果有消息会主动轮询各个消费端，这让php作为守护进程的性能还可以。实际运行较长的时间，cpu内存等数据也都还可以。
而httpsqs需要消费端不断去请求httpsqs服务，守护进程的性能损耗就比较高。
