NSQ client for php7 . QQ Group : 616063018



intall :

Dependencies: libevent  (apt-get install libevent-dev ,yum install libevent-devel)

pecl install nsq


1. sudo phpize
2. ./configure 
3. make  
4. make install  

add in your php.ini:

extension =;


if has the error "configure: error: Cannot find libevent headers" you should run :

./configure --with-php-config=/usr/local/php-7.2.12/bin/php-config --with-libevent-path=/usr/local/libevent-2.1.8-stable/ 

Example for pub:

// Normal publish 
$nsqdAddr = array(

$nsq = new Nsq();
$isTrue = $nsq->connectNsqd($nsqdAddr);

for($i = 0; $i < 10000; $i++){
    $nsq->publish("test", "nihao");

// Deferred publish 
//function : deferredPublish(string topic,string message, int millisecond); 
//millisecond default : [0 < millisecond < 3600000]

$deferred = new Nsq();
$isTrue = $deferred->connectNsqd($nsqdAddr);
for($i = 0; $i < 20; $i++){
    $deferred->deferredPublish("test", "message daly", 3000); 

Example for sub:



$nsq_lookupd = new NsqLookupd(""); //the nsqlookupd http addr
$nsq = new Nsq();
$config = array(
    "topic" => "test",
    "channel" => "struggle",
    "rdy" => 2,                //optional , default 1
    "connect_num" => 1,        //optional , default 1   
    "retry_delay_time" => 5000,  //optional, default 0 , if run callback failed, after 5000 msec, message will be retried
    "auto_finish" => true, //default true

$nsq->subscribe($nsq_lookupd, $config, function($msg,$bev){ 

    echo $msg->payload."\n";
    echo $msg->attempts."\n";
    echo $msg->messageId."\n";
    echo $msg->timestamp."\n";


Nsq Object

  • connectNsqd($nsqdAddrArr)
    publish use, You can also use it for health check;

  • closeNsqdConnection()
    close connecNsqd's socket

  • publish($topic,$msg)

  • deferredPublish($topic,$msg,$msec)

  • subscribe($nsq_lookupd,$config,$callback)

  • conn_timeout = 100
    connection timeout for connectNsqd() in milliseconds

Message Object

The following properties and methods are available on Message objects produced by a Reader instance.

  • timestamp
    Numeric timestamp for the Message provided by nsqd.
  • attempts
    The number of attempts that have been made to process this message.
  • messageId
    The opaque string id for the Message provided by nsqd.
  • payload
    The message payload as a Buffer object.
  • finish($bev,$msg->messageId)
    Finish the message as successful.
  • touch($bev,$msg->messageId)
    Tell nsqd that you want extra time to process the message. It extends the soft timeout by the normal timeout amount.

Tips :

  1. If you need some variable in callback ,you should use 'use' :
$nsq->subscribe($nsq_lookupd, $config, function($msg,$bev) use ($you_variable){ 

    echo $msg->payload;

  1. Requeue/Retry -- if you whant to retry your message when callback have something wrong, just throw any Exception , example:

$nsq->subscribe($nsq_lookupd, $config, function($msg){ 
        echo $msg->payload . " " . "attempts:".$msg->attempts."\n";
        //do something
    }catch(Exception $e){

        if($msg->attempts < 3){
            //the message will be retried after you configure retry_delay_time
            throw new Exception("");
            echo $e->getMessage();


  1. If you want to increase your message timeout and heartbeats time ,Two steps are needed:
    #1 when nsqd startup you should set command line option:

    nsqd --lookupd-tcp-address= --max-heartbeat-interval=1m30s --msg-timeout=10m30s

    #2 And , you should use identify config. For details, see the identify example file.

  1. If your have strong consuming ability ,you can add you rdy num and connect num

  2. If your execution time is more than 1 minute, you should use 'touch()' function

  3. Do not support calling publish or deferredPublish in subscribe function, please use nsqd's HTTP interface.
