小编之前发布过一篇“微信公众平台开发|发送模板消息”的文章，这篇只是发送给某个用户的，那么如何群发给关注该公众号的所有用户呢？下面我们来探讨一下。
最近关注了一个公众号，偶尔会给我发送一些信息，看了这公众号为服务号，知道服务号一个月只能发布4篇文章，那怎么现在可以天天给我发送带链接的消息的？小编就好奇去研究了一下，知道这就是模板消息，那怎么是群发的呢？看了一下微信公众平台的开发文档，有一篇“获取用户列表”的文章，那就清楚了，通过获取关注该公众号的用户，然后分别发送模板消息。下面见代码：

ClassWeChatSendMsg{

function__construct(){
$this->appid="xxx";
$this->secrect="xxx";
}

$curl=curl_init();
curl_setopt($curl,CURLOPT_URL,$url);
curl_setopt($curl,CURLOPT_SSL_VERIFYPEER,FALSE);
curl_setopt($curl,CURLOPT_SSL_VERIFYHOST,FALSE);

curl_setopt($curl,CURLOPT_POST,1);
curl_setopt($curl,CURLOPT_POSTFIELDS,$data);
}
curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
$output=curl_exec($curl);
curl_close($curl);
return$output;
}

publicfunctiongetAccessToken(){
$url="https://api./cgi-bin/token?grant_type=client_credential&appid=".$this->appid."&secret=".$this->secrect;
$res=json_decode($this->httpRequest($url),true);
return$res['access_token'];
}
//获取用户列表(openid)
publicfunctiongetUserOpenidList($token){
$url="https://api./cgi-bin/user/get?access_token=".$token;
$result=$this->httpRequest($url);
returnjson_decode($result,true);
}
/***

publicfunctionsendTemplateMessage($token,$data=""){

$result=$this->httpRequest($url,$data);
returnjson_decode($result,true);
}
}
sendTemplateMessage.php
require_once('WeChatSendMsg.class.php');
$sendMsg=newWeChatSendMsg();
$token=$sendMsg->getAccessToken();//获取token
$users=$sendMsg->getUserOpenidList($token);//获取用户列表
$data=array(
"template_id"=>"iq91YDi7QaACAyZlm7RaboyNEHDdU2YizPju7rshUq8",//模板ID
"url"=>"",//链接地址
"data"=>array(//模板内容
"name"=>array("value"=>"lrfun博客","color"=>"#173177"),
"remark"=>array("value"=>"^_^欢迎大家关注转载！","color"=>"#173177")
)
);
foreach($users['data']['openid']as$v){
$data['touser']=$v;
$result=$sendMsg->sendTemplateMessage($token,json_encode($data));
print_r($result);
}
