Examples are as follows:

https://api.weixin.qq.com/cgi-bin/user/get?access_token=ACCESS_TOKEN

Copy after login

{
  "total":23000,
  "count":10000,
  "data":{"
     openid":[
        "OPENID1",
        "OPENID2",
        ...,
        "OPENID10000"
     ]
   },
   "next_openid":"NEXT_OPENID1"
}

Copy after login

https://api.weixin.qq.com/cgi-bin/user/get?access_token=ACCESS_TOKEN&next_openid=NEXT_OPENID1

$url = "https://api.weixin.qq.com/cgi-bin/user/get?access_token=$access_token";
$result = https_request($url);
$jsoninfo = json_decode($result, true);
var_dump($result);
