In this paper, we share the specific code of PHP Wechat Public Number Development for your reference. The details are as follows.
Running through three passes
- Impode (“,”, array) Array Variable String Array cannot be saved to the database
- Explode (“,””, str) string variable array
- Array_rand ($arr, n) randomly takes out n single items in an array
The core code is as follows:
public function responseMsg()
{
//get post data, May be due to the different environments
$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
//extract post data
if (!empty($postStr)){
$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$fromUsername = $postObj->FromUserName;
$toUsername = $postObj->ToUserName;
$type = $postObj->MsgType;
$customevent = $postObj->Event;
$latitude = $postObj->Location_X;
$longitude = $postObj->Location_Y;
$keyword = trim($postObj->Content);
