 $TMPSTR = implode ($TMPARR);
 
 $TMPSTR = SHA1 ($TMPSTR); if ($tmpStr = = $signaturE) {return true;
 }else{return false;

 }}}?>

3. Invoke the reply-to information method
  Comment out $wechatobj->valid () in the wx_sample.php file, and add a phrase "$WECHATOBJ-> Responsemsg (); ".

<?php/** * WeChat PHP Test * *//define Your token ("define", "token");
$WECHATOBJ = new Wechatcallbackapitest (); $WECHATOBJ->valid ();//interface Validation $WECHATOBJ->responsemsg ()//Call Reply message method class Wechatcallbackapitest {public

 function valid () {$echoStr = $_get["Echostr"];
 Valid signature, option if ($this->checksignature ()) {echo $echoStr;
 Exit The Public Function responsemsg () {//get post data, May is due to the different environments $postStr = $GLOBALS ["H

 Ttp_raw_post_data "];
  Extract post Data if (!empty ($POSTSTR)) {/* Libxml_disable_entity_loader is to prevent XML eXternal entity injection,
  The best way is to check the validity of XML by yourself/Libxml_disable_entity_loader (TRUE);
 $POSTOBJ = simplexml_load_string ($postStr, ' simplexmlelement ', libxml_nocdata);
 $fromUsername = $POSTOBJ->fromusername;
 $toUsername = $POSTOBJ->tousername;
 $keyword = Trim ($postObj->content);
 $time = time (); $TEXTTPL = "<xml> <tousername><! [cdata[%s]]></tousername> <fromusername><! [cdata[%s]]></fromusername> <CreateTime>%s</CreateTime> <msgtype><! [cdata[%s]]></msgtype> <content><! 
 [cdata[%s]]></content> <FuncFlag>0</FuncFlag> </xml> ";
  if (!empty ($keyword)) {$msgType = "text";
  $CONTENTSTR = "Welcome to WeChat world!";
  $RESULTSTR = sprintf ($TEXTTPL, $fromUsername, $toUsername, $time, $msgType, $CONTENTSTR);
 Echo $resultStr;
 }else{echo "Input something ...";
 }}else {echo "";
 Exit } Private Function Checksignature () {//You must define TOKEN by yourself if (!defined ("TOKEN")) {throw new Ex
 Ception (' TOKEN is not defined! ');
 } $signature = $_get["signature"];
 $timestamp = $_get["timestamp"];
 
 $nonce = $_get["nonce"];
 $token = token;
 $TMPARR = Array ($token, $timestamp, $nonce);
 Use sort_string the rule SORT ($TMPARR, sort_string);
 $TMPSTR = implode ($TMPARR); $tmpStr = SHA1 ($TMPSTR);
 if ($tmpStr = = $signature) {return true;
 }else{return false;


 }}}?>

4. Keyword automatic reply and attention reply
$keyword holds the text message from the user's micro-mail.
Official developer Documentation:https://mp.weixin.qq.com/wiki/home/index.html(Message management-Receive message-Receive event push-1. Concern/cancellation of attention events)

There are two differences between the attention event and the general text message, one is that the Msgtype value is an event, and the other is that the subscribe value is added. Since the official document (the original wx_sample.php) did not extract this parameter, we need to extract it ourselves. Add two variables $msgtype and $event to the program.

<?php/** * WeChat PHP Test * *//define Your token ("define", "token");
$WECHATOBJ = new Wechatcallbackapitest (); $WECHATOBJ->valid ();//interface Validation $WECHATOBJ->responsemsg ()//Call Reply message method class Wechatcallbackapitest {public

 function valid () {$echoStr = $_get["Echostr"];
 Valid signature, option if ($this->checksignature ()) {echo $echoStr;
 Exit The Public Function responsemsg () {//get post data, May is due to the different environments $postStr = $GLOBALS ["H

 Ttp_raw_post_data "];
  Extract post Data if (!empty ($POSTSTR)) {/* Libxml_disable_entity_loader is to prevent XML eXternal entity injection,
  The best way is to check the validity of XML by yourself/Libxml_disable_entity_loader (TRUE);
 $POSTOBJ = simplexml_load_string ($postStr, ' simplexmlelement ', libxml_nocdata);
 $fromUsername = $POSTOBJ->fromusername;
 $toUsername = $POSTOBJ->tousername;
 $keyword = Trim ($postObj->content);
 $time = time (); $msgType = $POSTOBJ->msgtype;//Message classType $event = $POSTOBJ->event;//Time type, subscribe (subscription), unsubscribe (unsubscribe) $TEXTTPL = "<xml> <tousername><! [cdata[%s]]></tousername> <fromusername><! [cdata[%s]]></fromusername> <CreateTime>%s</CreateTime> <msgtype><! [cdata[%s]]></msgtype> <content><! 
  
 [cdata[%s]]></content> <FuncFlag>0</FuncFlag> </xml> "; Switch ($msgType) {case "event": if ($event = = "Subscribe") {$contentStr = "Hi, please pay attention to the Sea Fairy daily necessities!". \ n "." Reply Number ' 1 ' to find out shop address. "." \ n "." 
  Reply to the number ' 2 ' to understand the type of product. ";}
  Break Case "text": Switch ($keyword) {case "1": $contentStr = "store Address:". " \ n "." 
  First row of basement of new Dongsheng Market, No. No. 233 Shanxi Road, Jianggan, Hangzhou, China.
  Break Case "2": $contentStr = "type of commodity:". \ n "." Cups, bowls, cotton swabs, buckets, garbage cans, dishwashing towel (brush), mop, Broom, "."

  Break
  Default: $contentStr = "Sorry, I will reply to your content later";
 } break;
 } $msgType = "text";
 $RESULTSTR = sprintf ($TEXTTPL, $fromUsername, $toUsername, $time, $msgType, $CONTENTSTR); Echo $resULTSTR;
 }else {echo "";
 Exit } Private Function Checksignature () {//You must define TOKEN by yourself if (!defined ("TOKEN")) {throw new Ex
 Ception (' TOKEN is not defined! ');
 } $signature = $_get["signature"];
 $timestamp = $_get["timestamp"];
 
 $nonce = $_get["nonce"];
 $token = token;
 $TMPARR = Array ($token, $timestamp, $nonce);
 Use sort_string the rule SORT ($TMPARR, sort_string);
 $TMPSTR = implode ($TMPARR);
 
 $TMPSTR = SHA1 ($TMPSTR);
 if ($tmpStr = = $signature) {return true;
 }else{return false;
