Verify the token php code of the token, reply to text, and push messages,

The examples in this article share with you the classes used to verify tokens, reply text and text, and push messages to users. The specific code is as follows:

<?phpclass Wechat{  private $data = array();  public function __construct($token){    $this -> auth($token, $wxuser) || exit;    if(IS_GET){      echo($_GET['echostr']);      exit;    }else{      $xml = file_get_contents("php://input");        $xml = new SimpleXMLElement($xml);  //file_put_contents('/var/log/test.txt', $xml,FILE_APPEND);      $xml || exit;      foreach ($xml as $key => $value){        $this -> data[$key] = strval($value);      }    }  }  public function request(){    return $this -> data;  }  public function response($content, $type = 'text', $flag = 0){    $this -> data = array('ToUserName' => $this -> data['FromUserName'], 'FromUserName' => $this -> data['ToUserName'], 'CreateTime' => NOW_TIME, 'MsgType' => $type);    $this -> $type($content);    $this -> data['FuncFlag'] = $flag;    $xml = new SimpleXMLElement('<xml></xml>');    $this -> data2xml($xml, $this -> data);    exit($xml -> asXML());  }  private function text($content){    $this -> data['Content'] = $content;  }  private function music($music){    list($music['Title'], $music['Description'], $music['MusicUrl'], $music['HQMusicUrl']) = $music;    $this -> data['Music'] = $music;  }  private function news($news){    $articles = array();    foreach ($news as $key => $value){      list($articles[$key]['Title'], $articles[$key]['Description'], $articles[$key]['PicUrl'], $articles[$key]['Url']) = $value;      if($key >= 9){        break;      }    }    $this -> data['ArticleCount'] = count($articles);    $this -> data['Articles'] = $articles;  }  private function transfer_customer_service($content){    $this -> data['Content'] = '';  }  private function data2xml($xml, $data, $item = 'item'){    foreach ($data as $key => $value){      is_numeric($key) && $key = $item;      if(is_array($value) || is_object($value)){        $child = $xml -> addChild($key);        $this -> data2xml($child, $value, $item);      }else{        if(is_numeric($value)){          $child = $xml -> addChild($key, $value);        }else{          $child = $xml -> addChild($key);          $node = dom_import_simplexml($child);          $node -> appendChild($node -> ownerDocument -> createCDATASection($value));        }      }    }  }  private function auth($token){    $signature = $_GET["signature"];    $timestamp = $_GET["timestamp"];    $nonce = $_GET["nonce"];    $tmpArr = array($token, $timestamp, $nonce);    sort($tmpArr, SORT_STRING);    $tmpStr = implode($tmpArr);    $tmpStr = sha1($tmpStr);    if(trim($tmpStr) == trim($signature)){      return true;    }else{      return false;    }    return true;  }}?>
