PHP WeChat Development, ask Daniel to look at the problem there

Is there a syntax error in the first if statement?                   Object-oriented is right, the object-oriented is the wrong class Wechat_base_api{public function Get_access_token () {require_once (' connect.php ');                   $tim =time ();                  $sql = "SELECT * from Get_access_token where id=0 and updated_time> $tim";                  $resu = mysql_query ($sql);                      if ($resu) {$row =mysql_fetch_assoc ($resu);                      $access _token= $row [' content '];                                       return $access _token; }else{$url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=wx5d4c                                       7d2e8ffd5793&secret=4379ef7213c36eae5dc2ab91f9f6aced ";                                          $access _token_arr = $this->https_request ($url);                    $access _token= $access _token_arr[' Access_token ';                     $newtime =time () +7200; $SQLL = "Update Get_access_token set content= ' {$access _token} ', Updated_time= $newtime where id=0 ";                       mysql_query ($SQLL);                                                           return $access _token_arr[' Access_token ']; }            }}

Object-oriented is right, object-oriented is wrong

I don't know what you're asking.

Look $resu what it is.
mysql_queryso you can use it so directly?

Since all objects are object-oriented, the database is also referenced manually
