第一个if语句里有语法错误吗？面向对象的就没错，面向对象的就错了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=wx5d4c7d2e8ffd5793&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']; } }}

面向对象的就没错，面向对象的就错了
看不懂你要问什么
看下$resu是什么?
话说你的mysql_query就能这么直接用了?
既然都面向对象了还手动引用数据库
