  'openid' varchar(30) NOT NULL,
  'username' varchar(20) NOT NULL,
  'telphone' varchar(16) NOT NULL,
  PRIMARY KEY ('id'),

$result = mysql_query("UPDATE  'wx_user' SET 'telphone' = '1369*****32' WHERE 'openid' = 'FJDAKFJAFDFA';");
mysql_close($con);

查询数据

$con = mysql_connect("localhost:3306","root","root");

$result = mysql_query("SELECT * FROM 'wx_user' WHERE 'openid' = 'FJDAKFJAFDFA' ");
while($row = mysql_fetch_arrary($result)){
  echo $row['username']." ".$row['telphone'];
  echo "
