$query="Select * from authorized_users where name= '$userid' and password='{sha1($password)}'"; ------解决方案-------------------- $query='Select * from authorized_users where name= "'.$userid.'" and password=sha1("'.$password.'")';
语法正确，但可读性不强
$query="Select * from authorized_users where name='$userid' and password=sha1('$password')";
这样是不是清爽些？
