php - 意外的T_CATCH，预期为T_FUNCTION

Question

今天，在尝试编写此User类时，我在下面突出显示的行上遇到了上述错误，想知道您对此有何想法。

class User {
  public $username;
  public $password;
  public $user_info;
  public $connection;

  function __construct($username) {
   $connection = new Database();
   try {
   $user_info = $connection->query("SELECT * FROM `users` WHERE `username` = '$username'");
   if ($user_info == null) {
    throw new Exception("Could not find user details, please try again later!");
   }
   ***} catch (Exception $login) {***
    die($login->getMessage());
   }
   session_start();
   $_SESSION["dgs_tech"] = $user_info;
  }

  function update_info() {
   $user_info = $connection->query("SELECT * FROM `users` WHERE `username` = '$username'");
   if ($user_info == null) {
    throw new Exception("Could not find user details, please try again later!");
   }
   } catch (Exception $login) {
    die($login->getMessage());
   }
   $_SESSION{"dgs_tech"] = $user_info;
  }

  function return_info() {
   $text = "<p>"
   foreach($user_info as $name => $item) {
    $text += "<h1>$name:</h1>$item<br/>";
   }
   $text += "</p>";
   return $text;
  }
 }

我认为此错误即将起作用update_info()
您那里没有“try {”
