inattendu T_CATCH, attendez T_FUNCTION

Question

Aujourd'hui, en essayant d'écrire cette classe User, j'ai rencontré l'erreur ci-dessus sur la ligne en surbrillance ci-dessous, et je me demandais ce que vous en pensiez.

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; 
    } 
}

Answer 2

code corrigé: Essayez maintenant:

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() 
    { 
     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["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; 
    } 
} 

Il avait le problème où Essayer a commencé à partir d'une fonction et se termine sur une autre.

Et vous devriez indenter correctement votre code. Les bogues deviendront clairs automagiquement.

Answer 3

Votre construction construct accolades {} ne se ferme pas correctement et vous avez du code en dehors d'une fonction.
