Exemple d'utilisation de bind_result vs get

Le facteur décisif pour moi est de savoir si j'appelle mes colonnes de requête en utilisant * .

Utiliser `bind_result()` serait mieux pour ça :

// Use bind_result() with fetch()
$query1 = 'SELECT id, first_name, last_name, username FROM table WHERE id = ?';

Utiliser `get_result()` serait mieux pour ça :

// Use get_result() with fetch_assoc() 
$query2 = 'SELECT * FROM table WHERE id = ?';

Exemple 1 pour `$query1` en utilisant `bind_result()`

$query1 = 'SELECT id, first_name, last_name, username FROM table WHERE id = ?';
$id = 5;

if($stmt = $mysqli->prepare($query)){
   /*
        Binds variables to prepared statement

        i    corresponding variable has type integer
        d    corresponding variable has type double
        s    corresponding variable has type string
        b    corresponding variable is a blob and will be sent in packets
   */
   $stmt->bind_param('i',$id);

   /* execute query */
   $stmt->execute();

   /* Store the result (to get properties) */
   $stmt->store_result();

   /* Get the number of rows */
   $num_of_rows = $stmt->num_rows;

   /* Bind the result to variables */
   $stmt->bind_result($id, $first_name, $last_name, $username);

   while ($stmt->fetch()) {
        echo 'ID: '.$id.'<br>';
        echo 'First Name: '.$first_name.'<br>';
        echo 'Last Name: '.$last_name.'<br>';
        echo 'Username: '.$username.'<br><br>';
   }

   /* free results */
   $stmt->free_result();

   /* close statement */
   $stmt->close();
}

/* close connection */
$mysqli->close();

Exemple 2 pour `$query2` en utilisant `get_result()`

$query2 = 'SELECT * FROM table WHERE id = ?'; 
$id = 5;

if($stmt = $mysqli->prepare($query)){
   /*
        Binds variables to prepared statement

        i    corresponding variable has type integer
        d    corresponding variable has type double
        s    corresponding variable has type string
        b    corresponding variable is a blob and will be sent in packets
   */
   $stmt->bind_param('i',$id);

   /* execute query */
   $stmt->execute();

   /* Get the result */
   $result = $stmt->get_result();

   /* Get the number of rows */
   $num_of_rows = $result->num_rows;



   while ($row = $result->fetch_assoc()) {
        echo 'ID: '.$row['id'].'<br>';
        echo 'First Name: '.$row['first_name'].'<br>';
        echo 'Last Name: '.$row['last_name'].'<br>';
        echo 'Username: '.$row['username'].'<br><br>';
   }

   /* free results */
   $stmt->free_result();

   /* close statement */
   $stmt->close();
}

/* close connection */
$mysqli->close();

Comme vous pouvez le voir, vous ne pouvez pas utiliser bind_result avec * . Cependant, get_result fonctionne pour les deux, mais bind_result est plus simple et supprime une partie du désordre avec $row['name'] .
