What are the potential pitfalls of using MySQLi_STMT::store_result() in PHP when working with prepared statements?

Using MySQLi_STMT::store_result() can potentially lead to performance issues if dealing with large result sets, as it fetches the entire result set into memory. To avoid this, it is recommended to bind the result set directly to variables using MySQLi_STMT::bind_result() instead. 

// Prepare the statement
$stmt = $mysqli->prepare("SELECT id, name FROM users WHERE id = ?");
$stmt->bind_param("i", $id);

// Execute the statement
$stmt->execute();

// Bind the result set directly to variables
$stmt->bind_result($userId, $userName);

// Fetch the result
$stmt->fetch();

// Use the variables as needed
echo "User ID: " . $userId . ", User Name: " . $userName;

// Close the statement
$stmt->close();
