How can the MySQL queries in the provided script be optimized for better performance and accuracy?

The MySQL queries in the provided script can be optimized for better performance and accuracy by using prepared statements to prevent SQL injection attacks and improve query execution. Prepared statements separate the SQL query logic from the data being passed into the query, which can help improve performance and ensure data integrity. 

// Create a prepared statement for the SELECT query
$stmt = $mysqli->prepare("SELECT name, age FROM users WHERE id = ?");
$stmt->bind_param("i", $id);

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

// Bind the result variables
$stmt->bind_result($name, $age);

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

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