What are the potential pitfalls of using mysqli_stmt::get_result in PHP, especially in older versions like PHP 5.3?

The potential pitfall of using mysqli_stmt::get_result in PHP, especially in older versions like PHP 5.3, is that this method is only available in PHP versions 5.3.0 and above, and requires the mysqlnd driver. If you are using an older version of PHP or do not have the mysqlnd driver installed, this method will not work. To solve this issue, you can fetch the results manually using mysqli_stmt::bind_result and mysqli_stmt::fetch. 

// Check if mysqli_stmt::get_result is available
if (function_exists('mysqli_stmt_get_result')) {
    $result = $stmt->get_result();
    
    // Fetch data from result
    while ($row = $result->fetch_assoc()) {
        // Process each row
    }
} else {
    // Manually bind result variables and fetch
    $stmt->bind_result($col1, $col2);
    
    while ($stmt->fetch()) {
        // Process each row
    }
}
