How can PHP developers ensure that numerical inputs are correctly formatted and saved in a database to avoid data inconsistencies?

To ensure that numerical inputs are correctly formatted and saved in a database to avoid data inconsistencies, PHP developers can use functions like `intval()` or `floatval()` to convert the input to the appropriate numeric data type before saving it to the database. Additionally, developers can use prepared statements or parameterized queries to prevent SQL injection attacks and ensure that the data is saved securely. 

// Assuming $input contains the numerical input from the user
$numeric_input = intval($input); // Convert input to integer

// Use prepared statements to save the data securely in the database
$stmt = $pdo->prepare("INSERT INTO table_name (numeric_column) VALUES (:numeric_input)");
$stmt->bindParam(':numeric_input', $numeric_input);
$stmt->execute();
