What best practices should be followed when storing calculated data from Excel in a database using PHP?

When storing calculated data from Excel in a database using PHP, it is important to sanitize the data to prevent SQL injection attacks. Additionally, it is recommended to use prepared statements to securely insert the data into the database. Lastly, consider validating the data before storing it to ensure accuracy and consistency. 

// Assuming $calculatedData is an array containing the calculated data from Excel

// Establish a database connection
$pdo = new PDO('mysql:host=localhost;dbname=your_database', 'username', 'password');

// Prepare the SQL statement
$stmt = $pdo->prepare("INSERT INTO your_table (column1, column2) VALUES (:value1, :value2)");

// Loop through the calculated data and insert into the database
foreach($calculatedData as $data) {
    $stmt->bindParam(':value1', $data['value1']);
    $stmt->bindParam(':value2', $data['value2']);
    $stmt->execute();
}

// Close the database connection
$pdo = null;
