What are the different ways to store currency values in a PHP database?

When storing currency values in a PHP database, it is important to use the appropriate data type to ensure accuracy and consistency. One common way to store currency values is to use the DECIMAL data type with a specified precision and scale to represent the amount in the database. This helps to maintain the correct number of decimal places and prevent rounding errors. 

// Example of storing currency values in a PHP database using DECIMAL data type
$amount = 123.45; // Currency value to be stored

// Connect to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Prepare SQL statement to insert currency value into database
$sql = "INSERT INTO currency_table (amount) VALUES (?)";
$stmt = $conn->prepare($sql);
$stmt->bind_param("d", $amount); // 'd' is for DECIMAL data type
$stmt->execute();

// Close statement and connection
$stmt->close();
$conn->close();
