What are the best practices for handling decimal numbers with precision in PHP when interacting with a MySQL database?

When handling decimal numbers with precision in PHP when interacting with a MySQL database, it is important to use the appropriate data types in both PHP and MySQL to avoid rounding errors or loss of precision. In PHP, you can use the `float` data type to represent decimal numbers with floating-point precision. In MySQL, you can use the `DECIMAL` data type to store decimal numbers with fixed-point precision. 

// Example PHP code snippet for handling decimal numbers with precision in MySQL
$mysqli = new mysqli("localhost", "username", "password", "database");

// Define a decimal number with precision
$decimalNumber = 123.456789;

// Prepare a SQL statement with a placeholder for the decimal number
$stmt = $mysqli->prepare("INSERT INTO table_name (decimal_column) VALUES (?)");
$stmt->bind_param("d", $decimalNumber);

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

// Close the statement and database connection
$stmt->close();
$mysqli->close();
