Are there any best practices for handling currency values in PHP?

When handling currency values in PHP, it is important to use the appropriate data type and functions to ensure precision and accuracy. The most commonly recommended data type for handling currency values is the `float` data type. Additionally, using number formatting functions such as `number_format()` can help display currency values in a user-friendly format with proper decimal places and thousands separators.

// Example of handling currency values in PHP
$amount = 1234.56;
$formatted_amount = number_format($amount, 2); // Output: 1,234.56

echo "Total amount: $" . $formatted_amount;
