Handling financial transactions in a Laravel/PHP application demands accuracy, security, and adherence to best practices to ensure reliable monetary processing. Whether you’re building an e-commerce site, an invoicing system, or any application dealing with payments, following these best practices will help you manage money effectively in Laravel and PHP.
1. Choose the Right Data Type for Money
A common mistake in financial handling is using floating-point numbers (float or double), which can lead to rounding errors. Instead, use integers (e.g., storing amounts in cents) or decimal types in the database.
Recommended approach:
- Use integers (store amounts in cents rather than dollars).
- Alternatively, use
DECIMAL(10,2)in MySQL for fixed-point accuracy.
2. Leverage Laravel’s Money Handling Libraries
Instead of handling money calculations manually, utilize libraries like brick/money or moneyphp/money, which provide robust functions for financial operations.

To avoid ambiguity, always store and process transactions with a specific currency code (USD, EUR, etc.).

5. Validate and Sanitize Input Data
Ensure that monetary inputs are validated and sanitized to prevent errors or security risks.
