What alternative approaches can be taken to avoid rounding errors and inaccuracies when dealing with monetary values in PHP?

When dealing with monetary values in PHP, it is important to avoid rounding errors and inaccuracies that can occur due to floating-point arithmetic. One approach to address this issue is to use the BCMath extension in PHP, which provides arbitrary precision arithmetic functions for working with numbers. By using BCMath functions such as `bcadd()`, `bcsub()`, `bcmul()`, and `bcdiv()` instead of regular arithmetic operators, you can perform accurate calculations with monetary values. 

// Example of using BCMath extension for precise monetary calculations
$price1 = '10.25';
$price2 = '5.75';

// Add two prices
$total = bcadd($price1, $price2, 2);

echo $total; // Output: 16.00
