Are there any best practices for handling decimal numbers in PHP to avoid errors?

When working with decimal numbers in PHP, it's important to be mindful of potential floating-point precision errors. To avoid these errors, it's recommended to use the BCMath extension, which provides arbitrary precision arithmetic functions for working with decimal numbers in PHP. 

// Using BCMath extension for handling decimal numbers in PHP

$number1 = '1.234';
$number2 = '5.678';

$sum = bcadd($number1, $number2, 3); // Adding two decimal numbers with precision of 3

echo $sum; // Output: 6.912
