What are best practices for handling large numbers in PHP calculations to avoid precision errors?

When dealing with large numbers in PHP calculations, it is recommended to use the BCMath extension, which provides arbitrary precision math functions. By using BCMath functions like `bcadd`, `bcsub`, `bcmul`, and `bcdiv`, you can perform calculations on large numbers without encountering precision errors. 

// Example of using BCMath functions to perform calculations on large numbers
$number1 = '123456789012345678901234567890';
$number2 = '987654321098765432109876543210';

$result = bcadd($number1, $number2); // Addition
echo $result . "\n";

$result = bcsub($number1, $number2); // Subtraction
echo $result . "\n";

$result = bcmul($number1, $number2); // Multiplication
echo $result . "\n";

$result = bcdiv($number1, $number2); // Division
echo $result . "\n";
