What is the recommended approach for handling large numbers in PHP without losing precision?

When dealing with large numbers in PHP, the recommended approach is to use the BCMath extension, which provides arbitrary precision arithmetic functions. This extension allows you to perform calculations on numbers with arbitrary precision, ensuring that you do not lose precision when working with large numbers. 

// Example of using BCMath extension to handle large numbers without losing precision
$number1 = '123456789012345678901234567890';
$number2 = '987654321098765432109876543210';

$result = bcadd($number1, $number2); // Addition
echo $result;
