What are common issues with PHP when handling large numbers and how can they be resolved?

Issue: PHP may encounter precision errors when handling large numbers due to its default floating-point precision settings. This can result in inaccurate calculations or unexpected behavior when dealing with large numerical values. Solution: To handle large numbers accurately in PHP, you can use the BCMath extension, which provides arbitrary precision mathematics functions for working with numbers of any size. 

// Using BCMath extension for arbitrary precision math
$number1 = '123456789012345678901234567890';
$number2 = '987654321098765432109876543210';

$sum = bcadd($number1, $number2);
echo $sum;
