In PHP, what are the considerations for maintaining data integrity when dealing with large numbers that exceed the limits of standard int data types?

When dealing with large numbers that exceed the limits of standard int data types in PHP, consider using the BCMath extension. This extension provides arbitrary precision mathematics functions that can handle large numbers without losing data integrity. By using BCMath functions like bcmath_add() and bcmath_mul(), you can perform calculations on large numbers accurately. 

$largeNumber1 = '123456789012345678901234567890';
$largeNumber2 = '987654321098765432109876543210';

$result = bcmul($largeNumber1, $largeNumber2);

echo $result;
