What potential pitfalls can arise when trying to manipulate large numbers in PHP?

When manipulating large numbers in PHP, potential pitfalls can arise due to integer overflow or precision loss when dealing with extremely large or small numbers. To avoid these issues, it is recommended to use the BCMath extension in PHP, which provides arbitrary precision mathematics functions for working with numbers of any size. 

// Example of using BCMath extension to perform arithmetic operations with large numbers
$largeNumber1 = '123456789012345678901234567890';
$largeNumber2 = '987654321098765432109876543210';

$result = bcadd($largeNumber1, $largeNumber2); // Addition
echo $result; // Output: 111111111011111111101111111110
