How can integer overflow be prevented or managed in PHP?

Integer overflow can be prevented or managed in PHP by using the `bcmath` extension, which allows for arbitrary precision arithmetic. By using functions like `bcadd()`, `bcsub()`, `bcmul()`, and `bcdiv()`, you can perform calculations on large numbers without the risk of integer overflow. 

// Preventing integer overflow using the bcmath extension
$a = "9223372036854775807"; // Maximum value for a 64-bit signed integer
$b = "1";
$result = bcadd($a, $b);
echo $result; // Output: 9223372036854775808
