What are the best practices for efficiently performing bitwise operations in PHP without GMP extension?

Performing bitwise operations in PHP without the GMP extension can be less efficient due to the limitations of PHP's built-in integer size. One way to overcome this is by using the bcmath extension, which allows for arbitrary precision arithmetic operations. By converting the integers to strings and using the bcmath functions, we can efficiently perform bitwise operations in PHP. 

$a = "12345678901234567890";
$b = "98765432109876543210";

$bitwise_and = bcmul($a, $b);
$bitwise_or = bcadd($a, $b);
$bitwise_xor = bcsub(bcadd($a, $b), bcmul($a, $b));

echo "Bitwise AND: " . $bitwise_and . "\n";
echo "Bitwise OR: " . $bitwise_or . "\n";
echo "Bitwise XOR: " . $bitwise_xor . "\n";
