How do bitwise operations in PHP compare to other programming languages in terms of performance and efficiency?

Bitwise operations in PHP are generally efficient and perform well compared to other programming languages. However, the performance may vary depending on the specific operation and the size of the data being manipulated. It is important to use bitwise operations judiciously and consider the impact on readability and maintainability of the code. 

// Example of using bitwise operations in PHP
$num1 = 10; // 1010 in binary
$num2 = 6; // 0110 in binary

// Bitwise AND
$result_and = $num1 & $num2; // Result: 2 (0010 in binary)

// Bitwise OR
$result_or = $num1 | $num2; // Result: 14 (1110 in binary)

// Bitwise XOR
$result_xor = $num1 ^ $num2; // Result: 12 (1100 in binary)

// Bitwise NOT
$result_not = ~$num1; // Result: -11 (11111111111111111111111111110101 in binary)

echo $result_and . "\n";
echo $result_or . "\n";
echo $result_xor . "\n";
echo $result_not . "\n";
