What is the purpose of using bitwise operators in PHP, and what are some potential applications for them?

Bitwise operators in PHP are used to manipulate individual bits of an integer. They are often used in scenarios where you need to perform operations at the binary level, such as setting or unsetting specific bits, checking if a bit is set, or performing bitwise operations like AND, OR, XOR, and NOT. Example: 

// Using bitwise operators to check if a specific bit is set
$number = 5; // 101 in binary
$bitToCheck = 2; // Check if the 2nd bit is set

if ($number & (1 << $bitToCheck)) {
    echo "The {$bitToCheck}nd bit is set";
} else {
    echo "The {$bitToCheck}nd bit is not set";
}
