Are there best practices for efficiently checking if a specific option is included in a bitwise sum in PHP?

When dealing with bitwise operations in PHP, it can be efficient to check if a specific option is included in a bitwise sum by using the bitwise AND operator (&). This operator allows you to test if a specific bit is set in the sum by performing a bitwise AND operation between the sum and the option you want to check. If the result is greater than zero, then the option is included in the sum. 

$sum = 6; // Binary: 110
$option = 2; // Binary: 010

if ($sum & $option) {
    echo "Option is included in the sum";
} else {
    echo "Option is not included in the sum";
}
