How can binary operators be utilized in PHP to determine if a variable is odd?

To determine if a variable is odd in PHP, we can use the bitwise AND operator (&) with 1. If the result is 1, then the number is odd. If the result is 0, then the number is even. 

$number = 5;

if ($number & 1) {
    echo "The number is odd.";
} else {
    echo "The number is even.";
}
