What is the purpose of using the % operator in PHP and how does it affect loop iterations?

The % operator in PHP is used to calculate the remainder of a division operation. It is often used in loops to perform actions based on whether the current iteration is even or odd. By using the % operator, you can easily check if a number is divisible by another number, allowing for conditional logic within loop iterations. 

// Example of using the % operator in a loop
for ($i = 1; $i <= 10; $i++) {
    if ($i % 2 == 0) {
        echo "$i is even<br>";
    } else {
        echo "$i is odd<br>";
    }
}
