Are there any common misconceptions about using the Modulo operator in PHP?

One common misconception about using the Modulo operator in PHP is that it always returns a positive result. However, when dealing with negative numbers, the Modulo operator can return a negative result. To ensure a positive result, you can add the divisor to the negative number before applying the Modulo operator. 

// Incorrect usage of Modulo operator with negative numbers
$number = -5;
$divisor = 3;
$result = $number % $divisor; // This can return a negative result

// Correct way to handle Modulo operator with negative numbers
$number = -5;
$divisor = 3;
$result = ($number % $divisor + $divisor) % $divisor; // This will always return a positive result
