How does the modulus operator in PHP help in determining the shift number in a repeating cycle?

The modulus operator in PHP helps in determining the shift number in a repeating cycle by calculating the remainder of a division operation. In a repeating cycle, we can use the modulus operator to wrap around the shift number once it reaches the end of the cycle, ensuring it stays within the bounds of the cycle. 

$shiftNumber = 10; // original shift number
$cycleLength = 5; // length of the repeating cycle

$newShiftNumber = $shiftNumber % $cycleLength; // calculate the new shift number within the cycle

echo "Original Shift Number: " . $shiftNumber . "\n";
echo "New Shift Number within Cycle: " . $newShiftNumber;
