How can beginners in PHP improve their understanding of arithmetic operators like modulo for checking even and odd numbers?

Beginners in PHP can improve their understanding of arithmetic operators like modulo for checking even and odd numbers by practicing with simple examples. They can create a function that takes a number as input and uses the modulo operator (%) to check if the number is even or odd. By experimenting with different numbers and observing the results, beginners can solidify their understanding of how the modulo operator works in PHP. 

function checkEvenOdd($number) {
    if($number % 2 == 0) {
        echo $number . " is even.";
    } else {
        echo $number . " is odd.";
    }
}

// Test the function with different numbers
checkEvenOdd(5); // Output: 5 is odd.
checkEvenOdd(10); // Output: 10 is even.
