What are some common challenges faced by PHP beginners when trying to create mathematical functions within PHP code?

One common challenge faced by PHP beginners when creating mathematical functions is handling data types correctly. PHP is a loosely typed language, so ensuring that variables are of the correct type before performing mathematical operations is crucial. Another challenge is managing errors such as division by zero or invalid input values. Proper error handling and validation can help prevent unexpected results or crashes in mathematical functions. 

function divide($numerator, $denominator) {
    if ($denominator == 0) {
        throw new Exception("Division by zero error");
    }
    
    if (!is_numeric($numerator) || !is_numeric($denominator)) {
        throw new Exception("Invalid input values");
    }
    
    return $numerator / $denominator;
}
