What potential issues can arise with PHP calculations when the result is 0?

When performing calculations in PHP, dividing by zero can result in a warning or error. To avoid this issue, you can check if the divisor is zero before performing the division operation. If the divisor is zero, you can handle it by returning a default value or displaying an error message. 

$dividend = 10;
$divisor = 0;

if ($divisor != 0) {
    $result = $dividend / $divisor;
} else {
    $result = "Cannot divide by zero";
}

echo $result;
