How can PHP developers handle the risk of division by zero when evaluating mathematical expressions?

To handle the risk of division by zero when evaluating mathematical expressions in PHP, developers can check if the divisor is zero before performing the division operation. This can be done using an if statement to prevent the division by zero error. 

$dividend = 10;
$divisor = 0;

if ($divisor != 0) {
    $result = $dividend / $divisor;
    echo "Result: " . $result;
} else {
    echo "Error: Division by zero is not allowed.";
}
