How can PHP developers prevent division by zero errors in their code, especially when working with user input?

Division by zero errors can be prevented by checking if the divisor is zero before performing the division operation. This can be done by adding a simple conditional statement to verify the divisor value before executing the division operation.

$dividend = 10;
$divisor = 0;

if ($divisor != 0) {
    $result = $dividend / $divisor;
    echo "Result: " . $result;
} else {
    echo "Division by zero error!";
}
