A simple example of using RuntimeException Class:-

Lets say we would be dividing two numbers and throw an exception as soon as the denominator is equal to zero.

= 10;
$iNum2 = 0;

if (
$iNum2 == 0){
throw new
RuntimeException("Division by Zero");
$iResult = $iNum1 / $iNum2;
echo (
"Division Result of \$iNum1 and $iNum2 = ".($iResult)."<br/>");
catch (
RuntimeException $e){
echo (
"Division by Zero is not possible");
