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.



<?php

$iNum1 = 10;

$iNum2 = 0;



try{

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");

}

?>
