    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");
    }
    ?>
