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");
}
?>
Direct known subclasses (following the java docs convention (: ): OutOfBoundsException, OverflowException, RangeException, UnderflowException, UnexpectedValueException
