Creating DivideByZeroException Class

Here, we will create a user-defined class DivideByZeroException that inherits the Exception class to handle the divide by zero situation using the PHP program.

PHP code to create DivideByZeroException class

The source code to create DivideByZeroException class using exception handling is given below. The given program is compiled and executed successfully.

<?php

{
}

try
{
    $A = 10;
    $B = 0;

    if ($B == 0) throw new DivideByZeroException("Divide by Zero exception");
    $C = $A / $B;
    printf("Value of C: %d<br>", $C);
}
catch(DivideByZeroException $e)
{
    printf("Exception: %s", $e->getMessage());
}
?>

Output

Exception: Divide by Zero exception

Explanation

Here, we created a class DivideByZeroException that inherits the predefined class Exception. Here, we created two local variables $A, $B that are initialized with 10 and 0 respectively.

if($B==0)
    throw new DivideByZeroException ("Divide by Zero exception");

Here, we check the condition, if the value of $B is 0 then it will throw an exception using the throw keyword that will be caught by catch block and print specified message on the webpage.
