Submitted by Nidhi, on November 22, 2020

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.

Program/Source Code:

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

<?php
// PHP program to create DivideByZeroException class.
class DivideByZeroException extends Exception
{
}

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.
