"The modulo by zero error" throws when we divide a number by zero to get the remainder using modulus operator (%).

It can be handled by using "try...catch" statement, with DivisionByZeroError exception.

Example:

<?php
    $a = 10;
    $b = 3;
    
    try 
    {
        //dividing $a by $b - no error 
        $result = $a%$b;
        print("result: $result \n");
        
        //assigning 0 to $b
        $b = 0;

        //now, dividing $a by $b - error occurs
        $result = $a%$b;
        print("result: $result \n");        
    }
    catch(DivisionByZeroError $err){
        print("Exception... ");
        print($err->getMessage());
    }
