Check Even and ODD in PHP

Right now, we are going to check whether a given number is an EVEN number of an ODD number.

Given a number and we need to check whether it is an EVEN number of an ODD number utilizing PHP Code.

Indeed, even numbers are the numbers which are separable by 2, similar to 2, 4, 6, 8, 10, and so on, and the ODD numbers are not detachable by 2, similar to 3, 5,7, 9, 1 and so forth

Example:

    Input: 12
    Output: 12 is an EVEN number
    12 is divisible by 2, it returns remainder 0

    Input: 13
    Output: 13 is an ODD number
    13 is not divisible by 2, because it returns remainder 1

PHP code to check it:

<?php
   //program to check EVEN or ODD
   //function: isEvenOrOdd
   //description: This function will check
   //whether a given number is EVEN or ODD
   function isEvenOrOdd($num){
        //if num is divisible by 2 than
        //it will be an EVEN number or it 
        //will be an ODD number
        if( $num % 2 == 0)
            return 1; //will check as EVEN number
        else
            return 0; //will check as ODD number
   }
   
   //main code to test the function
   $number = 12;
   if(isEvenOrODD($number))
        print_r($number." is EVEN number");
   else
        print_r($number." is ODD number");

    print_r("\n");
    
    //again check with an ODD number
   $number = 13;
   if(isEvenOrODD($number))
        print_r($number." is EVEN number");
   else
        print_r($number." is ODD number");    
?>

Output

12 is EVEN number
13 is ODD number
