20 Number is Even
<?php
$check=20;

Here we use ternary operator , Firstly we know about its syntax
condition ? true: false
Here our condition is $check%2==0 , means if we divide $check with 2 then remainder is 0; if its true than we write Number is Even after ? symbol, Else we write Number is Odd after : symbol

/* Here is Our Variable named x, in which we store a value, We provide int value only(without decimal point) when we echo $x%2, then iyt will return a value that is 0 or 1, Depend on what remainder is, when we divide variable value by 2
so we write it in switch, & it will match it with case value.
