Answer 1

Use DateTime::diff() function

The DateTime::diff() function is an inbuilt function in PHP which is used to return the difference between two given DateTime objects.

<?php

// Initialising the two datetime objects 

$datetime1 = new DateTime('2019-9-10'); 
$datetime2 = new DateTime('2019-9-15'); 

// Calling the diff() function on above 
$difference = $datetime1->diff($datetime2); 

// Getting the difference between two 
echo $difference->format('%R%a days'); 

?>

Answer 2

Just do

if($fromDate == $toDate){
    $diffdays = 0;
}

I don't know if this is what you want. But basically add a condition to see if they are the same, and add the value you want. I added 0 since I think that's what the difference should be.
