Can't make a script that checks the current date on the server and adds +2 days to the number in the tag?

Question

PHP

I am learning js. I want to write a simple script that checks the current date on the server and adds +2 days to today's number, and then outputs the result to span.
for example,
today is September 9th, the script looks at today's date, then adds +2 days and outputs the result to span.

<p>До <span id="data">11</span> сентября получите подарок.</p>

how to do it more gracefully

Answer 1

In a loop, we check the following. array element to zero if true then continue counting
foreach | for -> if array_key_exists($key+1, $arr) and $arr[$key+1] ==0

Answer 2

JS in the browser has no idea what time it is on the server. You can use a server script to set the server time on the page.

var serverTimestamp = <?php echo time();?> // или какой там у вас серверный язык
var serverDate = new Date(serverTimestamp)
var day = serverDate.getDay()

It remains to add a deuce and bring it to span

document.getElementById('data').innerHTML = day + 2;

Answer 3

var today = new Date();
var then = new Date(today.getTime() + 2*60*60*24*1000);
document.getElementById('data').innerText = then.getDate();
