php adding 1 hour to the timestamp

Question

I am trying to add 1 hour to a timestamp field fetched from database using the following code.

date($ls['created_at'], strtotime('+1 hour'));

However, this doesn't seem to work. It returns the same time as in database. Am I missing something? Or, is the code deprecated? What is the proper solution?

You need to give it the correct syntax to use this, You need to send the time to change with the change itself in the function - for example (using date for wanted format):

$date = "22-02-2021 14:22:22";
echo date("d-m-Y H:i:s", strtotime($date.' +1 hour'));

This will return:

22-02-2021 15:22:22

Same as this:

echo date("d-m-Y H:i:s", strtotime("22-02-2021 14:22:22 + 1 hour"));

The idea is that you strtotime receives the date and data to change in one string like this :

echo strtotime("22-02-2021 14:22:22 + 2 hour");

Will return:

1614010942

Here I removed the Date Format so I received a unix timestamp format
