Just like you stored it. You made the database.

If you want do do the calculation you need to store all involved values within the DOM, e.g. in input-elements with a unique ID. Then you can get these values with document.getElementById(<yourID>), just have a look at the manual https://developer.mozilla.org/en-US/docs/Web/API/Document/getElementById

at a minimum <div class="carousel-item active"> <?=$row[0]?> <?=$row[1]?> <?=$row[2]?> <?=$row[3]?> </div>

Your post lacks relevant information what should this mean to anyone? What error messages did you get? What is the actual and the expected behavior? Your code is incomplete, you did not say which return values you got or what you tested against.

so what's the expected behavior? Where is the test case?

And what's not working? Input? Output? Expected behavior? Create a test case.

As you have no `eval()` in your code, this message comes from somewhere else. That's not the handler.php you are showing.

You can use window.navigator.geolocation.watchPosition or try getCurrentPosition with setInterval()
