Integer in while loop wont increase value - php

Question

I'm having a problem in my code, I am trying to append a number to a filename if filename already exists. It goes something like this
$explode = explode(".", $fileName);
$extension = end($explode);
$fileactualname = reset($explode);
$i = 0;
while (file_exists($location.$fileName)) {
$i++;
}
$fileName= $i.$fileName;
$name = $fileName;
$moveResult = move_uploaded_file($fileTmpLoc, $location . "/". $name);
if ($moveResult != true) {
#unlink($fileTmpLoc);
header('location: ' . URL . '?page=0&sort=name&type=desc&folder=uploads/&message=uploaderror');
}
Unfortunately for some reason $i wont increase its value by 1 every time it loops, instead it adds to the filename this way 1234filename.jpg my file name variable is after the loop and i cant understand why this is accruing. I am expecting to get ($i)filename.jpg a single number
AFTER RESTARTING MY LOCALSERVER IT STARTED WORKING WITH THE CODE PROVIDED BELOW DUUUH

You need to use the actual filename when you concat the number to it and not the one you already added a number to.
// not sure why you are splitting the filname up here
$explode = explode(".", $fileName);
$extension = end($explode);
$fileactualname = reset($explode);
$i = 0;
$fn = $fileName;
while (file_exists($location.$fn)) {
$i++;
// add number to actual filename
$fn = $i.$fileName;
}
$name = $fn;
$moveResult = move_uploaded_file($fileTmpLoc, $location . "/". $name);
