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

  $fileName= $i.$fileName; should be inside the while loop.

  The problem is not with $i, but with $fileName: you change it each iteration, and keep appending numbers to it

  You've completely ignored the main points people are telling you. Just use Riggs' code.

  Just reread Riggs answer. Slowly, line by line, taking care with where the variable names change. Your solution is right there.

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);
