How to upload a file with a different file name

I have a file input known as 'name=fileImage'. Now I have php code below where it checks to see if file exists in the folder (ImageFiles) or not:

if (file_exists("ImageFiles/" . $_FILES["fileImage"]["name"]))
  {

  }

My question is that if a file does exist in the folder, how can it be coded so that it still uploads the file but it gives it a different file name. Maybe something like automatically add a number at the end of the filename to give it a different file name?

If you want to rename the uploaded file to a name of your own choice, you can try 

<?php

    //Any file name user/uploader has chosen/used on his/her computer
    $tmp_name = $_FILES["domainfile"]["tmp_name"];

    //Name you want
    $name = "MyDesiredName.png"; //save as MyDesiredName.png

    //Move/save file
    move_uploaded_file($tmp_name, $name);

?>

Obviously this code will replace the old file everytime a new file gets uploaded.
To not to let this happen, you need to introduce some variable in the $name
and do $name++ and to find a way to store its value for future reference.

$_FILES is just a variable, that happens to be superglobal and pre-populated with file upload data. Meaning you can easily change it.

For example:

if( file_exists("ImageFiles/".$_FILES['fileImage']['name'])) {
    $parts = explode(".",$_FILES['fileImage']['name']);
    $ext = array_pop($parts);
    $base = implode(".",$parts);
    $n = 2;
    while( file_exists("ImageFiles/".$base."_".$n.".".$ext)) $n++;
    $_FILES['fileImage']['name'] = $base."_".$n.".".$ext;
}
// now use $_FILES['fileImage']['name'] just like you would normally
