There are a few things...
1.- read() reads the directory as an iterator, returning the file name, have you tried to echo $file; ?
if($file >= 1) will never be true, as $file is always a String, never an integer, you are comparing there: if("myfilename.ext" >= 1).
To count the total files you should do a while through the full directory and use a counter, increasing it for each file.
Or you can use scandir("myPath") function, that get all the files in the path specified as an array. for example:
$dir = scandir("myDir");
$total = count($dir); // this gives you the lenght of the array, therefore the files.
While counting, remember that the parent, and root directory are counted as "files" as well, and with some methods also the thumbs.db(windows) or DS_store(osx) are hidden files that store information about how you sort the folder, folder icons and stuff, will be counted as well, so remember to add an If statement to skip them.
