Online Storage App - Deleting Files

<?php $name=$_GET['name'];
$target = "../upload/$name"; 
$myFile = $target;

This is a piece of code that i have used once before. In this case i have got the file name after it was posted to the url. The unlink part is the bit where it deletes the file.

Make sure you use proper security. In this case the user could potentially change the url from .php?name=file1 to .php?name=file2 and therefore delete file2 aswell.
