Just give the files a name based on a "Universally Unique Identifier".
http://en.wikipedia.org/wiki/UUID

OK, you /could/ get a clash of names, but this is a) very unlikely and
b) simple to check for.

There is a PECL module for PHP to generate these:
http://pecl.php.net/package/uuid (new version just a couple days ago
after a 4 year gap.... if that's not a sign I don't know what is!).

If you can't install the PECL module, but do have a MySQL server to hand
you can abuse it by doing:

mysql> SELECT UUID();
+--------------------------------------+
| UUID()                               |
+--------------------------------------+
| 14255808-4dbb-102b-a371-0015c5bd762d |
+--------------------------------------+
