Create Unique Image Names

Question

What\'s a good way to create a unique name for an image that my user is uploading?

I don\'t want to have any duplicates so something like MD5($filename) isn\'t suita

http://php.net/manual/en/function.uniqid.php maybe?

• You can prefix it with the user id to avoid collisions between 2 users (in less than one millisecond).
