PHP - Will uniqid() generate alphabetical IDs?

Question

If I use the PHP uniqid() function to generate IDs, and then I sort the IDs alphabetically in MySQL, will they be in the same order they were created?

It seems to me like they should be, since the IDs are just incrementing hexadecimal characters (at least I think they are), but does anyone know for certain?

Answer 1

The uniqid() function generates a unique ID based on the microtime (current time in microseconds).

So I would probably say yes.
