Interesting thought. My idea on this is to use the approach used when
replicating a DB. It is similar to the namespace idea if not the same:
Say you have 3 databases, you could use mod 3 numbers for A=0, B=1 and C=2
So on A you would have 0, 3, 6, 9, ... on B 1, 4, 7, 10,

Here's part of the confusion:
If you were to express the number of microseconds since 1970 in a
decimal number, it would indeed take 16 digits.
But uniqid() returns a /13 character string/, not a 13 digit number. The
string is actually a hexadecimal number (and thus can express a greater
range o

Hi all. I'm sure I can't be the first person to ask this question but a search
of the net leaves me confused.
I need a unique identifier in an SQL table and for complicated reasons I don't
want to use auto-increment.
So I thought I would use a pseudo-random method instead. I am NOT scared of
