Hi,
Pretty soon I'm going to be needing to generate a unique identifier in a
script. I'm looking into how to go about doing it now.
It has to work on Apache 2 / PHP 5.0.4 (Module) / Windows 2000 Server.
Any suggestions on how I might be able to do it?
I've noticed the uuid PECL package,

I was given a database that has uniques IDs such as:
AL1
AL2
AR1
AR2
MI1
etc...
The first two letters are based on the state they live
in, then it would need to look at the next 5
characters to determine the next ID.
My problem is how do I recreate this in PHP to make
sure

Any ideas? Thank you in advance!
does it all have to be in the same field? can you not just combine two
fields?
one field would be called 'id' and it would be auto-incrementing.
second field would be 'state' and it
I'd like to keep it in one field if possible since
that's how their database is now and data will be
going back and forth.
Plus there should be allowed two of the same numbers,
so like:
AL3
KY3
So any state with more than one record can be
sequential and not jump around like KY3,

Will it be able to figure out what the last number is
if it's a character type and the number is something

something like 10003.

Yeah thanks for the feedback, I'm already including a
primary key auto_increment field in place to tie the
tables together with an ID I *know* will be unique.
This other ID scheme is just to work within their
existing system that uses this. I'm just trying to
mirror/maintain that scheme for

I haven't played much with these functions but I think for MySQL you'd
want something like this, for the state XX (excuse the wrapped
lines):

Wow I think you are on to something!!! I'll give it a

Hi folks,
I'm using usual md5(microtime()); to create IDs, but now I've encountered a
problem with that. I need to create explicitly 6 digit unique
number(decimal). Yes, I know I can use for/while loop to fill a string with
digits, but is it ABSOLUTELY sure that the random will never return same

MySQL (or another SQL database) is the answer. You can check for an
existing OR use it's auto_increment or whatever else you like.
Create a field to track all this stuff. There is no other way to
guarantee that an ID is unique than to check it against existing.
Random functions yield random

Neither auto-increment nor sequences allow you to do what you're asking for
though, which is like database garbage collection. If you really need
something like this you should implement it in a cron job that runs during
non-peak hours as it will be quite an expensive
