RE: [PHP] Unique ID system - need help/ideas

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 their

Will it be able to figure out what the last number is if it's a character type and the number is something like 3? So it'll add one to make it 4 and not something like 10003. ?? --- "Chris W. Parker" <[EMAIL PROTECTED]> wrote: > > yeah that makes sense. hmm.. well i'll give you my > ide

RE: [PHP] Unique ID system - need help/ideas

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, AL0

Re: [PHP] Unique ID - again

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 r

Re: [PHP] unique id

*WHY* not use auto_increment? Would the builtin http://php.net/uniqid function not work better? *NEVER* seed the random number generator more than once per script. Call srand() once, and only once. The return() statement will return the MySQL resource ID, which is probably not useful, but all
