(JavaScript) Generate unique ID - jatkins

Not necessarily perfectly unique, but the chances of two identical IDs being generated are insanely remote (so not really a GUID generator, but looks like it). You'll need to clear it up -- I pulled it out of an object containing miscellaneous functions.

(PHP) Unique Code Generator - fmdfrank

For a project I needed to generate a unique code for each user the client would input manually. Each user would have four fields (first name, last name, email, zipcode). Omitting the email addresses ensures unique output because we reduce the chances of characters like; '@', '.', and strings like 'com' being reused everytime. It's simple, it's efficient and it's not overcomplicated.

Some times you need to generate a code for a field in a db and that code can't be repeated either... Yes, I know that if two people submit their data at almost the exact same time that it could be possible that they have the same code. OMG OMG OMG! I'll take the 0.0000000001% chance that it will happen. You could get around this by generating a separate table of pre-made codes and each time you use one you take it and mark it as used.

(JavaScript) array_unique - jatkins

Released into the public domain. `array_to_modify` is required; `remove_empty_items` is an optional boolean argument. [find_index](http://snipplr.com/view/37102/) is required because some versions of IE don't feature `Array.indexOf`.

If you have large integers and you want to shrink them down in size for whatever reason, you can use this code. Should be easy enough to extend if you want even higher bases (just add a few more chars and increase the base).
