I wanted to attach a unique ID to a link click. At this time it's about 10-35k daily depending on a day. I figured that if I use a date stamp plus an increment of +1, I'll get a unique ID for every click.
How do I setup PHP in the simplest way to do an increment of +1 starting from either 0 or 1 every new day?
This is for a redirect, so all my tracking code is in a PHP script which directs visitors to an ending URL. It's used for affiliate tracking, direct linking from Google, Bing, Yahoo, etc.
