How can I count only the real visitors (i.e. not crawlers, bots, etc.) of a specific page on my website using PHP?
I want to do it as accurate as possible, e.g. the way Stackoverflow counts the the visitors of a specific question.
I currently increment the page counter field in the database for each visit, but that gives unrealistically large numbers of visitors for each page after just a few days. I guess it counts crawlers, bots etc,. and even some browsers hit a page multiple times.
