PHPcamp aims to provide a platform where everyone can bring interesting links, news and share their knowledge that are helpful to other web developers. It provides publishers with a chance to easily show their articles to others and gain some readers; most importantly it provides readers an easy way to keep an eye on latest things in PHP world, at the same time, giving them a chance to learn new things every day.
The site takes in user-submitted articles/blog posts/etc and they're dropped into the "freshly arrived" list for public consumption. If a link gets enough attention, its listed under the "getting hotter" and "boiling" sections progressively. Check out their blog for more information.
