Then link directly to the original article, and indicate the original author. Feeds provide both of these pieces of information. Right now, ALL articles indicate they are written by Ali El Manini (though I will admit that many include the original author in the title, the author listed is Ali, in both the articles and the feed). NONE of them link back to the original — which is alone enough reason for people to ask that you stop republishing. Add on to this that many are clearly the truncated versions aggregated by Planet PHP (which PROPERLY attributes the original author and links back to the original article), there’s even less indication of how to find the original in order to get the full version.
At the very least, this site adds confusion to the google results for given topics. It definitely violates copyright by republishing without permission. (Planet PHP only publishes if you have explicitly given them permission.)
