HTML5 best practices issue

So, I've read recently some posts about HTML5 best practices and all of them have the following practice:

"Use id attribute instead of name attribute"

Is that right? I mean, how am I going to handle forms in PHP, for example, if not by inputs' name attribute?

Look here for reference:

Long story short, ID is not meant for naming form elements.
