title: Performance of Singleton Class Instance Method vs. Static Class Method in PHP?
body: <p>I'm interested in objective analysis of which is more performant; calling instance methods of a singleton class or methods of a static class. I've already seen <a href="https://stackoverflow.com/questions/2840912/php-static-db-class-vs-db-singleton-object/2840967#2840967">this</a> so I'm not looking for a discussion about the difference between the two or a discussion of which is "better." I'm only interested in relative performance between the two.  Thanks in advance.</p>
