When assigning a vaule to a variable, it pass by value nomally. What does it mean? See the snippet code below. (more…)

I have recently come across some differences in the way that people instantiate classes in PHP. I was thinking which is the best to use, both work so it is more of a coding standards decision.

or 

$var = new classname();
