title: Which is faster? Constants, Variables or Variable Arrays
body: <p>My current web application uses about 30 or so Contants (DEFINE()). I am reading things that variables are quicker. Provided that there is a naming convention to avoid variable overwrites, the only other draw back I see is that these variables would have to be defined as global variables some how in every function.</p>
  
  <p>Which is faster? I use these constants a whole lot throughout my application and will probably be forever adding more to the list and they are used in and out of functions and classes.</p>
