[wp-hackers] Organizing my theme's functions.php file

[Brad Parbs]

There's a few things you could do to improve the structure of the 
functions.php file.

One thing quite a few people do is create a folder `inc/` and put 
different files there, like `scripts.php` that contains script 
functionality, `customizer.php` that holds all the theme customizations 
stuff, etc. Then just include those files in your functions.php.

You could also move a lot of your functions to a theme-specific plugin 
or multiple plugins, keeping it pretty organized there.

If you're using prefixed functions `foo_bar_theme_setup(){}`, and that 
prefix is very unique, you don't have to worry about the 
function_exists, unless you plan to override it later. I prefer wrapping 
every function in that, so you can always override them easy later.

Moving all of the hooks into a function is a good way to go, as well.

Good luck!
