 * So how do you use WordPress’s variable get_option() function to set a variable?
 * I tried:
 * $variable=get_option(‘option’);
 * But I had no luck. Got an error message as “Call to undefined function.”
 * I tried including /wp-includes/functions.php but it made no difference.
 * Anyone got any idea? Thanks!

 * I figured it out. I wasn’t including /wp-includes/functions.php in the file where
   the function was located.
 * When I figured that out, I got another error: Fatal error: Call to a member function
   main() on a non-object
 * It took me 2 hours to figure that one out. The problem was something like this:
 * I was including functions.php in example.php and then including example.php in
   options_menu.php. So in options_menu.php, the include statement was in the body
   section of the page which cause the error.
 * Long story short, include the functions file **within the necessary function**
   rather than at the file level!

 * Usually (for theme development) your functions are put _in_ functions.php – that
   is what it is there for.
