What made the $categories variable global ? (Technics)
Hello guys,
I know this question may make me sound very amateurish, but being amateurish I'm so eager to have someone's help hands during my tedious study
I know the the $categories variable got asigned with value at the first place with below statements in main.inc.php:
==============
$categories = get_categories();
==============
Now my question is:- What made the variable Global? Why can we re-use the $categories variable directly in posting.inc.php without haveing to assign value to it again ?
What kinds of technologies and which files did the trick ?
Any detailed explanation would be highly appreciated.
