[Phpwebsite-developers] Using the predefined variables

[Adam M. <ad...@tu...>]

I have found that the easiest way to write code using the predefined
arrays provided by PHP is like this:

$GLOBALS["core"]->function($var);

$GLOBALS["CNT_module"] .= $string;

$_SESSION["OBJ_user"]->user_id;

That's just a few examples but it should give you the idea.  If you place
an extract($GLOBALS) at the beginning of your function you run the risk of
having duplicate variable names in your function and clobbering their
appropriate values or getting some data back that you did not intend in
the current function or later in the script.

I hope that makes sense...
