Re: [PHP] Question on functions

Or you can use superglobal variable $GLOBALS that is array containing 
all GLOBAL variables. This variable is superglobal thus does not need to 
be declared global using 'global $GLOBALS;' statement. Works anywhere.

function database() {
        ... $GLOBALS['array'][0], $GLOBALS['array'][1] ...
}

Tip: I recommend to not use GLOBALS for this type of data. Better use 
function parameters -> function database($host, $user, $pwd, $db) {...} 
It will save you time when your application grows and starts clashing 
with other global variables or third party pieces of code ;-)

My question is in regard to passing global variables to a function. 
Here is my code, any idea why it is not working?  I suppose my 
understanding of a global variable being able to be used within a 
function is off?

global $array = array( "0" => "hostname", "1" => "username", "2" => 
"password" );

function database()
{

You need to declare it global within the function...
function database()
{
  global $array;
  ...
thanks, it figures it is something easy like that... =)
