Re: Question on functions

[elixon <elixon@xxxxxxxxxxxxxxxxxxxxx>]

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 ;-)
