Accessing variables outside a function... possible?

[Leigh Riley]

Hi,

Can someone tell me if the following is possible?

I have a file containing some STATIC variables, and some functions e.g.
-------------------------------------------------
$ARCHIVE_INPUT_ FILES = false;
$ARCHIVE_OUTPUT _FILES = false;
$ARCHIVE_CONFIG _FILES = false;
$HTML_BODY_BACK GROUND = "gfx/gradient.gif";

function firstOne
{
// Do something e.g.
echo $HTML_BODY_BACK GROUND;
}
-------------------------------------------------

The functions CANNOT see the variables I have declared at the top, so is
there anything I can do make the functions see the variables i.e.
declare them differently?

Thanks!

- Lee

function firstOne {
global $HTML_BODY_BACK GROUND;
echo $HTML_BODY_BACK GROUND;
}


or declare them as constants:

define('HTML_BO DY_BACKGROUND', 'gfx/gradient.gif');

function firstOne {
echo HTML_BODY_BACKG ROUND; // no $ sign == constant
}

declare them as global in the funciton

global $ARCHIVE_INPUT_ FILES;

Well ... if they're STATIC variables make them constants :-)
That way you can see them inside the functions

<?php
define('ARCHIVE _INPUT_FILES', false);
define('ARCHIVE _OUTPUT_FILES', false);
define('ARCHIVE _CONFIG_FILES', false);
define('HTML_BO DY_BACKGROUND', 'gfx/gradient.gif');
?>


Failing that you can declare the variables global in the function:
<?php
function firstOne
{
global $ARCHIVE_INPUT_ FILES, $ARCHIVE_OUTPUT _FILES;
global $ARCHIVE_CONFIG _FILES, $HTML_BODY_BACK GROUND;

// Do something e.g.
echo $HTML_BODY_BACK GROUND;
}
?>

or maybe access the $GLOBAL array inside the function
<?php
function firstOne
{
// Do something e.g.
echo $GLOBALS['HTML_BODY_BACK GROUND'];
}
?>

Happy Coding :-)
