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_BACKGROUND = "gfx/gradient.gif";

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

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

}
or declare them as constants:

define('HTML_BODY_BACKGROUND','gfx/gradient.gif');

function firstOne {
echo HTML_BODY_BACKGROUND; // 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_BODY_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_BACKGROUND;

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

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

Happy Coding :-)
