variable scope problem?

J
I have a page search.php which uses Top.php and Bottom.php to do most
webpage stuff common to all pages. Top.php includes/requires
KTConstants.php .
Top.php can't see Constants/variables like $favoriateColor ='234566'; defined
in KTConstants.php
I tried include instead of require.
I tried using $GLOBALS['KTPTBlue']; perhaps I didn't do it right.
The global keyword gives me an error...expecte d = or something.
*************** *TOP.PHP
<?
require_once("K TConstants.php" );
require_once("P atientResults.p hp");
require_once("B uildForm.php");
require_once("B ottom.php");

function Top($redorblue)
{
//if ( $redorblue == 'red')
$KTPTTopColor=$ KTPTRed;
else
$KTPTTopColor=$ KTPTBlue;

echo $KTPTBlue; //Doesn't work
echo $KTPTTopColor; //Doesn't work

echo '<html><head><t itle>Search Page</title></head><body>';

echo "<table bgcolor='$KTPTT opColor' width = 800>";
echo '<tr><td>';
echo '<a href=search.php >Find</a>';
echo '<a href=add.php>Ad d</a>';
echo '</td></tr>';

}
?>
*************** KTConstants.php
<?
$KTPTRed = 'FF9999';
$GLOBALS['KTPTBlue'] = '6666FF'; //tried both
$KTPTServer='';
$KTPTDatabase=' ';
$KTPT='';
?>
The problem is that the above
echo bgcolor='$KTPTT opColor'
always comes out blank on view source.

Even when I insert into top.php.
echo $KTPTBlue; nothing happens.
Although it works when I echo it in KTConstants.php .

Thanks in advance,
-JB

See Example 12-2 at
http://www.php.net/manual/en/languag...bles.scope.php. Note where
the "global" keyword is used.

Or use the $GLOBAL["global"] thing in your function rather than the
contants file.
