I have an odd thing happening. Can you reference variable that are set
above a function? The below code is not working for me:


<?
$sql ="some sql query";
$result = mysql_query($sql);
$row = mysql_fetch_array($result);
$msg = nl2br($row['message']);

function mycontent(){
?>

Some html code............
<?
echo $msg;
?>
Some more html code.......

<?
}
?>


However this does work:

function mycontent(){
?>

Some html code............
<?
$sql ="some sql query";
$result = mysql_query($sql);
$row = mysql_fetch_array($result);
$msg = nl2br($row['message']);
echo $msg;
?>
Some more html code.......

<?
}
?>

Any reason why it works when the variables are inside the function as
opposed to being outside of it? Thanks!
