Hi Chris,

Thanks.  Oops, I figured it out as I was writing this.

Essentially, my web page call a template.php file.  The body text is already
inside a function called render_body() that's why variable that should be
global is not global (because it is in local scope of a function).  Well, in
this case, I can still force local variable into global scope by doing
something like this:

function render_body() {
	$var1 = "this is a locally defined variable";
	$_GET['var1'] = $var1;  // $var1 is local variable defined in
render_body() function
}

Then in another function call, the variable like this

function someOtherFunction() {
	$var1 = $_GET['var1']; // because using global $var1 will not work
	echo $var1;
}

Is this okay?

Thank you,
Pinyo

That doesn't seem entirely right-- global $var1, $var2; should still 
work just fine. What's been turned off is probably "register_globals" 
which only applies to server environment and CGI request variables, not 
variables that you declare at runtime.

If either $var1 or $var2 are really $_GET['var1'] or $_GET['var2], then 
you'll need to explicitly assign them in global scope like so:

<?php

function foo() {
    global $var1, $var2;
    return $var2.$var1;
    }

$var1= $_GET['var1'];
$var2= $_SERVER['DOCUMENT_ROOT'];

?>

Should work...
