Using variables before you include the file the variable is in

Ian_Moody

Is this possible at all?
I'd like to adjust the <title> and other things according to variables contained in the called file but I obviously have to have those before I call the file. Is there anyway to do this?

No. The scope of PHP says that the only variables you can use are those that are within the $GLOBAL scope (like $POST, $GET, $SESSION, $COOKIE) and which you define within the script.

If you want to include those variables & their values, just include the file; however, you could store them in a session. But it would just be easier to include the file.

Why would you want to use variables before they are defined? It's like driving on a bridge before it's completed.... well not really...crap.... another failed metaphor....

I basically want to do this

<h2>$title</h2>
include("filewith$titlein.php");

so that the title changes depending on what file I'm including

reverse the lines, works perfectly!!

include("filewith$titlein.php");
echo '<h2>'.$title.'</h2>';

But then I end up with the header below the content, when I really need it above. And I still won't be able to use $title in <title></title>

You need to rethink where you declare the variables then.
