PHP beginner here. I have the following in index.php (the two files live in the same directory)... <?php require_once( dirname( __FILE__ ) . '/functions.php' ); ?> <!DOCTYPE html> <html lang="en"> <head> <title><?php echo $nds; ?></title> </head> <body> </body> </html> ...and here is the required PHP file (functions.php)... <? php // test variable $nds = 'Test title.'; ?> This gives me an "undefined variable" error when tested in a browser. Is this an issue of scope?
