I have this already at my site.

A) the header.php file prints out a header and sets up a table, the
lefthand cell of which is my menu, the right hand cell is the requested
page.  the footer closes the table.

B) while generating the header, the first things "printed" are the
standard <HTML><HEAD><TITLE>, after which, I grab the title from the
requested page and print that, then close the </TITLE> and continue
generating the pretty pictures and top level menu.

/*                                                                      */
/**     determine a page title so the user's history will              **/
/**   have something usefull in it                                     **/
/*                                                                      */
    $Page_Title = 'Raytheon Company Intranet';
    $temp = $parse_temp = $description = '';
    if (is_dir("$Current_Directory/RCS") &&
file_exists("$Current_Directory/RCS/$
page,v"))
    {
       $description = exec ("rlog -t $Current_Directory/$page | grep -v
\":\" | g
rep -v \"^=====\" | grep -v \"^\$\"");
    }
    if ($description == '')
    {
       if (file_exists("$Current_Directory/$page") && $handle =
fopen("$Current_D
irectory/$page", 'r'))
       {
          $temp = fread($handle,4096);
          $parse_temp = spliti ('title>', $temp);
          $temp = ltrim($parse_temp[1]);
          $parse_temp = split('<', $temp);
          $description = rtrim($parse_temp[0]);
          if (eregi ('parse_temp', $description))
          {
             $description = '';
          }
       }
    }
    if ($description != '')
    {
       $Page_Title = $description;
    }
    print "   <TITLE>\n   $Page_Title\n   </TITLE>\n\n";
