Trying to create a site-template system.. and..

First.. here's the synopsis of what I'm trying to do: I'm working on a site where everything is based off a really simple template system I'm using, see the chunk of my index page that deals with the plates for example: --------------------------------------------- $tmpl_file = fopen ("./template.htm", "r"); $tmpl = fread($tmpl_file,16000); $tmpl = str_replace("{title}", "$title", $tmpl); $tmpl = str_replace("{header}", "$header", $tmpl); $tmpl = str_replace("{header_url}", "$header_url", $tmpl); $tmpl = str_replace("{header_home}", "$header_home", $tmpl); $tmpl = str_replace("{header_cat}", "$header_cat", $tmpl); $tmpl = str_replace("{header_caturl}", "$header_caturl", $tmpl); $tmpl = str_replace("{header_title}", "$header_title", $tmpl); $tmpl = str_replace("{pretext}", "$pretext", $tmpl); $tmpl = str_replace("{content}", "$content", $tmpl); $tmpl = str_replace("{content_source}", $page_source, $tmpl); eval("echo \$tmpl;"); --------------------------------------------- The template file looks like "blah.. blah.. {title}.." the code above then takes the {blah} tags, and turns them into variables, which are defined in the actual content pages (which are included (via an include(); function..) The content files appear as: --------------------------------------------- $title = "testing"; $content = "etc"; --------------------------------------------- And so on.. My problem is.. that when I do something like --------------------------------------------- $content = show_source("/path/to/file"); // or $content = "Blah.. blah.. ".include("/some/file").".. some more blah.."; --------------------------------------------- It includes the files (or executes the code that is assigned to the variable), however it all appears OUTSIDE the template. To see what I'm saying, see http://olypen.com/ryan/go/main/news or http://olypen.com/ryan/go/source/source_index .. that will give you a better idea as to what I'm saying. Anyone have any thoughts/explanations as to why this is happening? I can provide more source.. or info if needed. Thanks in advance! -Ryan
