Before coding PHP I used Roxen and their "RXML" language, which was 
pretyt much just fancy HTML (RXML stood for Roxen Markup Language) and 
they had variable templating in strings. When moving to PHP I missed 
this.

So I have this templet string for headline formatting in blog posts 
(for instance):

    $template = "<h2>#headline#</h2>
     #date#, <span class='subline'>#category#</span>";

And then I have an array with the blog post:

    $article = array(
        "headline" => "Hello world!",
        "date" => "2012-04-23",
        "category" => "Fun stuff"
    );

And I have this function I call "parserxml()" which is "Parse rxml" 
not "parser xml" :)

    function parserxml($string, $var = false) {
        # RXML 1.0
        $string = preg_replace("/#([a-z]+)#/se", "\$var['\\1']", 
$string);
        # RXML 2.0
        if (preg_match_all("/&([a-z_A-Z]+)\./i", $string, $matches)) {
            foreach($matches[1] as $m) {
                global $$m;
            }
            $string = 
preg_replace("/&([a-zA-Z_]+)\.([a-zA-Z_]+);/sei", "\${\\1}['\\2']", 
$string);
        }
        return $string;
    }

Which I use as such:

    print parserxml($template, $article);

You may also note that there is support for "RXML 2.0" in that 
function as well, which used a slightly different syntax that could 
define scope as well:

    $template = "<h2>#headline#</h2>&user.name;"

The second part would globalize $user and replace that with 
$user["name"].
