替换.tpl文件中的变量

Question

Situation at this moment

I'm using this function:

public function fetch($file){        
    $file = $this->options['template_dir'].(string)$file;

    if(file_exists($file)){
        ob_start();
        if($this->options['extract']){
            extract($this->vars);
        }
        include $file;
        return ob_get_clean();
    }else{
        throw new Exception('De ('.$file.') template bestaat niet.');
    }        
}

Basically it just replaces <?php echo $name; ?> from the tpl with the data of $tpl->name.

The question

I would like to start using {$name} instead of using <?php echo $name; ?> in my TPL files. Can anyone point me in the right direction for replacing this with the data of $tpl->name?

What I've tried

I tried to do it with a regex, trying to find the { and } and then replace it, but it will only output $name as text.

I would probably go with a regex, but here is an alternate. You could also foreach through $this->vars keys:

$template = file_get_contents($file);
$vars     = explode(',', '{$'.implode('},{$', array_keys($this->vars)).'}');
$output   = str_replace($vars, $this->vars, $template);
