A simple template class - compiled (after the simplet class is enhanced)_PHP tutorial

After the simplet class released last time (http://bbs.phpchina.com/thread-85257-1-1.html), it was found that there are many defects, such as not supporting multi-dimensional arrays, comments and no Caching function, this time I added all these functions! ! !
If you are interested, I will make a tutorial next time to talk about some of my ideas and methods of writing this class! ! ! If you support, you can follow me and support me!
PHP代码:
simplet.class.php
class SimpleT {
    private $t_vars;

        $this->cache = 0;
        $this->cache_dir = ./cache/;
    }
    public function setDir($dir, $type = template) {
        if(is_dir($dir)) {
            if($type == template)
                $this->templates_dir = rtrim($dir, /)./;
            elseif($type == template_c)
                $this->templates_c_dir = rtrim($dir, /)./;

            }
            $content = preg_replace("/<%{([^(}%>)]{1,})}%>/", "templates_c_dir}simplet_comp_$1.php; ?>", $content);
