Implement loop into template parser

I am building a very lightweight framework and would like a custom template parser. I of course know about other solutions such as Smarty, however that is much overkill for what I need.

I've built simple template parsers before but never figured out how to use loops. I am thinking something on the idea of Smarty's foreach loops, or maybe phpBB's loop blocks. Unfortunately I don't really have time right now to paw through those applicati开发者_运维技巧ons, so what is the simplest way to implement loops into a template parser?

It must be able to handle multi-dimensional arrays as well.

Here's the general idea of how to do it...

You need to set up your loop start and ending parameters. So something like:

{LOOP_START:users}
    <p>{name}</p>
{LOOP_END:users}

Then in your template code, you want to grab the loop placeholder from {LOOP_START:users} to {LOOP_END:users}. You also want to grab a snippet of everything between those tags. Loop through your array and replace the vars in the snippet, then replace the whole placeholder with your new output. Here's the basic idea:

$output = your_method_to_get_the_full_template_contents();
$loop_with_tags = your_method_to_find_the_loop_tags_and_content($output, 'users');
$loop_inside_tags = your_method_to_get_the_loop_contents($loop_with_tags);

$loop_output = '';
foreach($users as $user) {
    $loop_output .= str_replace(array_keys($user), array_values($user), $loop_inside_tags);
}

$output = str_replace($loop_with_tags, $loop_output, $output);
