I'm creating a very simple PHP templating system for a custom CMS/news system. Each article has the intro and the full content (if applicable). I want to have a conditional of the form:

```
{continue}click to continue{/continue}

```

So if it's possible to continue, the text "click to continue" will display, otherwise, don't display this whole string. So far, it works like this: if we can continue, remove the {continue} tags; otherwise, remove the whole thing.

I'm currently using `preg_match_all` to match the string in the second case. What is the best function for removing the matched text? A simple `str_replace`, or something else?

Or is there a better way to implement this overall?
