A few tips for starting out with regex:
1) use PCRE, they are faster and ultimately more useful than the POSIX variety
2) Build up your regex step-by-step and test it at each step to see what is
being matched and what isn't (and why it isn't)
3) Use parentheses () to enclose the bits you want to 'capture' (extract).
4) Practice
5) More practice
So for your first example, as a first draft you can just capture everything
between the begin marker and the end marker:
$doo = '{!STATISTICS:starbucks!}';
preg_match('/\{!(.*)!\}/', $doo, $match)
$match[1] now contains: STATISTICS:starbucks
You can explode() it to get the constituent parts.
Or you can refine your regex:
preg_match('/\{!(.*):(.*)!\}/', $doo, $match)
So basically your first draft would match a large chunk of stuff, your
successive drafts would fine-tune it until eventually you're matching exactly
what you need.
