I wish to improve upon my regular expression skills. I am creating a journal
object that allows me to post my journals online, while at the same time
maintaining nine different levels of privacy. For example, if I give a user
Level 3 access, then they would be able to see all parts of my entries marked
as Level 3 or below, but nothing above that.
Below is an example entry. I'm not sure how to go about doing this. My
experience with regular expressions is somewhat limited. I could use a
statement like this:
ereg("[LEVEL1].*[/LEVEL1]", $Contents, $Match);
But if you look at the contents below, you'll see that there are two places
where [/LEVEL1] is at, so that statement will mark the entire page as Level
1, rather than just the first sentence, and the last sentence.
Plus, that statement won't really work. I need a way to say: Replace
[LEVEL1].*[/LEVEL1] with ###LEVEL1### and return the contents into an array
for me. That way, in the second phase of parsing, I can either put the
string back into the page at exactly the same point, or I can put "Level 1
Access Required - Log In" instead.
Any help would be greatly appreciated. Thank you in advance.
