Answer 1

You can use this one

'/\[URL[^]]+\](?P<name>[^\[]+)\[\/URL\]/'

But you should probably learn Why.. Here is a good tester that shows that regx at work

Traditionally this is called BBcode ( builtin board code )

https://en.wikipedia.org/wiki/BBCode

There are full PHP implementations of this sort of thing you can use besides regx

If you want both ( optionally the url ) you can use this one

'/\[URL(?:\=\"(?P<url>[^"]+)\")?\](?P<name>[^\[]+)\[\/URL\]/'

And here is that one at work

That last one does require the " around URL, I have seen them done with ' or no quotes at all.
