Question

I’m in need of a regular expression that can remove unnecessary/extra parenthesis in a string if found.

Example:

Bob Barker LIVE! (((Don't Miss out!)))

Wanted Result:

Bob Barker LIVE! (Don't Miss out!)

I don’t care if users you them, as long as they don’t over use them, and make sure to close them.

Thanks for any feedback.

Answer 1

That’s easy enough.

preg_replace('~[\(\)]+~', '', $string);

Edit: I didn’t read your whole question. You still want parenthesis, just not duplicates.

preg_replace(array('~\(+~', '~\)+~'), array('(', ')'), $string);
