在<div>之后阻止<br>

Question

I'm wondering how to remove all <br/> existing right after a div tag. Is this possible? As soon as some regular text has been printed after the <div> tag, <br/> should be allowed again.

The <br/> is added because of nl2br.

I don't want the users to be able to break the formatting of my pages by hitting enter a lot. This would be great to be able to fix.

Thank you.

$string = preg_replace('/<div>(<br[^>]*>\s*)+/', '<div>', '$string');
