Question

I have a textarea where users can submit a post in PHP. I want to check the number of line breaks in a row and reduce it if necessary, for example.

ORIGINAL:

Hello\n
\n\n\n\n\n\n\n\n\n\n\n\n\n
Goodbye

WHAT I WANT IN THE END:

Hello\n
\n
Goodbye

So basically I want a maximum of 2 line breaks in a row.
How can I achieve this in PHP?

Thanks for any help.
