[PHP] Does anyone know how to set the max newlines in a row?


Question

Fellow Neowiners,

I am looking to control some input on a textarea field. I want to be able to let users hit return twice, to start a new paragraph or line with a whitespace between it, but no more than that. I have seen some regex that can removes multiple new lines (2 or more) but like I said I want users to be able to space their text of if they want.

Is anyone familiar with some code that can remove new lines when there are 3 or more in a row, but leave 1 and 2 alone?

Cheers.
