automatic line-break of textarea inside a form possible with PHP?

Question

I know about the nl2br function... But is there a way to set a maximum length of a line? Im using php to get results from a form, which contains a textarea. I dont want words to get broken to newlines, like the word 'example' to become 'exa
mple'

Thanks

You can use wordwrap to force a line break:

wordwrap($str, 123, "<br>\n", true)
