Split up string into chunks of words by char length

[ejaboneta]

I'm trying to split up long text by words up to 1000 characters. What I mean is that I can't have a string be longer than 1000 characters. I know how to split up by 1000 characters, but then words get cut off at the end. So I figured I could preg_split it using something like this:

$array = preg_split("/.{950,1000} /",$content);

 

But that doesn't seem to work...
