Can anyone tell me what this boolean is for?

Hi there.

I have this line on my php script:

$nameBroken = wordwrap($row['Name'], 50, "<br/>", true);

I just copied this from other script, and now am trying to understand what this "true" represents so that I can confidently use this wordwrap function on other work.

So can anyone please tell me what this boolean value of "true" represents??

Thanks

google "php wordwrap"
