It should be noted that the behavior of the $break parameter is poorly explained.
If you specify the $break parameter, then *that string defines what the function considers a "newline"*.
Consider the following string:
$str = "Rumplestiltskin Schwartzmenikoff
1534 Gingerbread Lane
Black Forest, Germany";
You are trying to fit this address into a space that only allows for 22 characters, but you want it clear that you're continuing a previous line, so you want a space added. You might try this:
$str = wordwrap($str, 22, "\n>");
If you did that, you would end up with the following output:
"Rumplestiltskin
>Schwartzmenikoff
1534
>Gingerbread Lane
Black
>Forest, Germany"
This is because when you pass it a third parameter of "\n>", it assumes that entire string is a newline character. It's no longer using "\n". In your output, of course, \n is still a newline, so it appears to have extra lines.
If you're looking to wordwrap a multi-line string with something besides a newline character, make sure all existing linebreaks are already delineated with the string you pass to wordwrap().
