It's a good function but PHP already had a core function that can do the same, and better. Take a look at the wordwrap function docs.

No no no no no... you didn't get it.
the "wordwrap" function does the "wordwrap" of the win32 controls, returning a paragraph...
THIS CLASS returns a new string limited to certain length, but just until the last "complete" sub-string, avoiding annoying incomplete words at the end of the string. It is useful in forums or mails where you have limited length of text (for some reason)...
Maybe there is a core funtion to do this, but it is NOT wordwrap hehe...
cheers.

Paulo, the only difference is that this class returns only the first line that would be returned by the wordwrap function.

You can simplify it by doing this:

echo strstr(wordwrap(preg_replace('/\s+/', ' ', trim($textstring)), 55, '<*>'), '<*>', true);

wordwrap function looks like a mess if you use it directly, so the idea of this friend was doing it as simple as this:

echo $delimiter->limit(55,$textstring);

versus:

echo strstr(wordwrap(preg_replace('/\s+/', ' ', trim($textstring)), 55, '<*>'), '<*>', true);

Anyways i agree with you that the class code can be "simplified" using the wordwrap function, i think this class has too much code... but the idea is good.
