Why was my comment deleted? I posted a MB-String version of
wordwrap,
that so far has not been posted by anyone else..
I just looked at php.net/wordwrap and my comment seems to
have been
replaced by golanzakaiATpatternDOTcoDOTil who I'm guessing
is a
PHP.net editor since my comment was rejected at the same
time as this
email was sent.
However, the function that he posted, is not a perfect
replacement of
wordwrap() as it lacks the last parameter "$cut".
That parameter is an
important part of the function. Replacing the code that I
posted with
inferior code does a disservice to the community, even if
the editors
of php think they write cleaner or faster code..
