note 4243 modified in ref.strings by sander

I had the problem that in some of the guestbooks I programmed, people entererd trash like 400 characters without spaces and such. Without any spaces there was no way to break the lines and the whole guestbooked looked screwed. I wrote this little function that makes sure no words are more than a specified number of characters long. If a word is too long, spaces are inserted to get the word to the maximum length allowed. Maybe it's useful to some of you: function strmaxwordlen($input,$len) { $l = 0; $output = ""; for ($i = 0; $i < strlen($input); $i++) { $char = substr($input,$i,1); if ($char != " ") { $l++; } else { $l = 0; } if ($l == $len) { $l = 0; $output .= " "; } $output .= $char; } return($output); } --was-- I had the problem that in some of the guestbooks I programmed, people entererd trash like 400 characters without spaces and such.
