Manipulating a string help.

On my site, I am adding hunger so you that your "character" has to eat or else the posts on my forum that I made will show up with a '...' after each word. I am currently going:

$message = $post_from_database;

$message = str_replace(" ", " ...", $message);

Now this works fine. However if the user adds a bunch of extra spaces with no words on them, posts will have random '...' in many places. How can I get this to work so that it only adds '...'
after all the words.

Well, I'm sure a regular expression woudl solve your problem, I'm just having a hard time determining exactly what you want from your post. Are you saying you want to add elipses after each word???

Yes that is it, it should add, '... ' at the end of the word.

You can use explode() to divide you string by space, remove empty elements from a resulting array and then join the array with "... " to a string. Something like this:

$ar=explode(" ",$your_string);
foreach($ar as $key=>$value)
{
   if ($value=="") unset($ar[$key]);
}
$your_string = join("... ", $ar);

I'm not sure about that part with deleting empty elements. You can use (trim($value)=="") condition if the first one wouldn't act as desired.
