I took a look at the /array article today, don't know why but I did.

there are some nice examples.
but no output.

Newbies won't be able to see whats in an array, when they don't know what the output will be.

I suggest you to put a print_r(); output for the arrays..

the php function you posted today (limit words)
has the same problem.

you put an 'how to use' in there, but no output.

I had to lookup the preg_split function since i've never used it before.
then I knew what the function does.
(btw, you are looking for a space, wont split(" ", $str); work?)

I see your point about outputting the array. I will review these articles over the weekend.

re: wont split(" ", $str); work?

I had thought of that and also str_word_count() before. Think about this string:

"the goat.\r\n\r\nWell, whatever"

'goat.\r\n\r\nWell,' would be one word if the function just looks for ' '.
