Topic: [Trim/Truncate] Only first word?

I'm using this code to limit the subject to 5 letters (don't ask why wink )

.$subject_truncated = pun_htmlspecialchars(trim(substr($cur_post['subject'], 0, ($max_subject_length=5)))).

But now I want it to display only the first word of the subject-line. Can you help?

.$subject_truncated = pun_htmlspecialchars(trim(substr($cur_post['subject'], 0, strpos($cur_post['subject'], ' ')))).

I *think* that should do it, although I'm not sure about the order of the arguments in strpos()

Edit: I corrected the order of arguments -Smartys
Edit2: Mmm, an underscore somehow got added -Smartys

It doesn't work...

I don't think strpos() is the correct way to get what I want.

I want this:
Original Subject: "News: blabla blaah blaah?"
to
Trimmed Subject: "News"
So only the first word, which I can then use to define a class of a div.

I switched the arguments of strpos(). Change them and it should be fine.

But I edited your post to correct the order tongue
And now it should work, the code had an extra underscore hmm

Even with the correct order, it doesn't output anything.

Are you sure there isn't another method? I'm not convinced that strpos() is the correct way to do this.

Why? It makes sense
substr takes from 0 to the return value of strpos. strpos is supposed to return the position of the first occurance of the given string (here, a space).

I mean, you could do something like explode the string using spaces as the delimeter and use the 0th value of the new array, but substr/strpos seems to make more sense

I replaced the space with an ":", and now it works!
(Oh, and when I try " " it doesn't work, maybe a sort of character problem?)

Eureka.
