You don't need the last trim()

   $string = substr($string,0,strrpos($string," "));


Actually, it's needed :)
Suppose $string = "aaa bbb ccc" and $length = 9, then:
first substr leaves "aaa bbb "
if we don't have the second trim, strrpos returns 8 and second substr returns "aaa bbb " so, "aaa bbb ..." will be returned instead of "aaa bbb..." :)
