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..." :)

Think again. 

strrpos returns 7

;-)


Actually:

$str = "aaa bbb  ccc";
$str = substr($str,0,9);
echo strrpos($str," ");


Outputs 8 :) There is a mistake, though:

instead of
  $str = substr($str,0,strrpos(trim($str)," "));
it should be
  $str1 = trim(substr($str,0,strrpos($str," ")));

Otherwise if it's trimmed first, it'll become "aaa bbb" and strrpos will return 3, resulting in "aaa" :)
