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" :)
