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" :)
