How about this:

function fullTrim($str)
{
    return trim(preg_replace('/\s+/', ' ', $str));
}

Is preg_replace also perform ltrim n right trim what should i do in order to perform both operation in one go. – Rahul Singh Nov 03 '11 at 04:16
I would use preg_replace twice, one to do the right and left trim and the other two remove the excessive whitespaces, do you understand how to do the first operation? – lc2817 Nov 03 '11 at 04:18

function customTrim($str)
{
   while(strpos($str,"  "))
   {
     $str = str_replace("  ", " ", $str);
   }
   return $str;
}

easy and understandable for beginners.
