One by one according to the following:<br />"; echo "<br />".$rightt = strlen(ltrim($string)) - strlen(trim($string))." empty position(s) from right."; echo "<br />".$leftt = strlen(rtrim($string)) - strlen(trim($string))." empty position(s) from left.<br />"; $length = strlen($string); for($x = 0; $x < $length; $x++){ $letter = substr($string, $x, 1); if($letter <> " ") echo "<br />Position&nbsp;&nbsp; $x ===> &nbsp;&nbsp;".substr($string, $x, 1); else echo "<br />Position&nbsp;&nbsp; $x ===> &nbsp;&nbsp; Empty"; } ?> the output is: Hello World!
