Checking a few strings.

[takn25]

Hi, I want to check two things if some one could help thanks. I am not an expert at REGEX just learning.

 

Firstly I want to check if a string has a - at the end for example.

 

$string= "Lion"; There is no - at the end  I would like to add a  ( - )  . So $string becomes LION-

 

Second thing I want to check for example if the user has inputted some excessive use of BLANK SPACE and turn it  in to just single space for example.

 

I                      ROCK                  THIS          becomes  I ROCK THIS.  Thanks help is much appreciated.

$string .= (substr($string,-1) == '-') ? '' : '-'; 
$string = preg_replace('~\s+~',' ',$string);
