Removing a dash from the end of $title

[jeffkas]

I'm trying to remove a dash at the end of a title, for the times when a dash appears there (which isn't always).

 

Since my titles are always different lengths, I don't think substr will work.  How can I code the following... 

 

If $title ends with '-', replace with ''

 

Thanks!

rtrim()

<?PHP
  $string = 'sdfsdfsfsdfdfjkdb adfk ahif-fff-';
  $string = $string[strlen($string)-1] == '-' ? substr($string,0,-1) : $string;

  echo $string;
?>

 

Try the above out, works for me

$string = rtrim($string, '-');
