PHP removing a character in a string

Question

My php is weak and I\'m trying to change this string:

http://www.example.com/backend.php?/c=crud&m=index&t=care
                                   ^
         


        

Answer 1

$str = preg_replace('/\?\//', '?', $str);

Edit: See CMS' answer. It's late, I should know better.
