title: Substring function that is like the PHP function?
body: <p>is there a function like PHPs substring? I saw Left and Mid but those all make me specify the length of what I want the string to be.</p>
  
  <p>Here is PHP's function example:
  $rest = substr("abcdef", 1);    // returns "b"</p>
  
  <p>I just want to be able to take a string and start it at a certain point, not end it as well.</p>
