Get character from ASCII code in PHP, Java and JavaScript

The lower case letter „a“ has ASCII code „97“ and can be generated in PHP like this:

  $a = chr(97);
  echo $a;

In JavaScript, the same can be accomplished by:

<script type="text/javascript">
  var a = String.fromCharCode(97);

And this is how it works in Java:

public static void main(String[] args){
  String a = new Character((char) 97).toString();
