docstring: Sanitizes a string to help avoid XSS vulnerabilities.
  
  This function is automatically called when {@link getRequestVar()} is called,
  so you should not normally have to use it.
  
  This function should be used when outputting data that isn't escaped and was
  obtained from the user (for example when using the `|raw` twig filter on goal names).
  
  _NOTE: Sanitized input should not be used directly in an SQL query; SQL placeholders
  should still be used._
  
  **Implementation Details**
  
  - [htmlspecialchars](http://php.net/manual/en/function.htmlspecialchars.php) is used to escape text.
  - Single quotes are not escaped so **Piwik's amazing community** will still be
  **Piwik's amazing community**.
  - Use of the `magic_quotes` setting will not break this method.
  - Boolean, numeric and null values are not modified.
  
  @param mixed $value The variable to be sanitized. If an array is supplied, the contents
  of the array will be sanitized recursively. The keys of the array
  will also be sanitized.
  @param bool $alreadyStripslashed Implementation detail, ignore.
  @throws Exception If `$value` is of an incorrect type.
  @return mixed  The sanitized value.
