Should empty values be allowed in the encoded data? Specify any of the following:

  • false (bool): to exclude all empty values (this is the default if not specified).
  • true (bool): to allow all empty values to be retained (thus no point in calling this function).
  • Specify array of keys (from data) that should be retained if you want some retained and not others.
  • Specify array of literal empty value types to retain, i.e. [ 0, '0', array(), false, null ]
  • Specify the digit 0 to retain values that are 0, but not other types of empty values.

Perform type conversions where appropriate? i.e. convert digit-only string to integer (default=false).
