README

Parser and serializer for the Structured Field Values for HTTP specification.

Installation

Using composer:

composer require gapple/structured-fields

API

The Parser class provides static methods to convert a header string to structured data.
If the string cannot be parsed, a ParseException is thrown.

Parser::parseItem(string): Item;
Parser::parseList(string): OuterList;
Parser::parseDictionary(string): Dictionary;

The Serializer class provides static methods to convert structured data to a header string.
If the input cannot be serialized, a SerializeException is thrown.

Serializer::serializeItem(mixed, ?object): string;
Serializer::serializeList(iterable): string;
Serializer::serializeDictionary(object): string;

Special Types

Serializer will accept string or any Stringable object as an Item value, but will throw a SerializeException if it contains any characters outside the printable ASCII range.

Special Item types must use a decorating class in order to be serialized correctly:

• Byte Sequences (\gapple\StructuredFields\Bytes)
  A string containing binary data.

  Serializer and Parser handle base64 encoding and decoding the provided string.

• Display Strings (\gapple\StructuredFields\DisplayString)
  A string that includes Unicode characters.

  Serializer and Parser handle percent-encoding and decoding non-ascii characters.

• Tokens (\gapple\StructuredFields\Token)
  A short textual word with a restricted character set.

• Dates (\gapple\StructuredFields\Date)
  An integer timestamp

  Serializer accepts any object that implements \DateTimeInterface.
  Parser will return a \gapple\StructuredFields\Date object.
