KD2FW (KD2 is not FrameWork) is a collection of tools and libraries developed for the KD2.org projects over the years.

<h2>Features:</h2>
## Features:

  *  Lightweight
  *  Small
  *  Fast
  *  Code is simple and straightforward to read
  *  Simple API
  *  Easy to extend and adapt to own needs
  *  No extra dependency, you don't have to install any other library to use it
  *  Each component can be used outside the framework, there is no internal dependency
  *  PHP 5.4+ object code
  *  PHP 5.6+ object
  *  Components comes with full documentation, examples and tests

This framework is used for a couple of websites serving millions of web pages each day.
This framework is used for some websites serving millions of web pages each day.

WARNING: there is currently no release cycle of kd2fw, all components are considered stable, and no backward-incompatible changes should be made.

See the [Roadmap] for planned features.

<h2>PHP Components (version 1.0)</h2>
## PHP Components (legacy 5.6 branch)

  *  [BubbleBabble]: encodes and decodes using the [http://bohwaz.net/archives/web/Bubble_Babble.html|Bubble Babble] binary data encoding. Much like base64 but makes actually pronounceable pseudo-words.
  *  [CacheCookie]: stores session data in a cookie (using MsgPack if available or JSON as a fallback), without using session files. For MsgPack you can use [https://github.com/onlinecity/msgpack-php|this pure PHP implementation] but the PECL module "msgpack" is much faster.
  *  [DB]: abstraction layer to PDO with useful helper methods
  *  [DB_SQLite3]: abstraction layer to SQLite3, same API as [DB]
  *  [Delta]: to compute and apply deltas between two revisions of the same file (PHP port of Fossil delta algorithm). Allows to store only differences between two edits of a text, may be useful for example in CVS or a Wiki.
  *  [ErrorManager]: error and exception handler with dev/prod mode, email reporting and more, like a lightweight version of [https://github.com/nette/tracy|Nette Tracy]
  *  [FeedParser]: parses RSS and ATOM feeds, any version, even if they are invalid XML
  *  [Form]: to validate and filter form fields, including CSRF protection
  *  [HTMLDocument]: DOMDocument/DOMNode wrapper that adds support for querySelector/querySelectorAll methods (easy to use CSS selectors, internally transformed to XPath queries, so it is quite fast)
  *  [Image]: a simple and fast image library providing resize, image informations and image thumbnail through EPEG (JPEG only), ExactImage, GD, ImageMagick or ImLib (will use the fastest available option).
  *  [Image_Blob]: to get image size (supports PNG, JPEG and GIF) and EXIF orientation from image blobs, doesn't require any library
  *  [Image_EXIF]: deals with EXIF data from JPEG files
  *  [Karto]: mapping/GPS tools
  *  [Mail_Message]: parser/writer of email MIME messages (with support for MIME encoded messages and attachments)
  *  [MemCache]: memory cache wrapper (APCu, XCache, Opcache, etc.)
  *  [BubbleBabble](wiki:BubbleBabble): encodes and decodes using the [http://bohwaz.net/archives/web/Bubble_Babble.html|Bubble Babble] binary data encoding. Much like base64 but makes actually pronounceable pseudo-words.

  *  MikroMarkupBBCode: fast and lightweight BBcode parser/renderer for HTML
  *  [MiniSkel]: template-based programming language compatible with the SPIP CMS
  *  [Mustachier]: lightweight template engine based on Mustache
  *  [QRCode]: generates QR codes
  *  [Security]: common security functions, including anti CSRF tokens
  *  [Security_OTP]: secure one time password generator/verifier, compatible with TOTP/HOTP and Google Authenticator
