This project provides you a way to easily download a League of Legends replay game which still in process (ingame), like lolking or op.gg feature. Replays are stored in your server and can be watched at any time.
All download files can be decoded to parse them.

• A built-in replay decoder for each files (chunks & keyframes)
• An asynchronous system, allow to download some replays at the same time and save the log into the replay folder, it needs the CLI dependency : https://github.com/EloGank/lol-replay-downloader-cli
• Download previous data if you start the download process after the start of the game
• Can wait for the start of the game if you start the download process too early
• Easily extendable and configurable.

Simply clone this project and run the composer install command. If you don't know what is Composer, read the dedicated documentation.

To configure the library, you have some $options parameters in the classes constructor. Just pass an array to override them, see the getDefaultOptions() method of each class.

See the "download and decode example", which overrides two configurations of the ReplayDownloader class.

Some examples are available in the examples repository folder.

Some regions (not all) are listed in the LoLNexusParser class as constants.

For the game id and the encryption key, it's a few harder. Indeed, the official Riot API doesn't provide yet an API to retrieve this data.
To get it, you have to use an unofficial API, like this : https://github.com/EloGank/lol-php-api, please see the route game.retrieve_in_progress_spectator_game_info. Note that using other route is not allowed, by the new Riot Terms of Use (see "Important notes" below).

For testing purpose, you can simply go to spectating websites like lolnexus, click on "Spectate" button on a game, and you'll have the region, game id & encryption key in the command line to launch the game, see the end of the line :

"C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\releases\0.0.1.xx\deploy\League of Legends.exe" "8394" "LoLLauncher.exe" "" "spectator SERVER_ADDRESS ENCRYPTION_KEY GAME_ID REGION"

Example :

"C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\releases\0.0.1.68\deploy\League of Legends.exe" "8394" "LoLLauncher.exe" "" "spectator 185.40.64.163:80 nwP+BEYqHgk4sElnU2uRogoxGPUw1dzE 1234567890 EUW1"

So, you can extract :

A LoLNexus PHP parser exists here : https://github.com/EloGank/lol-replay-downloader/blob/master/examples/utils/LoLNexusParser.php

Usage is simple : you juste have to select the region by calling LoLNexusParser::parseRandom($regionId) or LoLNexusParser::parsePlayer($regionId, $playerName) methods and it will bring you all parameters for running a command by calling LoLNexusParser::getRegion(), LoLNexusParser::getGameId() or LoLNexusParser::getEncryptionKey() methods.

Example is available here : https://github.com/EloGank/lol-replay-downloader/blob/master/examples/download-replay.php#L32-L48

According to the new Riot Terms of Use (1st October 2014), using data from another source of their official API is not allowed. So using data by parsing decoded files is not allowed. This project provides a way to decode file only for teaching purpose.

You can download a full game only if you start the download process before the ~8th ingame minute. Otherwise, you won't have the start of the game.

A game is still viewable if the game hasn't been updated. If one or more updates has been applied since the replay has been downloaded, there may be has some ingame glitches (movements, monsters, sounds, etc).

Feel free to open an issue, fork this project or suggest an awesome new feature in the issue tracker.
