# tg-file-decoder ![build](https://github.com/danog/tg-file-decoder/workflows/build/badge.svg) Decode [Telegram bot API file IDs](https://core.telegram.org). ## Install ```bash composer require danog/tg-file-decoder ``` On 32-bit systems, [phpseclib](https://github.com/phpseclib/phpseclib) is also required. ## Examples: ### Decoding bot API file IDs ```php use danog\Decoder\FileId; use danog\Decoder\UniqueFileId; $fileId = FileId::fromBotAPI('CAACAgQAAxkDAAJEsl44nl3yxPZ8biI8uhaA7rbQceOSAAKtAQACsTisUXvMEbVnTuQkGAQ'); $version = $fileId->getVersion(); // bot API file ID version, usually 4 $subVersion = $fileId->getSubVersion(); // bot API file ID subversion, equivalent to a specific tdlib version $dcId = $fileId->getDcId(); // On which datacenter is this file stored $type = $fileId->getType(); // File type $typeName = $fileId->getTypeName(); // File type (as string) $id = $fileId->getId(); $accessHash = $fileId->getAccessHash(); $fileReference = $fileId->getFileReference(); // File reference, https://core.telegram.org/api/file_reference $url = $fileId->getUrl(); // URL, file IDs with encoded webLocation // You can also use hasFileReference and hasUrl $fileIdReencoded = $fileId->getBotAPI(); // CAACAgQAAxkDAAJEsl44nl3yxPZ8biI8uhaA7rbQceOSAAKtAQACsTisUXvMEbVnTuQkGAQ $fileIdReencoded = (string) $fileId; // CAACAgQAAxkDAAJEsl44nl3yxPZ8biI8uhaA7rbQceOSAAKtAQACsTisUXvMEbVnTuQkGAQ // For photos, thumbnails if ($fileId->getType() <= PHOTO) $volumeId = $fileId->getVolumeID(); $localId = $fileId->getLocalID(); // if $fileId->hasPhotoSizeSource() $photoSizeSource = $fileId->getPhotoSizeSource(); // PhotoSizeSource object $photoSizeSource->getDialogId(); $photoSizeSource->getStickerSetId(); // And more, depending on photosize source ``` The bot API subversion, present since file IDs v4, is equivalent to the [version of tdlib](https://github.com/tdlib/td/blob/master/td/telegram/Version.h#L13) used server-side in the bot API. For file types, see [file types](#bot-api-file-id-types). For photosize source, see [here](#photosize-source). ### Decoding bot API unique file IDs ```php $uniqueFileId = UniqueFileId::fromUniqueBotAPI('AgADrQEAArE4rFE'); $type = $fileId->getType(); // Unique file type $typeName = $fileId->getTypeName(); // Unique file type (as string) $id = $uniqueFileId->getId(); $accessHash = $uniqueFileId->getAccessHash(); $url = $uniqueFileId->getUrl(); // URL, for unique file IDs with encoded webLocation // You can also use hasUrl // For photos $volumeId = $uniqueFileId->getVolumeID(); $localId = $uniqueFileId->getLocalID(); ``` For unique file types, see [unique types](#bot-api-unique-file-id-types). ### Extracting unique file IDs from full file IDs ```php $full = 'CAACAgQAAxkDAAJEsl44nl3yxPZ8biI8uhaA7rbQceOSAAKtAQACsTisUXvMEbVnTuQkGAQ'; $unique = 'AgADrQEAArE4rFE'; $fileId = FileId::fromBotAPI($full); $uniqueFileId = UniqueFileId::fromUniqueBotAPI($unique); $uniqueFileIdExtracted1 = UniqueFileId::fromBotAPI($full); $uniqueFileIdExtracted2 = $fileId->getUniqueBotAPI(); var_dump(((string) $uniqueFileId) === ((string) $uniqueFileIdExtracted1)); // true, always AgADrQEAArE4rFE! var_dump(((string) $uniqueFileId) === ((string) $uniqueFileIdExtracted2)); // true, always AgADrQEAArE4rFE! ``` ### Photosize source ```php $fileId = FileId::fromString('CAACAgQAAxkDAAJEsl44nl3yxPZ8biI8uhaA7rbQceOSAAKtAQACsTisUXvMEbVnTuQkGAQ'); $photoSizeSource = $fileId->getPhotoSizeSource(); // PhotoSizeSource object $sourceType = $photoSizeSource->getType(); // If $sourceType === PHOTOSIZE_SOURCE_DIALOGPHOTO_SMALL|PHOTOSIZE_SOURCE_DIALOGPHOTO_SMALL or // If $photoSizeSource instanceof PhotoSizeSourceDialogPhoto $dialogId = $photoSizeSource->getDialogId(); $dialogId = $photoSizeSource->getStickerSetId(); ``` The `PhotoSizeSource` abstract base class indicates the source of a specific photosize from a chat photo, photo, stickerset thumbnail, file thumbnail. Each photosize type (`getType`) is mapped to a specific subclass of the `PhotoSizeSource` abstract class, returned when calling getPhotoSizeSource. The photosize type is one of: * `const PHOTOSIZE_SOURCE_LEGACY = 0` - Legacy, used for file IDs with the deprecated `secret` field, returns [PhotoSizeSourceLegacy](#photosizesourcelegacy) class. * `const PHOTOSIZE_SOURCE_THUMBNAIL = 1` - Used for document and photo thumbnail, returns [PhotoSizeSourceThumbnail](#photosizesourcethumbnail) class. * `const PHOTOSIZE_SOURCE_DIALOGPHOTO_SMALL = 2` - Used for dialog photos, returns [PhotoSizeSourceDialogPhoto](#photosizesourcedialogphoto) class. * `const PHOTOSIZE_SOURCE_DIALOGPHOTO_BIG = 3` - Used for dialog photos, returns [PhotoSizeSourceDialogPhoto](#photosizesourcedialogphoto) class. * `const PHOTOSIZE_SOURCE_STICKERSET_THUMBNAIL = 4` - Used for document and photo thumbnails, returns [PhotoSizeSourceThumbnail](#photosizesourcethumbnail) class. ### Building custom file IDs ```php $fileId = new FileId; $fileId->setType(STICKER); $fileId->setId($id); $fileId->setAccessHash($customHash); // You get it... $encoded = (string) $fileId; // CAACAgQAAxkDAAJEsl44nl3yxPZ8biI8uhaA7rbQceOSAAKtAQACsTisUXvMEbVnTuQkGAQ, or something ``` All classes, from [FileId](#fileid), to [UniqueFileID](#uniquefileid), to [PhotoSizeSource](PhotoSizeSourceDialogPhoto) can be built using `set` methods for each and every field. ### Bot API file ID types The file type is a numeric constant indicating the type of file, (the constant is always in the `danog\Decoder` namespace). The file type name is a string version of the file type, typically the one used in bot API file objects. The `TYPES` array contains a `file type` => `file type name` map. The `TYPES_IDS` array contains a `file type name` => `file type` map. `const CONSTANTNAME = value` - Description (`type name`) * `const THUMBNAIL = 0` - Thumbnail (`thumbnail`) * `const PROFILE_PHOTO = 1` - Profile photo; used for users, supergroups and channels, chat photos are normal PHOTOs (`profile_photo`) * `const PHOTO = 2` - Photo (`photo`) * `const VOICE = 3` - Voice message (`voice`) * `const VIDEO = 4` - Video (`video`) * `const DOCUMENT = 5` - Document (`document`) * `const ENCRYPTED = 6` - Secret chat document (`encrypted`) * `const TEMP = 7` - Temp document (`temp`) * `const STICKER = 8` - Sticker (`sticker`) * `const AUDIO = 9` - Music (`audio`) * `const ANIMATION = 10` - GIF (`animation`) * `const ENCRYPTED_THUMBNAIL = 11` - Thumbnail of secret chat document (`encrypted_thumbnail`) * `const WALLPAPER = 12` - Wallpaper (`wallpaper`) * `const VIDEO_NOTE = 13` - Round video (`video_note`) * `const SECURE_RAW = 14` - Passport raw file (`secure_raw`) * `const SECURE = 15` - Passport file (`secure`) * `const WALLPAPER = 16` - Background (`background`) * `const WALLPAPER = 17` - Size (`size`) * `const NONE = 18` - ### Bot API unique file ID types The unique file type is a numeric constant indicating the type of the unique file ID, (the constant is always in the `danog\Decoder` namespace). The unique file type name is a string version of the unique file type, typically the one used in bot API file objects. The `UNIQUE_TYPES` array contains a `unique file type` => `unique file type name` map. The `UNIQUE_TYPES_IDS` array contains a `unique file type name` => `unique file type` map. The `FULL_UNIQUE_MAP` array contains a `full file type` => `unique file type` map. * `const UNIQUE_WEB = 0` - Used for web files (all file types that have a URL (`hasUrl`)) * `const UNIQUE_PHOTO = 1` - Used for photos and similar (`getType() <= PHOTO`) * `const UNIQUE_DOCUMENT = 2` - Used for all other types of files (documents, audio, video, voice, sticker, animation, video note) * `const UNIQUE_SECURE = 3` - Used for passport files * `const UNIQUE_ENCRYPTED = 4` - Used for secret chat files * `const UNIQUE_TEMP = 5` - Used for temp files ##
