README
A library to work with Telegram UTF-16 styled text entities, created by Daniil Gentili (https://daniil.it).
This library can be used to modify entities returned by the Telegram Bot API, convert entities to HTML or even locally generate them using a custom MarkdownV2 and HTML parser inside of the library.
This library was initially created for MadelineProto, an async PHP client API for the telegram MTProto protocol.
Installation
composer require danog/telegram-entities
Usage
<?php declare(strict_types=1); use Amp\Http\Client\HttpClientBuilder; use Amp\Http\Client\Request; use danog\TelegramEntities\Entities; use danog\TelegramEntities\EntityTools; require __DIR__.'/../vendor/autoload.php'; $token = getenv('TOKEN'); if (!$token) { throw new AssertionError("A TOKEN environment variable must be specified!"); } $dest = getenv('DEST'); if (!$dest) { throw new AssertionError("A DEST environment variable must be specified!"); } $client = HttpClientBuilder::buildDefault(); $sm = function (string $message, string $parse_mode = '', array $entities = []) use ($token, $dest, $client): array { $res = $client->request(new Request("https://api.telegram.org/bot$token/sendMessage?".http_build_query([ 'text' => $message, 'parse_mode' => $parse_mode, 'entities' => json_encode($entities), 'chat_id' => $dest ]))); return json_decode($res->getBody()->buffer(), true)['result']; }; $result = $sm("*This is a ❤️ test*", parse_mode: "MarkdownV2"); // Convert a message+entities back to HTML $entities = new Entities($result['text'], $result['entities']); var_dump($entities->toHTML()); // <b>This is a ❤️ test</b> // Modify $entities as needed $entities->message = "A message with ❤️ emojis"; // EntityTools::mb* methods compute the length in UTF-16 code units, as required by the bot API. $entities->entities[0]['length'] = EntityTools::mbStrlen($entities->message); // then resend: $sm($entities->message, entities: $entities->entities); // Convert HTML to an array of entities locally $entities = Entities::fromHtml("<b>This is <i>a ❤️ nested</i> test</b>"); $sm($entities->message, entities: $entities->entities); // Convert markdown to an array of entities locally $entities = Entities::fromMarkdown("*This is _a ❤️ nested_ test*"); $sm($entities->message, entities: $entities->entities); // Escape text using utility methods $generic = EntityTools::markdownEscape("Automatically escaped to prevent *markdown injection*!"); $link = EntityTools::markdownUrlEscape("https://google.com"); $code = EntityTools::markdownCodeEscape("test with autoescaped ` test"); $codeBlock = EntityTools::markdownCodeblockEscape("<?php echo 'test with autoescaped ``` test';"); $entities = Entities::fromMarkdown("This is _a ❤️ [nested]($link)_ `$code` \```php $codeBlock \``` $generic "); $sm($entities->message, entities: $entities->entities); // Escape text for the HTML parser! $generic = EntityTools::htmlEscape("Automatically escaped to prevent <b>HTML injection</b>!"); $entities = Entities::fromHtml($generic); $sm($entities->message, entities: $entities->entities); // See https://github.com/danog/telegram-entities for the full list of available methods!
