What is MyWeatherTodayBot?

MyWeatherTodayBot is a Telegram Bot that’s able to send your location and get real time weather forecast.

How MyWeatherTodayBot made?

MyWeatherTodayBot is made by PHP and a web service to get weather forecast. First it receives user input as location (latitude and longitude), and the bot will send a REST POST to an external web service to get weather forecast.

To make your own MyWeatherTodayBot, you need Telegram Apps, and Invited @BotFather (a Telegram own bot that you can create your bot) to your accounts, that you can get started to create bot.

Step by Step to create MyWeatherTodayBot

  1. Chat with @BotFather
  2. Click and send /newbot
  3. Name your bot
  4. Copy the API token and it looks like this: 898795721:AAGkiU2Taw83m6CDpVSpH4PaVbEaFkIByHo
  5. Write a PHP file and hosts on a web server, assume the location of the file is at https://<your web server>/bot/telegrambot.php
  6. With following code
[code] $endpoint = ''; $action = !empty($_GET['action']) ? $_GET['action']:''; function reply($chat_id, $text, $opts = array()) { global $endpoint; $url = $endpoint . ‘/sendMessage?text=’.urlencode($text) . ‘&chat_id=’.$chat_id; if(!empty($opts[‘reply_markup’])) { $url .= ‘&reply_markup=’ . json_encode($opts[‘reply_markup’]); } if(!empty($opts[‘parse_mode’])) { $url .= ‘&parse_mode=’ . urlencode($opts[‘parse_mode’]); } file_get_contents($url); } if($action == ‘setWebhook’) { $url = ‘https://<your web server>/bot/telegrambot.php?action=incoming’; echo file_get_contents($endpoint.’/setWebhook?url=’.urlencode($url)); } else if($action == ‘info’) { echo file_get_contents($endpoint.’/getMe’); } else if($action == ‘incoming’) { $entityBody = file_get_contents(‘php://input’); $incoming = json_decode($entityBody, true); $username = $incoming[‘message’][‘from’][‘username’]; $chatid = $incoming[‘message’][‘from’][‘id’]; $input = $incoming[‘message’][‘text’]; $location = $incoming[‘message’][‘location’]; if(!empty($location)) { $latitude = $location[‘latitude’]; $longitude = $location[‘longitude’]; $userData[‘weather’][‘latitude’] = $latitude; $userData[‘weather’][‘longitude’] = $longitude; $url = “,lat=$latitude,lng=$longitude,display=label,stat=telegrambot”; $label = file_get_contents($url); reply($chatid, $label); } else { reply($chatid, ‘Enter your location to get weather now’, array( ‘reply_markup’ => array( ‘one_time_keyboard’ => true, ‘keyboard’ => array( array( array(‘text’ => ‘My Location’,’request_location’ => true) ) ) ) )); } } [/code]
