Why telegram bot doesn't respond to messages in channel?

[patzu]

I have created a channel in telegram and I added a bot as an administrator of the channel, when I send a message to channel the bot doesn't answer, why?

I can send a message with /sendmessage

https://api.telegram.org/bot[key]/sendmessage?chat_id=@MyChannelID&text=This text is from bot to channel.

In the code below when I send a text " call " nothing happens.

<?php 

 include 'connection.php';
 include("Telegram.php");
 define('bot_id', 'key');
 $telegram = new Telegram(bot_id);

 $text = $telegram->Text();
 $chat_id = $telegram->ChatID();

 if ($text == "call") {
 $content = array('chat_id' => $chat_id, 'text' => "This is test     message!!!");
 $telegram->sendMessage($content);   
  }

 ?>

Thank you my friend for your patience in answering my questions.

for sending a message in a channel i use this:

if ($text == "/channel") {
    $reply = "Chat id " . $chat_id;
    $chat_id = "@testmiobot";
    $content = array('chat_id' => $chat_id, 'text' => $reply);
    $telegram->sendMessage($content);
}

BTW the bot don't respond to messages sended in a channel, could be a bug

Do you know where should we use this code?

curl has this problem for SSL. add this code to Solve problem :
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);

it's already present.
You could try to log what telegram send to the bot when someone sends a message on the channel.
