title: How to use ForceReply in a telegram bot
body: <p>I'm developing a telegram bot using php and a web hook. All it's fine but sometimes I would like to "wait for a reply" from the user. For example:</p>
  
  <p>If the client write /info without any parameters I would like to show a "usage" message and ask&amp;wait for a ID parameter.</p>
  
  <p>I know there is a property "ForceReply" to force for a reply, but when I set it up nothing happens, and I don't know how to know if the client message its a reply for my question. </p>
  
  <p>Do I have to put my php server on hold? (I think it would be a bad practice) Do I have to whait for a type of message?</p>
  
  <p>Thanks</p>
