How can I use a rasa chatbot on my own website?

Rasa Open Source
1

I’m new to Rasa, I have trained a bot locally and I would like to deploy it to my website. Just using PHP and nothing else, no docker, no nodejs, nothing else. I have a simple UI and so far I can call the chatbot via this function:

function processInputText($inptext)
{
    //Send inptext to rasa-nlu http server and obtain the processed result.
    $rasatext = file_get_contents("http://url.com/chatbot/model?q=" . urlencode($inptext));
    //Decode the response text as a json array
    $rasajson = json_decode($rasatext, true);
    
    //Extract the intent
    $rasa_intent = !empty($rasajson["topScoringIntent"]["intent"]) ? $rasajson["topScoringIntent"]["intent"] : '';
    
    //Extract the entities
    $rasa_entities = '';
    if(!empty($rasajson["entities"]))
        {
        foreach ($rasajson["entities"] as $entity)
            {
            $rasa_entities = $rasa_entities . $entity["type"] . '=>' . $entity["entity"] . "<br>";
            }
        }
    //Prepare a reponse text.    
    return '<b>Message: </b> ' . $inptext  . '<br><b>Intent:</b> ' . $rasa_intent . '<br><b>Entities:</b><br>' . $rasa_entities;    
}

However, no matter what I look I always find a way to deploy using something like docker or sockets or the like. Could anybody help me?

I don’t know if I need to deploy only the model or do something else and then put that online or what to do…

My folder structure is as follows:

/
├── chatbot
│       ├── assets
│       ├──  chatbot.js
│       └──  chatbot.css
├── chatbot.html  
└── chatservice.php

I use my js to call the PHP which would then handle the call to the chatbot but no idea what I need to add there so it works. This happens by doing a simple AJAX call:

$.ajax({
          url: './chatservice.php',
          type: 'POST',
          dataType: 'json',
          contentType: 'application/json',
          data: JSON.stringify({"msg":text}),
          success: function (response) 
              {
              //console.log(response.text);
              insertChat("you", response.text); 
              },
          error: function () 
            {
            insertChat("you", "error"); 
            }          
     });

Which then inside the PHP file does:

function processInputText($inptext)
{
    //Send inptext to rasa-nlu http server and obtain the processed result.
    $rasatext = file_get_contents("http://url.com/chatbot/model?q=" . urlencode($inptext));
    //Decode the response text as a json array
    $rasajson = json_decode($rasatext, true);
.
.
.
}

It is here that I don’t know if I should upload the model or how can I get it to properly respond.
