如何从PHP上的python脚本获取实时输入输出

Question

I want to take input from user through a html form, process it through a python script and print the output on html page. The problem is the whole python script is executed each time, while I want the script to give real time output for each input. How can I manage to do this ?

Here is what I am doing so far.

<?php
    $vout='';
    if(isset($_POST['submit']))
    {
        $vin=$_POST['input_text'];
        $vout=exec('python bot.py '.$vin);
    }
?>
<form method="post">
<label>
    BotIn: <input type="text" name="input_text">
</label>
<input type="submit" name="submit">
</form>
</br></br>
<label>
    <p>Bot: <?=$vout?></p>
</label>

The best way to solve your problem will be running simple python app using, let's say, Flask and hit to specific endpoint you'll make in it. Everything then could take place through localhost, if you'll set it on the same machine.
