[Python] Running Python on a webserver using PHP

I'm using a PHP script to execute a Python script on a localhost XAMPP web server:

<?php
$python_path = 'C:\Users\alona\AppData\Local\Programs\Python\Python39\python.exe';
$output = shell_exec($python_path . ' my_script.py');
echo $output;
?>


When the Python script contains simple output like print("Hi"), the PHP code executes the Python program and displays the output correctly.

However, with a more complex Python code like this:

import pytz
from datetime import datetime

city = input("What country do you live in? ")
timezone = pytz.timezone(city)

current_time = datetime.now(timezone)
print("The time in your country is:", current_time.strftime("%H:%M:%S"))


The PHP page only shows "What's your country?" without allowing the user to input their country or displaying the second output. The PHP script should function like a command line, but on a web page. So, just like running python my_script.py on my computer prompts: "What country do you live in?" and after inputting "Canada" it shows "The time in your country is: 09:52:06". The same functionality should be achieved with my PHP script.
