Are there any recommended solutions for keeping a connection open between a PHP webpage and a Python server?

To keep a connection open between a PHP webpage and a Python server, one recommended solution is to use a technique called long polling. This involves the PHP webpage making a request to the Python server, which holds the connection open until it has new data to send back. This allows for real-time communication between the two. 

<?php
$pythonServerUrl = 'http://localhost:8000'; // Replace this with your Python server URL

while (true) {
    $data = file_get_contents($pythonServerUrl);
    
    if ($data) {
        echo $data;
        break;
    }
    
    sleep(1); // Adjust the sleep time as needed
}
?>
