In what situations should the get_message() function be called in a PHP bot script to ensure smooth message processing without blocking the script?

When building a PHP bot script, the get_message() function should be called asynchronously to ensure smooth message processing without blocking the script. This can be achieved by utilizing AJAX requests to fetch new messages from the bot's messaging platform in the background, allowing the script to continue running without waiting for new messages.

// Example implementation using AJAX to fetch messages asynchronously

// Function to fetch new messages from the bot's messaging platform
function get_message() {
    // Code to fetch new messages goes here
}

// AJAX request to periodically fetch new messages
setInterval(function() {
    $.ajax({
        url: 'get_message.php',
        method: 'GET',
        success: function(response) {
            // Process the new message received
            console.log(response);
        },
        error: function(xhr, status, error) {
            console.error(error);
        }
    });
}, 1000); // Fetch new messages every 1 second
