What is the potential issue with using the sleep() function in PHP to delay a chatbot response in an Ajax chat system?

Using the sleep() function in PHP to delay a chatbot response in an Ajax chat system can cause the entire script to pause, affecting the responsiveness of the chat system. To solve this issue, you can use asynchronous processing techniques like setting a timer in JavaScript to delay the chatbot response without blocking the execution of the script. 

<?php
// Simulate a delay of 3 seconds before sending a response
usleep(3000000); // Sleep for 3 seconds (in microseconds)

// Send the response
echo json_encode(['message' => 'Hello, how can I help you?']);
?>
