What are the steps to properly integrate jQuery for AJAX functionality in a PHP and JavaScript project?

To properly integrate jQuery for AJAX functionality in a PHP and JavaScript project, you need to include the jQuery library in your project, write JavaScript code to make AJAX requests to your PHP backend, and handle the response data in your front-end code. 

```php
<!DOCTYPE html>
<html>
<head>
    <title>AJAX Example</title>
    <script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>
</head>
<body>

<button id="ajaxButton">Click me to make an AJAX request</button>
<div id="response"></div>

<script>
    $(document).ready(function(){
        $('#ajaxButton').click(function(){
            $.ajax({
                url: 'ajax.php',
                type: 'GET',
                success: function(response){
                    $('#response').html(response);
                },
                error: function(){
                    $('#response').html('Error occurred');
                }
            });
        });
    });
</script>

</body>
</html>
```

In this example, we include the jQuery library in the head section of our HTML file. We then write JavaScript code to make an AJAX GET request to a PHP file named "ajax.php" when a button is clicked. The response data from the PHP file is displayed in a div element with the id "response".
