Sure, here is an example of how you could implement this using PHP and CSS:

1. First, create a PHP file that includes the time information. This file can use the current time to determine which portion of the day (morning, day, evening, night) it is. Here is an example of how this could be implemented:
```php
<?php

$datetime = new DateTime();
$hour = $datetime->format("H");

if ($hour >= 6 && $hour <= 12) {
    $time = "morning";
}else if ($hour >= 12 && $hour <= 17) {
    $time = "day";
}else if ($hour >= 17 && $hour <= 20) {
    $time = "evening";
}else if ($hour >= 20 && $hour <= 6) {
    $time = "night";
}

?>
```
2. Next, create a CSS file that defines the different styles for the sun based on the time of day. Here is an example of how this could be implemented:
```css
.sun-morning {
    background-color: yellow;
    border-radius: 100%;
}

.sun-day {
    background-color: yellow;
    border-radius: 100%;
}

.sun-evening {
    background-color: orange;
    background-image: linear-gradient(to right bottom, #dd2900, #da6c0e);
    border-radius: 100%;
}

.sun-night {
    background-color: red;
    border-radius: 100%;
}
```
3. In the HTML file, use CSS classes to apply the styles based on the time of day. Here is an example of how this could be implemented:
```html
<div class="sun-<?php echo $time;?>"></div>
```
In this example, the PHP variable `$time` is used to select the appropriate CSS class, which determines the appearance of the sun.

4. Finally, you can use JavaScript to request the current time from the user's device and update the styles accordingly. Here is an example of how this could be implemented using jQuery:
```javascript
setInterval(function() {
    $.get("time.php", function(data) {
        var hour = data.match(/\d+/)[0];
        if (hour >= 6 && hour <= 12) {
            $(".sun").removeClass("sun-evening sun-night").addClass("sun-morning");
        }else if (hour >= 12 && hour <= 17) {
            $(".sun").removeClass("sun-morning sun-evening").addClass("sun-day");
        }else if (hour >= 17 && hour <= 20) {
            $(".sun").removeClass("sun-day sun-night").addClass("sun-evening");
        }else if (hour >= 20 && hour <= 6) {
            $(".sun").removeClass("sun-morning sun-day sun-evening").addClass("sun-night");
        }
    });
}, 1000);
```
This script requests the current time from the server every second and updates the CSS classes accordingly. The `time.php` file is the same file we created in step 1, which determines the time of day based on the current hour.

I hope this helps! Let me know if you have any further questions.

To create a dynamic webpage that changes the appearance of a sun based on the time of day using PHP and CSS, you'll need to follow these high-level steps:

1. Determine the current time: You'll need to use PHP's built-in `date()` function to get the current time in the desired timezone.

2. Calculate the sun's position: To determine the sun's appearance (daytime vs. Sunset), you'll need to calculate the sun's position based on the current time and the user's location. You can use a third-party API like OpenWeatherMap or NASA's Astronomy API to retrieve this information.

3. Generate CSS classes based on the sun's position: Once you have the sun's position, you'll need to create CSS classes that define the different styles for the sun based on the time of day. For example, you might have classes like `sun-daytime`, `sun-sunset`, and `sun-nighttime`.

4. Use PHP to dynamically set the CSS class: In your HTML, create a container element for the sun (e.g., `<div class="sun"></div>`) and use PHP to set the appropriate CSS class based on the sun's position.

Here's a basic example of how you might implement this using PHP and CSS:

1. First, create a PHP script (e.g., `sun_display.php`) that retrieves the current time and calculates the sun's position. For simplicity, let's assume you're using the OpenWeatherMap API and the user's location is set to New York City (replace `<YOUR_API_KEY>` with your actual API key):

```php
<?php

// OpenWeatherMap API endpoint
$api_url = 'https://api.openweathermap.org/data/2.5/onecall';
$api_key = '<YOUR_API_KEY>';
$city_id = '4517178'; // New York City ID

// Get current time in UTC
$current_time = date('U');

// API request
$url = "$api_url?lat=40.7128&lon=-74.0060&exclude=minutely,hourly,alerts&appid=$api_key&units=metric";
$response = file_get_contents($url);
$data = json_decode($response, true);

// Calculate sunrise and sunset times
$sunrise_time = $data['current']['sunrise'];
$sunset_time = $data['current']['sunset'];

// Calculate current hour (in UTC)
$current_hour = date('H', $current_time);

// Define CSS classes based on sun's position
$sun_class = 'sun-daytime';
if ($current_hour >= $sunset_time['hour'] || $current_hour < $sunrise_time['hour']) {
    $sun_class = 'sun-nighttime';
} elseif ($current_hour >= $sunrise_time['hour'] && $current_hour < $sunset_time['hour']) {
    $sun_class = 'sun-sunset';
}

?>
```

2. In your HTML file, include the PHP script and create a container element for the sun:

```html
<!DOCTYPE html>
<html>
<head>
    <title>Dynamic Sun Display</title>
    <style>
        /* CSS styles for sun */
        .sun {
            width: 50px;
            height: 50px;
            border-radius: 50%;
            background-color: #ffcc00; /* default daytime color */
            transition: background-color 0.5s ease;
        }

        .sun-daytime {
            background-color: #ffcc00;
        }

        .sun-sunset {
            background-image: radial-gradient(circle at center, #ff7f00, #ff4500);
        }

        .sun-nighttime {
            background-color: #ff0000;
        }
    </style>
</head>
<body>
    <?php include 'sun_display.php'; ?>
    <div class="sun" id="sun"></div>
</body>
</html>

Sure, here is a sample code for how to implement this using PHP and CSS:

```php
<?php
$time = date("H:i:s");
$is_daytime = ($time >= 6 && $time <= 18);

if ($is_daytime) {
  // Set the sun to a bright yellow circle
  $sun_color = "yellow";
} else {
  // Set the sun to a red and orange swirl
  $sun_color = "red orange";
}

?>

<!DOCTYPE html>
<html>
<head>
  <title>Dynamic Sun</title>
  <style>
    body {
      background-image: url("https://picsum.photos/id/100/200/200");
    }

    #sun {
      width: 100px;
      height: 100px;
      position: absolute;
      top: 50px;
      left: 50px;
      background-color: <?php echo $sun_color; ?>;
    }
  </style>
</head>
<body>
  <div id="sun"></div>
</body>
</html>
```

This code will create a dynamic webpage that changes the appearance of the sun based on the time of day. The sun will be a bright yellow circle during the day, but a red and orange swirl during sunset.
