What are the potential pitfalls of relying solely on PHP for time-controlled image updates?

Potential pitfalls of relying solely on PHP for time-controlled image updates include server-side processing limitations, potential delays in image updates due to server performance issues, and the inability to update images in real-time. To mitigate these issues, consider implementing a combination of client-side and server-side solutions, such as utilizing JavaScript for real-time updates and PHP for backend processing. 

// Example of using JavaScript for real-time image updates in combination with PHP
<?php
// PHP code to retrieve image file path
$imagePath = "path/to/image.jpg";
?>

<!DOCTYPE html>
<html>
<head>
    <title>Time-controlled Image Updates</title>
    <script>
        function updateImage() {
            var imagePath = "<?php echo $imagePath; ?>";
            var timestamp = new Date().getTime();
            var imageUrl = imagePath + "?timestamp=" + timestamp;
            document.getElementById("image").src = imageUrl;
        }

        setInterval(updateImage, 5000); // Update image every 5 seconds
    </script>
</head>
<body>
    <img id="image" src="<?php echo $imagePath; ?>" alt="Image">
</body>
</html>
