What is the difference between client-side and server-side image swapping in PHP?

Client-side image swapping refers to changing an image displayed on a webpage using JavaScript or CSS, without involving the server. Server-side image swapping involves changing the image on the server-side using PHP and then serving the updated image to the client. To implement server-side image swapping in PHP, you can use a conditional statement to determine which image to display based on certain conditions. You can dynamically generate the image source URL in the HTML code based on the condition. 

<?php
// Assuming $condition is a variable that determines which image to display
if ($condition) {
    $imageSrc = "image1.jpg";
} else {
    $imageSrc = "image2.jpg";
}
?>

<img src="<?php echo $imageSrc; ?>" alt="Image">
