How can the issue of displaying a "0" in the frontend when no image is uploaded for a field be addressed in PHP code?

When no image is uploaded for a field in the frontend, the PHP code can be modified to display a placeholder image or a "0" to indicate that no image is present. This can be achieved by checking if the image file exists in the specified directory and displaying either the image or the "0" accordingly. 

<?php
$image_path = 'path/to/image.jpg';

if (file_exists($image_path)) {
    echo '<img src="' . $image_path . '" alt="Image">';
} else {
    echo '0';
}
?>
