How can symbolic links be used to resolve file path issues when displaying images in PHP on a Raspberry Pi web server?

When displaying images in PHP on a Raspberry Pi web server, file path issues may arise due to the server's file structure. Symbolic links can be used to create a virtual path that points to the actual location of the image files, resolving any path discrepancies. This allows PHP to correctly access and display the images on the web page. 

<?php
// Define the symbolic link path to the image directory
$symbolicLink = '/var/www/html/images';
$actualPath = '/home/pi/images';

// Create a symbolic link
symlink($actualPath, $symbolicLink);

// Use the symbolic link path to display the image
$imagePath = '/images/example.jpg';
echo '<img src="' . $imagePath . '" alt="Example image">';
?>
