How can PHP developers optimize the organization of files and directories to avoid redundancy and improve efficiency in managing resources like images and configuration files?

To optimize the organization of files and directories in PHP, developers can create a clear folder structure that separates different types of files such as images, configuration files, and scripts. By organizing files logically, developers can avoid redundancy and improve efficiency in managing resources. Additionally, using relative paths instead of absolute paths can make it easier to move files around without breaking links.

// Example of organizing files and directories in PHP

// Define constants for file paths
define('ROOT_PATH', __DIR__);
define('IMAGE_PATH', ROOT_PATH . '/images');
define('CONFIG_PATH', ROOT_PATH . '/config');

// Load configuration file
$config = require(CONFIG_PATH . '/config.php');

// Display an image
echo '<img src="' . IMAGE_PATH . '/example.jpg" alt="Example Image">';
