How to List Folders, Subfolders, and Files in a Directory Using PHP

In PHP, listing the contents of a directory, including subdirectories and files, is a common task. For a hierarchical directory structure like the one provided, it's crucial to consider how to efficiently obtain a complete list of all files and subfolders.

One method for achieving this is to use PHP's scandir() function. However, this function only lists the immediate children of the specified directory, not its subdirectories. To recursively list all the files and subdirectories, a recursive function is employed.

The provided PHP solution utilizes a recursive function called listFolderFiles() that takes a directory path as its input. Within this function, the scandir() function is used to list the contents of the given directory, excluding "." (current directory) and ".." (parent directory).

The function then iterates through the listed files and subdirectories, and for each subdirectory, it recursively calls itself to list its contents. This ensures that all subdirectories are explored and their files listed.

The results are displayed as an ordered list using HTML, where each list item represents a file or subdirectory within the directory. This provides a clear and hierarchical view of the file and directory structure.

This approach effectively captures the hierarchical structure of the directories and subdirectories, ensuring that all files are listed comprehensively. It's a practical solution for managing and navigating complex file structures and displaying their contents in a user-friendly format.
