This article explains the Linux Filesystem Hierarchy Standard (FHS), describes the purpose and typical contents of each top‑level directory such as /home, /boot, /etc, /usr, and /var, and demonstrates essential shell commands for navigating and managing these directories, including absolute and relative paths.
The PHP scandir function returns an array of filenames and sub‑directories from a given directory, optionally sorted in ascending or descending order, and can accept a stream context, providing FALSE on failure and generating a warning if the path is not a directory.
This article explains PHP's opendir function, which opens a directory handle for subsequent closedir, readdir, and rewinddir operations, details its parameters and return values, and provides a complete example script demonstrating how to read directory contents and output file names with their types.
The article explains the PHP getcwd() function, its return values, permission considerations on Unix variants, and provides a clear code example demonstrating how to obtain and change the current working directory using echo and chdir.
The article explains PHP's dir() function, detailing its parameters, return values, and providing a complete example that demonstrates opening a directory, retrieving its handle and path, iterating over entries, and closing the directory resource.
The PHP closedir function closes a directory handle opened by opendir, accepting a resource parameter and returning TRUE on success or FALSE on failure, with usage examples and parameter details for backend filesystem operations.
