How can the folder name in which a specific file is located be analyzed in PHP?

To analyze the folder name in which a specific file is located in PHP, you can use the `dirname()` function to extract the directory path of the file and then use `basename()` function to get the folder name from the path.

$file_path = '/path/to/your/file.txt';
$folder_name = basename(dirname($file_path));
echo $folder_name;
