19.12. Removing a Directory and Its Contents
On Unix, use rm:
$directory = escapeshellarg($directory); exec("rm -rf $directory");
On Windows, use rmdir:
$directory = escapeshellarg($directory); exec("rmdir /s /q $directory");
Because PHP's built-in directory removal function, rmdir( ) , works only on empty directories, and unlink( ) can't accept shell wildcards, calling a system program is much easier than recursively looping through all files in a directory, removing them, and then removing each directory. If an external utility isn't available, however, you can modify the pc_process_dir( ) function from Recipe 19.10 to remove each subdirectory.
