How does php delete the current folder?

PHP deletes all files in the current directory and its directory

Use PHP to traverse all directories and files under a directory, and delete all subdirectories and files under the directory. This code is realized by recursion.

Functions used:

Scandir ($path) iterates through all the files in a directory and returns an array.

Unlink ($filename) deletes the file.

Rmdir ($path) deletes only empty folders.

PHP Code:

/ * delete all directories and files under the current directory and its directory * @ param string $path directories to be deleted * @ note $path path without slashes / (for example: correct [$path='./linuxidc/image'] Error [$path='./linuxidc/image/']) * / function deleteDir ($path) {if (is_dir ($path)) {/ / scan all directories and files in a directory and return the array $dirs = scandir ($path) Foreach ($dirs as $dir) {/ / exclude the current directory (.) And the next level directory (..) If ($dir! ='.'& & $dir! ='..') {/ / Recursive subdirectories if it is a directory, continue with $sonDir = $path.'/'.$dir; if (is_dir ($sonDir)) {/ / Recursively delete deleteDir ($sonDir) / / delete the empty directory @ rmdir ($sonDir) after deleting the subdirectories and files in the directory;} else {/ / if the files are deleted directly @ unlink ($sonDir);} @ rmdir ($path);}}
