How to delete an empty directory and a null directory from PHP

Steps:

1. Traverse Directory and subdirectories

2. Use Scandir to determine whether the directory is empty, empty, and use rmdir to delete it.

<?php  
/** Delete all empty directory 
* @param String $path directory path 
/
function Rm_empty_dir ($path) {  
    if Is_dir ($path ) && ($handle = Opendir ($path))!==false {while  
        ($file =readdir ($handle))!==false) {     //Traverse folder  
            if ( $file!= '. ' && $file!= '. ') {  
                $curfile = $path. ' /'. $file;          Current directory  
                if (Is_dir ($curfile)) {                //directory  
                    Rm_empty_dir ($curfile);          If the directory continues to traverse if  
                    (count (Scandir ($curfile)) ==2) {//directory is empty, =2 is because. Existence of  
                        rmdir ($curfile);             Delete Empty Directory  
                    }}}  
        closedir ($handle);  
      
} $folder = ' destination folder ';  
      
Rm_empty_dir ($folder);

Using a shell is a lot simpler:

Find target folder-mindepth 1-depth-empty-type d-exec rm-r {} \;
