Example of method of creating multi-level directories and cascading delete files

This article describes the method of creating multi-level directories and cascading delete files in PHP. Share it for your reference, as follows:

Create multi-level directory

mkdirFunctions can only create first-level directories. If we want to create multi-level directories, we need to write the functions ourselves.

<?php
$path = "one/two/three/four";
function mkdir_p($path,$mode=0700){
  $arr = explode("/",$path);
  $path = '';
  foreach($arr as $v){
    $path .= $v;
    mkdir($path,$mode);
    $path .= "/";
  }
}
mkdir_p($path);

Delete files in cascading

We know PHPrmdirFunctions can only delete empty folders.unlinkOnly used to delete files.

We can write functions ourselves and delete non-empty folders cascaded.

<?php
$path = $_SERVER['DOCUMENT_ROOT']."lib";
function rmdir_r($path){
  $handle = opendir($path);
  while($file=readdir($handle)){  //Delete all folders    $type = filetype($path."/".$file);
    if($file=='.'||$file=="..")
      continue;
    if($type=="file"){
      //If the type is file, delete it      unlink($path."/".$file);
    }
    if($type=="dir"){
      //If the type is a folder, then cascadingly delete      rmdir_r($path."/".$file);
    }
  }
  closedir($handle);
  rmdir($path);
}
rmdir_r($path);
