PHP Directory Operation example Summary _php skill

This article summarizes the PHP directory operation method. Share to everyone for your reference, specific as follows:

Directory Operations

new directory : mkdir (path, permissions, recursive creation)

Delete directory : RmDir ()

Mobile (renamed): rename ()

Get directory Contents :

Open Directory

Directory handle = Opendir ()

Reading directories

filename = readdir (directory handle)

Read the file name in turn, move the handle pointer down, and return false when it is not read

Close Directory

Closedir ()

Recursively read Directory contents:

<?php
Showdir ('.. /.. /file ');
function Showdir ($path, $dep =0) {
 $pos = Opendir ($path);
 while (false!== $file =readdir ($pos)) {
  if ($file = = '. ') $file = = '.. ') Continue;
  echo str_repeat ("", $dep *4), $file. ' </br> ';
  if (Is_dir ($path. ') /'. $file)) {
   $func = __function__;
   $func ($path. ' /'. $file, $DEP + 1);}}

The Operation effect chart is as follows:

<?php
$res = Showdir ('.. /.. /file ');
Echo ' <pre> ';
Print_r ($res);
function Showdir ($path) {
 $pos = Opendir ($path);
 $next = Array ();
 while (false!== $file =readdir ($pos)) {
  if ($file = = '. ') $file = = '.. ') Continue;
  $fileinfo = Array ();
  $fileinfo [' name '] = $file;
  if (Is_dir ($path. ') /'. $file)) {
   $fileinfo [' type '] = ' dir ';
   $func = __function__;
   $fileinfo [' next '] = $func ($path. ') /'. $file);
  } else{
   $fileinfo [' type '] = ' file ';
  }
  $next [] = $fileinfo;
 }
 Closedir ($pos);
 return $next;
}

The Operation effect chart is as follows:

To delete a directory recursively:

<?php
Showdir ('.. /.. /file/sim ');
function Showdir ($path, $dep =0) {
 $pos = Opendir ($path);
 while (false!== $file =readdir ($pos)) {
  if ($file = = '. ') $file = = '.. ') Continue;  Echo Str_repeat ("", $dep *4), $file. ' </br> ';
  if (Is_dir ($path. ') /'. $file)) {
   $func = __function__;
   $func ($path. ' /'. $file, $DEP + 1);
  } else{
   unlink ($path. ' /'. $file);
  }
 RmDir ($path);
 Closedir ($pos);

Directory file Encoding problem:

When presented, converts the operating system code into a response data encoding

Windows for GBK, Project Utf-8

Iconv (' GBK ', Utf-8 ', file);

Code address in Chinese: need to convert to system encoding

Iconv (Utf-8 ', ' GBK ', file);
