$ PathDir = $ pathFile = array ();
$ Count = count ($ fileAll );
 
If ($ count <= 2 ){
Echo "empty directory <br/> ";
    }
     
Foreach ($ fileAll as $ pdf ){
If (is_dir ($ dir. $ pdf )){
$ PathDir [] = $ pdf;
} Else {
$ PathFile [] = $ pdf;
        }
    }
 
Foreach ($ pathDir as $ pd ){
If ($ pd = '.' or $ pd = '..') continue;
Echo "<a href = "? Url = $ dir $ pd "> $ pd </a> <br/> ";

Echo "<a href =" $ dir $ pf "target =" _ blank "> $ pf </a> <br/> ";
    }
 
If ($ dir! = './'){
$ Dir = rtrim ($ dir ,'/');
$ Dir = explode ('/', $ dir );
Unset ($ dir [sizeof ($ dir)-1]);
$ Dir = implode ('/', $ dir );

<? Php

/**

* GetDir () is used to go to the folder list, and getFile () is used to go to the file list under the corresponding folder. The difference between the two is to determine whether there are files with the "." suffix, and the others are the same.
*/

// Obtain the file directory list. This method returns an array.
Function getDir ($ dir ){
$ DirArray [] = NULL;
If (false! = ($ Handle = opendir ($ dir ))){
$ I = 0;
While (false! ==( $ File = readdir ($ handle ))){
// Remove "". "," .. ", and files with the suffix". xxx"
If ($ file! = "." & $ File! = ".."&&! Strpos ($ file ,".")){
$ DirArray [$ I] = $ file;
$ I ++;
   }
  }
// Close the handle
Closedir ($ handle );
 }
Return $ dirArray;
}

// Obtain the file list
Function getFile ($ dir ){
$ FileArray [] = NULL;
If (false! = ($ Handle = opendir ($ dir ))){
$ I = 0;
While (false! ==( $ File = readdir ($ handle ))){
// Remove "". "," .. ", and files with the suffix". xxx"
If ($ file! = "." & $ File! = ".." & Strpos ($ file ,".")){
$ FileArray [$ I] = "./imageroot/current/". $ file;
If ($ I == 100 ){

    }
$ I ++;
   }
  }
// Close the handle
Closedir ($ handle );

// Call the getDir ("./dir ")...... It can be an absolute or relative path.
