Listing all the folders subfolders and files in a

Question

Please give me a solution for listing all the folders,subfolders,files in a directory using php. My folder structure is like this:

Main Dir
 Dir1
  SubDir1
   File1
   File2
  SubDir2
   File3
   File4
 Dir2
  SubDir3
   File5
   File6
  SubDir4
   File7
   File8

I want to get the list of all the files inside each folder.

Is there any shell script command in php?

Answer 1

A very simple way to show folder structure makes use of RecursiveTreeIterator class (PHP 5 >= 5.3.0, PHP 7) and generates an ASCII graphic tree.

$it = new RecursiveTreeIterator(new RecursiveDirectoryIterator("/path/to/dir", RecursiveDirectoryIterator::SKIP_DOTS));
foreach($it as $path) {
  echo $path."<br>";
}

http://php.net/manual/en/class.recursivetreeiterator.php

There is also some control over the ASCII representation of the tree by changing the prefixes using RecursiveTreeIterator::setPrefixPart, for example $it->setPrefixPart(RecursiveTreeIterator::PREFIX_LEFT, "|");

Answer 2

In case you want to use directoryIterator

Following function is a re-implementation of @Shef answer with directoryIterator

function listFolderFiles($dir)
{
    echo '<ol>';
    foreach (new DirectoryIterator($dir) as $fileInfo) {
        if (!$fileInfo->isDot()) {
            echo '<li>' . $fileInfo->getFilename();
            if ($fileInfo->isDir()) {
                listFolderFiles($fileInfo->getPathname());
            }
            echo '</li>';
        }
    }
    echo '</ol>';
}
listFolderFiles('Main Dir');

You can also try this:

<?php
function listdirs($dir) {
    static $alldirs = array();
    $dirs = glob($dir . '/*', GLOB_ONLYDIR);
    if (count($dirs) > 0) {
        foreach ($dirs as $d) $alldirs[] = $d;
    }
    foreach ($dirs as $dir) listdirs($dir);
    return $alldirs;
}

$directory_list = listdirs('xampp');
print_r($directory_list);
?>

Answer 4

Have a look at glob() or the recursive directory iterator.

Answer 5

It will use to make menu bar in directory format

$pathLen = 0;

function prePad($level)
{
  $ss = "";

  for ($ii = 0;  $ii < $level;  $ii++)
  {
      $ss = $ss . "|&nbsp;&nbsp;";
    }

    return $ss;
  }

  function myScanDir($dir, $level, $rootLen)
  {
    global $pathLen;

    if ($handle = opendir($dir)) {

      $allFiles = array();

      while (false !== ($entry = readdir($handle))) {
        if ($entry != "." && $entry != "..") {
          if (is_dir($dir . "/" . $entry))
          {
            $allFiles[] = "D: " . $dir . "/" . $entry;
          }
          else
          {
            $allFiles[] = "F: " . $dir . "/" . $entry;
          }
        }
      }
      closedir($handle);

      natsort($allFiles);

      foreach($allFiles as $value)
      {
        $displayName = substr($value, $rootLen + 4);
        $fileName    = substr($value, 3);
        $linkName    = str_replace(" ", " ", substr($value, $pathLen + 3));


        if (is_dir($fileName))
         {
               echo "<li ><a class='dropdown'><span>" . $displayName . "                    </span></a><ul>";

          myScanDir($fileName, $level + 1, strlen($fileName));
            echo "</ul></li>";
  } 
        else {
      $newstring = substr($displayName, -3);  
      if($newstring == "PDF" || $newstring == "pdf" )

          echo "<li ><a href=\"" . $linkName . "\" style=\"text-decoration:none;\">" . $displayName . "</a></li>";

        }
  $t;
        if($level != 0)
        {
          if($level < $t)
          {
        $r = int($t) - int($level);
        for($i=0;$i<$r;$i++)
        {
            echo "</ul></li>";
        }
          } 
        }
              $t = $level;
      }
          }

        }
        ?>

                                        <li style="color: #ffffff">

                                                <?php                                                   
   //  ListFolder('D:\PDF');
     $root = 'D:\PDF';
   $pathLen = strlen($root);

    myScanDir($root, 0, strlen($root)); 
     ?>


                                        </li>

Answer 6

Here is A simple function with scandir& array_filter that do the job. filter needed files using regex. I removed . .. and hidden files like .htaccess, you can also customise output using <ul> and colors and also customise errors in case no scan or empty dirs!.

function getAllContentOfLocation($loc)
{   
    $scandir = scandir($loc);

    $scandir = array_filter($scandir, function($element){

        return !preg_match('/^\./', $element);

    });

    if(empty($scandir)) echo '<li style="color:red">Empty Dir</li>';

    foreach($scandir as $file){

        $baseLink = $loc . DIRECTORY_SEPARATOR . $file;

        echo '<ol>';
        if(is_dir($baseLink))
        {
            echo '<li style="font-weight:bold;color:blue">'.$file.'</li>';
            getAllContentOfLocation($baseLink);

        }else{
            echo '<li>'.$file.'</li>';
        }
        echo '</ol>';
    }
}
//Call function and set location that you want to scan 
getAllContentOfLocation('../app');
