The common ways to list files and folders in PHP are:

1. Use scandir() to get an array of files and folders – $contents = scandir("FOLDER");
2. Use glob() to selectively get files and folders.
   • $pictures = glob("FOLDER/*.{jpg,jpeg,png,gif}", GLOB_BRACE);
   • $folders = glob("FOLDER/*", GLOB_ONLYDIR);
3. Lastly, use opendir() to loop through a folder.
   • $fh = opendir("FOLDER");
   • while (($entry = readdir($fh)) !== false) { echo $entry; }
   • fclose($fh);

That should cover the basics, but read on for more examples!

All right, let us now get into the various examples of how to list files and folders in PHP.

METHOD 1) SCANDIR

1-scandir.php

<?php
// (A) GET ALL FILES + FOLDERS
$contents = scandir(__DIR__);

// PASS IN A SECOND PARAMETER TO SORT
//$contents = scandir($target, SCANDIR_SORT_DESCENDING);
//$contents = scandir($target, SCANDIR_SORT_NONE);

// (B) LOOP THROUGH ALL FILES + FOLDERS
foreach ($contents as $c) {
  if ($c!="." && $c!="..") {
    echo is_dir($c) ? "DIR" : "FILE" ;
    echo " - $c<br>";
  }
}

This is as easy as it gets, just use scandir("FOLDER") to get an array of all the files and folders. But take note, we can’t really “customize” this function to get “certain file types only”, and it is potentially bad for folders with a lot of files.

METHOD 2) GLOB

2-glob.php

<?php
// (A) GET ALL PHP + TEXT FILES
$scripts = glob(__DIR__ . DIRECTORY_SEPARATOR . "*.{php,txt}", GLOB_BRACE);
print_r($scripts);

// (B) GET FOLDERS ONLY
$folders = glob(__DIR__ . DIRECTORY_SEPARATOR . "*" , GLOB_ONLYDIR);
print_r($folders);

To get a “customized files list”, use the glob() function instead – We can pretty much restrict to any file type, get folders only, and even do very specific searches.

METHOD 3) OPENDIR

3-opendir.php

<?php
// (A) OPEN FOLDER + READ ENTRIES
$target = __DIR__;
if ($fh = opendir($target)) {
  while (($entry = readdir($fh)) !== false) {
    // (B) IGNORE "." AND ".."
    if ($entry!="." && $entry!="..") {
      // (C) FILE OR FOLDER?
      $thisE = $target . DIRECTORY_SEPARATOR . $entry;
      echo is_dir($thisE) ? "Directory" : "File";
      echo " - $thisE<br>";
    }
  }
  closedir($fh);
}

Have a massive folder with thousands of files? This is how we should deal with it – Read the entries one-by-one.

EXTRA) RECURSIVE GET SUB-FOLDERS

4-recursive.php

<?php
// (A) RECURSIVE GET FILES + FOLDERS
function getFF ($path) {
  // (A1) GET FILES
  $files = glob("$path*");
 
  // (A2) GET FOLDERS
  $folders = glob("$path*", GLOB_ONLYDIR);
 
  // (A3) OUTPUT CURRENT PATH
  echo "<h2>$path</h2><br>";
  print_r($files);
  print_r($folders);

  // (A4) RECURSIVE LOOP
  if (count($folders)!=0) {
    foreach ($folders as $f) {
      getFF($f . DIRECTORY_SEPARATOR);
    }
  }
}
 
// (B) GO!
getFF(__DIR__ . DIRECTORY_SEPARATOR);

Lastly, getting the sub-folders are kind of tricky – We need a recursive function that will automatically drill into the sub-folders.
