Listing all the folders subfolders and files in a directory using php

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

function listFolderFiles($dir){     $ffs = scandir($dir);      unset($ffs[array_search('.', $ffs, true)]);     unset($ffs[array_search('..', $ffs, true)]);      // prevent empty ordered elements     if (count($ffs) < 1)         return;      echo '<ol>';     foreach($ffs as $ff){         echo '<li>'.$ff;         if(is_dir($dir.'/'.$ff)) listFolderFiles($dir.'/'.$ff);         echo '</li>';     }     echo '</ol>'; }  listFolderFiles('Main Dir');

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>"; }

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, "|");
