List all folders subfolders and files in a directory using php

Question

Please give me a solution to list all 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 a list of all files within each folder.

Is there a shell script command in php?

Answer 1

A very simple way to display the folder structure is to use the RecursiveTreeIterator class (PHP 5 >= 5.3.0, PHP 7) and generate an ASCII graphical tree.

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

You can also have some control over the ASCII representation of the tree by changing the prefix using RecursiveTreeIterator::setPrefixPart, such as $it->setPrefixPart(RecursiveTreeIterator::PREFIX_LEFT, "| ");

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');
