list files inside directory of a directory

Question

For looping all files in a directory, I created this code in php :

$dir = new DirectoryIterator(dirname(__FILE__));
$files = scandir($dir.'/');
foreach($files as $file) 
{
    echo $file;
    echo "\n";
}

However I am not able to list all files inside multiple subdirectory of a directory.

Answer 1

Use RecursiveDirectoryIterator

<?php

$path = realpath('/etc');

$objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);
foreach($objects as $name => $object){
    echo "$name\n";
}

?>
