How to get file name and its full path with PHP using scandir

Question

I want to print file name and its full path of files in a folder and sub-folders also. My Code:

function listFolderFiles($dir){
    $ffs = scandir($dir);
    echo '<ol>';
    foreach($ffs as $ff){
        if($ff != '.' && $ff != '..'){
            echo '<li>'.$ff;
            if(is_dir($dir.'/'.$ff)) listFolderFiles($dir.'/'.$ff);
            echo '</li>';
        }
    }
    echo '</ol>';
}

listFolderFiles('Main Dir');

But it is only printing the file name not the path.

Answer 1

Try this:

function listFolderFiles($dir){
    $ffs = scandir($dir);
    echo '<ol>';
    foreach($ffs as $ff){
        if($ff != '.' && $ff != '..'){
            echo '<li>'.$ff;
            echo "   Real Path: ". $dir.'/'.$ff;
            if(is_dir($dir.'/'.$ff)) 
                    listFolderFiles($dir.'/'.$ff);
            echo '</li>';
        }
    }
    echo '</ol>';
}

listFolderFiles('/var/www/TestFiles');

Answer 2

check out this:

  echo '<li>'.$ff ." and full path is ". realpath($ff) . PHP_EOL;
