List folder and subfolders in a PHP foreach

Question

I’m using the library Comic to extract information from a file .torrent, the idea and lists the information of the torrent files in a table using the foreach, however during listing, files that are inside a directory do not appear as they should, only the path to the file appears.

• The library Comic centralizes file and folder information into one array multidimensional.

• I removed the classes to shorten the code.

• I’ll leave the project’s source on github for those who want to take a closer look.

As appears:

How could you leave it so, making the files follow the directory and the subdirectories:

Display the first folder and list the files inside, so on.

<table>
    <thead>
        <tr>
            <th scope='col'>ARQUIVOS</th>
            <th scope='col'>TAMANHO</th>
        </tr>
    </thead>
<tbody>
<?php if(isset($torrent->result['info']['files'])) {
    foreach($torrent->result['info']['files'] as $file) {
    echo "<tr><td>
    <a>".extension(implode('\\',$file['path']))."</a>".implode('\\',$file['path'])."</td>
    <td>".$file['length'])."</td></tr>";
    } ?>
    <?php } else { 
    echo "<tr><td>".$torrent->result['info']['name']."</td>
    <td>".$torrent->result['info']['length']."</td></tr>";
    } ?>
</tbody>
</table>

I created these scripts to run result of BDECODE and create an array, maybe one of these options will help you. = D

This option creates an array where the key is the file path.

require_once 'BDecode.php';
$tor = new BDECODE('file.torrent');

$dir = [];
foreach( $tor->result['info']['files'] as $file ){
    $filename = array_pop($file['path'] );

    /// key inicial 
    $key = "/"; 

    /// gera a $key baseado no path
    if( count($file['path']) ) 
        $key .= implode("/",$file['path']);

    /// cria $key na array caso não exista
    if( !isset($dir[$key]) ) $dir[$key] = [];

    /// adiciona um novo arquivo na $key
    array_push($dir[$key],$filename);
    /// array_push($dir[$key], [ $filename, $file['length'] ] );
}

Exit:

This option creates an array of arrays.

require_once 'BDecode.php';
$tor = new BDECODE('file.torrent');

function recursiveDir($path,&$dirbase ){

    if( count($path) > 1 )
    {
        /// criar diretorio com o nome
        $dirname = array_shift($path);
        if( !isset($dirbase[ $dirname ]) ) $dirbase[ $dirname ] = []; /// criar o diretorio caso nao exista
        recursiveDir( $path, $dirbase[ $dirname ] );  /// chama novamente para criar subdirs, e adicionar arquivos
    }
    else
    {
        /// pode se criar uma key ( Ex.: '.' ou 'files' ) ou apenas array_push no arquivo
        /// array_push( $dirbase, array_shift($path) );
        if( !isset($dirbase['.']) ) $dirbase['.'] = [];
        array_push( $dirbase['.'], array_shift($path) ); // guarda o arquivo na array de key '.'
    }
}

$dir = [];
foreach( $tor->result['info']['files'] as $file ){
    recursiveDir( $file['path'] , $dir );
}

print_r($dir);

Note that the key '.' is the list of files in the folder, all other Keys are subdirectories.

A variation of the second option, if you want the $file['length'] along with the file you can change some lines and instead of '.' be a list of files it turn into a list of [ arquivo, length ]

Thus remaining:

require_once 'BDecode.php';
$tor = new BDECODE('file.torrent');

function recursiveDir($path,&$dirbase,$length ){
///                                      ^
///                                    mudei aki    
    if( count($path) > 1 )
    {
        /// criar diretorio com o nome
        $dirname = array_shift($path);
        if( !isset($dirbase[ $dirname ]) ) $dirbase[ $dirname ] = []; /// criar o diretorio caso nao exista
        recursiveDir( $path, $dirbase[ $dirname ], $length );  /// chama novamente para criar subdirs, e adicionar arquivos
        //                                             ^
        //                                            mudei aqui
    }
    else
    {
        /// pode se criar uma key ( Ex.: '.' ou 'files' ) ou apenas array_push no arquivo
        /// array_push( $dirbase, array_shift($path) );
        if( !isset($dirbase['.']) ) $dirbase['.'] = [];
        array_push( $dirbase['.'], [array_shift($path), $length] ); // guarda o arquivo na array de key '.'
        //                                        ^
        //                                      mudei aki, virou array de arquivo, length
    }
}

$dir = [];
foreach( $tor->result['info']['files'] as $file ){
    recursiveDir( $file['path'] , $dir , $file['length'] );
    //                                        ^
    //                                      mudei aki
}

The output of this would be +/- like this:
