PHP script that lists and edits other files

Listing everything at once is a bad idea, unless you just want to run something in these files and folders, but do not list everything.

Actually what you want is a "file manager":

• PHP File Manager on Google

  

I want to make you aware of one thing, this code can fail, regardless of who write or rewrite, if it is to be used in production I recommend looking for tools already considered, then take these codes as a case study, or test the codes very well below.

     

In GNU / Linux based servers there are folder permissions and access levels, so maybe not every file is accessible, of course I assume the files will be generated by the php script itself, so you will not have this problem with the "owner of the file "

For case studies

First create a global.php file, because we will use more than one file and in this case it is better to keep the settings in one and use include , create a file called global.php :

<?php
define('DATA_FOLDER', '/home/user/arquivos'); //Troque pela pasta que deseja editar e navegar

If you are listing a folder (which I recommend) at a time you can do so (called navegar.php ):

<?php
include 'global.php';

$ap = DATA_FOLDER;
$dir = '/';

if (empty($_GET['pasta']) === false) {
   $dir = '/' . trim($_GET['pasta'], '/');
}

if (isset($_GET['deletar']) && file_exists($ap . $dir)) {
    echo '<a href="deletar.php?arquivo=', $ap . $dir,'">Quer realmente deletar o arquivo "', $ap , $dir, '"?</a><hr>';
}

if (is_dir($ap . $dir)) {
    $dh = opendir($ap . $dir);
    if ($dh) {
        echo '<ul>';

        while (($file = readdir($dh)) !== false) {
            if ($file === '.' || $file === '..') {
               continue;
            }

            $acessivel = false;
            $atual = $ap . $dir . '/' . $file;

            if (is_dir($atual)) {
                 echo '<li> <a href="navegar.php?pasta=', $dir, '/', $file, '">', $file,'</a>';
                 $acessivel = true;
            } else if (is_file($atual)) {
                 echo '<li>', $file,' <a href="editar.php?arquivo=', $dir, '/', $file, '">[Editar]</a>';
                 $acessivel = true;
            }

            if ($acessivel) {
                echo ' <a href="deletar.php?arquivo=', $dir, '/', $file, '&amp;deletar=1">[Deletar]</a> </li>';
            }
        }

        echo '</ul>';
        closedir($dh);
    }
}
?>

<a href="navegar.php">Voltar a raiz</a>

When accessing navegar.php?pasta= it will point the new directory.

editar.php reads and writes the file, note that I used LOCK_EX to prevent more than one person from deleting while recording.

<?php
include 'global.php';

if (empty($_GET['arquivo'])) {
    echo 'Arquivo não definido';
    exit;
}

$ap = DATA_FOLDER;
$arquivo = $ap . '/' . $_GET['arquivo'];

if (false === is_file($arquivo)) {
    echo 'Arquivo não inacessivel ou invalido:', $arquivo;
    exit;
}

echo 'Você está editado: ', $arquivo, '<br>';

if (isset($_POST['conteudo'])) {
    file_put_contents($arquivo, $_POST['conteudo'], LOCK_EX);
}
?>

<form action="editar.php?arquivo=<?php echo $_GET['arquivo']; ?>" method="POST">
     <textarea name="conteudo" cols="150" rows="50"><?php
          echo htmlspecialchars(file_get_contents($arquivo));
     ?></textarea><br>
     <button type="submit">Salvar</button>
</form>

<hr>

<a href="navegar.php?pasta=<?php echo dirname($_GET['arquivo']); ?>">Voltar para navegação</a>

And finally delete.php:

<?php
if (empty($_GET['arquivo'])) {
    echo 'Arquivo não definido';
    exit;
}

include 'global.php';

$ap = DATA_FOLDER;
$arquivo = $ap . '/' . $_GET['arquivo'];

if (is_dir($arquivo)) {
    //Deleta pasta recursivamente, pois não é possivel deletar pastas que não estão vazias
    function recursive_rmdir($path) {
        if (is_dir($path) && ($dh = opendir($path))) {
            while (($file = readdir($dh)) !== false) {
                if ($file === '.' || $file === '..') {
                   continue;
                }

                $atual = $path . '/' . $file;

                if (is_dir($atual)) {
                    recursive_rmdir($atual);
                } else if (is_file($atual)) {
                    unlink($atual);
                } else {
                    echo $atual, ' é inacessivel<br>';
                }
            }
            closedir($dh);
            rmdir($path);
        } else if (is_file($path)) {
            unlink($path);
        }
    }

    recursive_rmdir($arquivo);
} else if (is_file($arquivo)) {
   if (unlink($arquivo)) {
       echo 'Arquivo "', $arquivo,'" deletado com sucesso';
   } else {
       echo 'Falha ao deletar o arquivo "', $arquivo,'"';
   }
} else {
       echo 'Arquivo "', $arquivo,'" inacessivel';
}
?>

Functions used and what you should study:

• Open directory: link
• Checks if file: link
• Veirifca if it's folder: link
• Delete files: link
• Delete empty folders: link
• Write content to a file (it's binary-safe): link
• Read the contents of a file (it's binary-safe): link

For production

If it is the case of a production environment, I recommend using well-tested applications, such as:

  

I have not tested, I do not know if they work so well, but it has repository and bug tracking

• link (GPLv2 license, full of functions, has plugins, thumbnails, ajax based)
• link (paid but seems to be well advanced and full of extra functions such as thumbnails and ajax-based)
• link
• link
• link
• link
