hi
i have this script
can you tell me why it not list all file just list one folder and one file.

Script is here

PHP Code:


			
function dirs($dir){

  // set filenames invisible if you want

    $invisibleFileNames = array(".", "..", "items.txt", "index.php");

    // run through content of root directory

    $sfile = scandir($dir);

    foreach($sfile as $key) {

        // filter all files not accessible

        //$path = $rootDir.'/'.$content;

        if(!in_array($key, $invisibleFileNames)) {

            // if content is file & readable, add to array

            if(is_file($key) && is_readable($key)) {

                // save file name with path

                $allData['file'] = $key;



            // if content is a directory and readable, add path and name

            }elseif(is_dir($key) && is_readable($key)) {

                // recursive callback to open new directory

                $allData['dir'] = $key;



         }

        }

    }

    return $allData;





}



$my2=dirs('.');





foreach ($my2 as $value) {

   echo $value;



   }

i want to list seperate directory and seperate file
like
Directory Name:
new folder
newfolder2
FIle Name :
1.jph
2.jpg
Hope SOmeBody will help

SPL is typically the way to go for new development, but that's not where your problem is. I will present both solutions.

Here are the problem areas:

PHP Code:


			
$allData['file'] = $key;

...

$allData['dir'] = $key;

Your code is not pushing new values onto the $allData['file'] and $allData['dir'] arrays, and is instead overwriting previously stored values on each iteration.

Here's a solution using your method.. excuse me for renaming a couple of variables I believe were inappropriately named.

PHP Code:


			
function dirs($path)

{

    $nodes = array('file' => array(), 'dir' => array());

    $hidden = array('.', '..', 'items.txt', 'index.php');

    foreach (scandir($path) as $file)

    {

        if (in_array($file, $hidden))

            continue;

        if (is_file($file) && is_readable($file))

            array_push($nodes['file'], $file);

        elseif (is_dir($file) && is_readable($file))

            array_push($nodes['dir'], $file);

    }



    return $nodes;

}

Here's a solution using SPL's DirectoryIterator. There are so many similarities it's really up to you - I've found that if you don't particularly need the extra functionality of SPL objects, it is often quicker to instead use functions found in the first solution.

PHP Code:


			
function dirs($path)

{

    $nodes = array('file' => array(), 'dir' => array());

    $hidden = array('.', '..', 'items.txt', 'index.php');

    foreach (new DirectoryIterator($path) as $node)

    {

        $filename = $node->getFilename();

        if (in_array($filename, $hidden))

            continue;

        if ($node->isFile() && $node->isReadable())

            array_push($nodes['file'], $filename);

        elseif ($node->isDir() && $node->isReadable())

            array_push($nodes['dir'], $filename);

    }



    return $nodes;

}

See: SPL, DirectoryIterator

Also, your output loop must be designed to handle your 2-dimensional array. Here's an example, although concise and particularly obfuscated.

PHP Code:


			
$nodes = dirs('.');

echo 'Files:', PHP_EOL, '  ', implode(PHP_EOL . '  ', $nodes['file']), PHP_EOL, PHP_EOL;

echo 'Directories:', PHP_EOL, '  ', implode(PHP_EOL . '  ', $nodes['dir']), PHP_EOL;

Output:

Code:

Files:
  prog.php

Directories:

Good luck! Cheers.

nice and thanx for reply bro
but plz tell me how what change i have to do for sub folder file listing also in your script
you know what i really want to is
e.g
Folder
Files:
Directory:
Subfolder1
Files:
Directory:
Subfolder2
Files:
Directory:
Subfolder3
Files:
Directory:

SOmewhat recruit directory listing
but in i wan to seperate file and directory
all file and folder should list in with their files in one page.

I'm not entirely sure what you mean, but here's a quick mock up of a modified function using SPL which will recurse through subdirectories, build and return an output string with padding for recursion depth. I'm at work right now, so cut me some slack if it produces unexpected results!

PHP Code:


			
function dirs($path)

{

    settype($path, 'string');

    if (!is_dir($path) || !is_readable($path))

        return FALSE;



    $output = $path . PHP_EOL;

    $padding = 2;



    $it = new RecursiveIteratorIterator(

        new RecursiveDirectoryIterator($path),

        RecursiveIteratorIterator::SELF_FIRST);

    foreach ($it as $node)

    {

        if ($it->isDot())

            continue;

        if (!$node->isReadable())

            continue;

        if (!in_array($node->getType(), array('dir', 'file')))

            continue;



        /*

         * Define padding depending on recursion depth and

         * strip out $path and any leading directory separators

         * from the pathname, appending to $output.

         */

        $output .= sprintf('% ' . ($it->getDepth() + 1) * $padding . 's', '') .

            ltrim(substr_replace($node, '', 0, strlen($path)),

                DIRECTORY_SEPARATOR);



        if ($node->isDir())

            $output .= DIRECTORY_SEPARATOR;

        $output .= PHP_EOL;

    }



    return $output;

}



echo dirs('.');

Output

Code:

.
  directoryiterator.php
  baz/
    baz/baq/
      baz/baq/baz
      baz/baq/bar
      baz/baq/foo
  bar
  foo
  baq/

The filesystem returns files in the order they are stored on disk, so an array is probably more appropriate because we can easily sort it; I'll try and provide an update later today.

RecursiveIteratorIterator and RecursiveDirectoryIterator are the workhorses here. There's also a bit of string manipulation in order to produce that particular output, and you can also define the amount of padding per recursion depth by modifying the $padding variable. The constants PHP_EOL (new line) and DIRECTORY_SEPARATOR (/ or \) are platform-independent and defined by PHP at run-time.

If this is a web application you'll have to insert HTML line breaks by each PHP_EOL and replace leading spaces with   to see the formatting using an text/html MIME type. For example:

PHP Code:


			
echo nl2br(str_replace(' ', '&nbsp;', dirs('.')));

I hope I haven't misunderstood your question.

Cheers.

Nice work and thanks ++
bro i understand my query 100% and solve my problem
actually what i want to make form your script is like this , which i make from below script

PHP Code:


			
<?php

function dirlist($dir, $bool = "dirs"){

   $truedir = $dir;

   $dir = scandir($dir);

   if($bool == "files"){ // dynamic function based on second pram

      $direct = 'is_dir';

   }elseif($bool == "dirs"){

      $direct = 'is_file';

   }

   foreach($dir as $k => $v){

      if(($direct($truedir.$dir[$k])) || $dir[$k] == '.' || $dir[$k] == '..' || $dir[$k] == 'my.php' ){

         unset($dir[$k]);

      }

   }

   $dir = array_values($dir);

   return $dir;

}

?>

<table align=center width=100%>

//main dir file

$filem=dirlist("$dop", "files");



while(list($kf,$vf)=each($filem))

                                {$kf=$kf+1;

                               echo "<tr bgcolor=#FFCC66><td align=center><b><font color=\"#000066\"> $kf:$vf</font></b></td></tr> " ;

                                }

                                }



                                }



                                }



?>

</table>

just check and tell me that how i use your script instead of this becouse this script has one drawback is
i have to manually add while loop in it , and it make script big,
i wan to short this script as much as possible...

My main aim is , i have to scan file from all folder and move them to one folder.
