Beware:

The array will contain complete paths, not just filenames. At least in PHP 4.3.11 when I tried 



ftp_nlist("www.example.com/docs/some/thing")



it dumped something like this:



  [0]=>

  string(41) "www.example.com/docs/some/thing/file1.htm"

  [1]=>

  string(41) "www.example.com/docs/some/thing/file2.htm"

  [2]=>

  string(41) "www.example.com/docs/some/thing/file3.htm"

  [3]=>

  string(41) "www.example.com/docs/some/thing/file4.htm"

  [4]=>

  string(41) "www.example.com/docs/some/thing/file5.htm"

better version of turigeza on yahoo com ftp_rmdirr() function.



This return true or false if the path will be removed :



function ftp_rmdirr($handle, $path)

{

    if(!@ftp_delete($handle, $path))

    {

        $list = @ftp_nlist($handle, $path);

        if(!empty($list))

            foreach($list as $value)

                ftp_rmdirr($handle, $value);

    }

    

    if(@ftp_rmdir($handle, $path))

        return true;

    else

        return false;

}

Recursive directory delete using ftp_nlist() ...

<?php 

function ftp_rmdirr($path, $handle)

    {

    if (!(@ftp_rmdir($handle, $path) || @ftp_delete($handle, $path)))

        {

        $list = ftp_nlist($handle, $path);

        if (!empty($list))

            foreach($list as $value)

                ftp_rmdirr($value, $handle);

        }

    @ftp_rmdir($handle, $path);

    }

?>

It would be very useful if it was built into php. After all most of the time we want to remove non empty directories too. I bet everyone out there dealing with the file system had faced this problem.

Here is the function that would checking whether the given path is directory or not, using ftp_nlist;



<?php

function is_ftp_dir($itempath, $ftp_server, $ftp_user_name='anonymous', $ftp_user_pass='') {

    if (empty($ftp_user_name)) {

        $ftp_user_name = "anonymous";

    }

    if ($itempath[0]!=="/") {

        $itempath = "/".$itempath;

    }



    $conn_id = ftp_connect($ftp_server);

    $login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);



    $contents = ftp_nlist($conn_id, "$itempath");



    if (!empty($contents[0])) {

        $check = str_replace($itempath, "", $contents[0]);

        if (!empty($check)) {

            return true;

        }

    }

    ftp_close($conn_id);

}



// example :

    if (is_ftp_dir("/pub/ftp/unknownitem", "ftp.nowhere", 'username', 'verysecret'')) {

        // do something related to directory handling action

    } else {

        // The target item is a file ...

    }



?>

Another file filecollect script, with static.



<?php



function filecollect($conn_id,$dir='.') {

  static $flist=array();

  if ($files = ftp_nlist($cid,$dir)){

    foreach ($files as $file) {

      if (ftp_size($cid, $file) == "-1"){

        filecollect($cid,$file);

      } else $flist[] = $file;

    }

  }

  return $flist;

}



$conn_id = ftp_connect('ftp.nowhere.com') or die("Couldn't connect to server");

  if (@ftp_login($conn_id, 'anonymous', 'pass@nowhere.com')){

    $filelist = filecollect($conn_id);

    echo "<pre>";

      print_r($filelist);

    echo "</pre>";

  }



?>

To use custom LIST - flags, for example

LIST -aF ../*/

(listing protected pub dirs)

You can use

<?php

$list = ftp_nlist($ftp, "-aF ../*/");

?>

Took me a while to clever that one out :-)

A little correction to king_killa at juggalos4life dot com's note, it isn't ftp_res, it's ftp_size.



By the way, here is a complete function that will get all the files on a server, then write them to a array.



<?php

$ftp1 = ftp_connect('ftp.nowhere1230404.foo') or die("Couldn't connect to server");

ftp_login($ftp1,'foo','bar');

ftp_pasv($ftp1, TRUE); //Passive Mode is better for this



//Get them file!

echo "Collecting Files on Neodecoder<br>";

//Set defaults just in case. PHP complains anyway if we don't.

$dir = "";



function filecollect($dir,$filelist) {

global $ftp1; //Get our ftp

$files = ftp_nlist($ftp1,$dir); //get files in directory

foreach ($files as $file) {

 $isfile = ftp_size($ftp1, $file); 

 if($isfile == "-1") { //Is a file or directory?

  $filelist = filecollect($dir.'/'.$file,$filelist,$num); //If a folder, do a filecollect on it

 }

 else {

  $filelist[(count($filelist)+1)] = $file; //If not, add it as a file to the file list

 }

}

return $filelist;

}



$filelist = filecollect($dir,$filelist);



echo "<pre>";

print_r($filelist);

echo "</pre>";

?>



This is really handy if your trying to transfer all the files from a ftp server to another server. Which, is why I made the script in the first place. heh..

ftp_nlist() or ftp_rawlist() takes ages then returns nothing...



If you are having this issue, you may need to enable PASV mode FTP transfers using the ftp_pasv() function.



Example...



<?php

$ftp_host = "yourFTPHost";

$ftp_user = "yourUsername";

$ftp_password = "yourPassword";



//Connect

echo "<br />Connecting to $ftp_host via FTP...";

$conn = ftp_connect($ftp_host);

$login = ftp_login($conn, $ftp_user, $ftp_password);



//

//Enable PASV ( Note: must be done after ftp_login() )

//

$mode = ftp_pasv($conn, TRUE);



//Login OK ?

if ((!$conn) || (!$login) || (!$mode)) {

   die("FTP connection has failed !");

}

echo "<br />Login Ok.<br />";



//

//Now run ftp_nlist()

//

$file_list = ftp_nlist($conn, "");

foreach ($file_list as $file)

{

  echo "<br>$file";

}



//close

ftp_close($conn);



?>

in windows, ftp_nlist will die on a directory with a space in it's name.  to get around this, use ftp_chdir:



//change directory

ftp_chdir($conn, "directory with spaces");

//then blindly list

$contents = ftp_nlist($conn, "");

This is an Example tp read out a Complete FTP Server ( beginn at your root dir )

    function files($dir)

    {

        /*

        if(!isset($dir) || empty($dir))

        {

            $dir=ftp_pwd($this->conn_id);

        }

        */

        unset($list);

        unset($files);

        unset($folders);

        unset($folder);

        unset($file);

        @ftp_chdir($this->conn_id, $dir);

        $dir = ftp_pwd($this->conn_id);

        $list=Array(); 

        $list=ftp_nlist($this->conn_id, "$dir"); 

        $files = Array();

        $folders = Array();

        for($i = 0; $i != sizeof($list); $i++)

        {

            $entry = str_replace("//", "", $list[$i]);

            if(@ftp_chdir($this->conn_id, $entry))

            {

                $folders[] = $entry;

                ftp_chdir($this->conn_id, $dir);

            }

            else

            {

                $files[] = $entry;

            }

        }

        print "\t<b> Dateien in ".$dir." :</b><br><br>";

        foreach($files as $file)

        {

            print $file."<br>";

        }

        print "\t<b>Ordner in ".$dir." :</b> <br><br>";

        foreach ($folders as $folder)

        {

            print "\t".$folder."<br>";

            ftp_chdir($this->conn_id, $dir);

            $this->files($folder);

        }

    }

If you do a wildcard or other search for a particular file and the file doesn't exist, Solaris FTP servers send back "search*.xml: No such file or directory" as a single element in the response array. This makes it hard to check for the presence of a file.



One possible work-around is to parse your own raw directory listing. Or you could check for the error verbatim. But different servers could return different values. A simpler way to compensate is to use the ftp_size command to validate the returned file:



if ( ($filelist = ftp_nlist( $this->conn_id, $filesearch )) === FALSE )

{

       Error( "Could not get file list" );

       return FALSE;

}

// File actually exists? Catches invalid FTP server list responses

if ( !count($filelist) || ftp_size( $this->conn_id, $filelist[0] ) == -1 )

{

       Error( "No valid files" );

       return FALSE;

}

// File is really there, fetch it or whatever else you want to do

There are some FTP servers that just dont accept the ftp_nlist command, they return a bool variable. but I think all of them accept the LIST command which is the ftp_rawlist command. So yu have to parse rawlist to nlist. I found a code here posted by "fredrik" but it shows a bug if the files at the ftp server have spaces oon theeir name... so here its a better function:

function rawlist_2_nlist($list) 

{ 

    $newlist = array();

    reset($list); 

    while (list(,$row) = each($list)) 

    {

        $buf="";

        if ($row[0]=='d'||$row[0]=='-'){ 

        $buf = substr($row,55);

        $newlist[]=$buf;

        }

    }



return $newlist; 

}

A note to developers using PHP on Windows servers: as of PHP 4.1.2, ftp_nlist() is broken in the Windows build of PHP. It will return nothing at all, even if the same code works fine on UNIX. So if you're going crazy trying to figure out why the function isn't returning anything, stop wasting your time, you're not doing anything wrong. Hopefully this will get fixed in future versions, although it's apparently been an issue since at least 4.0.6.

You can do a wildcard file listing with ftp_nlist, as in:





$list=ftp_nlist($conn_id, "$dir/*.txt");

ftp_nlist
