ftp_rawlist

(PHP 4, PHP 5, PHP 7, PHP 8)

ftp_rawlist — 返回指定目录下文件的详细列表

说明

ftp_rawlist(FTP\Connection $ftp, string $directory, bool $recursive = false): array|false

ftp_rawlist() 函数将执行 FTP LIST 命令，并把结果做为一个数组返回。

参数

ftp: FTP\Connection 实例。
directory: 要操作的目录路径，可以包括 LIST 参数。
recursive: 如果此参数为 true，实际执行的命令将会为 LIST -R。

返回值

返回一个数组，数组的每个元素为返回文本的每一行，输出结构不会被解析。使用函数 ftp_systype() 可以用来判断 FTP 服务器的类型，从而可以用来判断返回列表的类型。

不以任何方式解析输出。ftp_systype() 返回的系统类型标识符可用于确定应如何解释结果。

更新日志

版本	说明
8.1.0	现在 `ftp` 参数接受 FTP\Connection 实例，之前接受 resource。

示例

示例 #1 ftp_rawlist() 示例

<?php

// 初始化连接
$ftp = ftp_connect($ftp_server);

// 使用用户名和密码登录
$login_result = ftp_login($ftp, $ftp_user_name, $ftp_user_pass);

// 获取 / 路径下的文件列表
$buff = ftp_rawlist($ftp, '/');

// 关闭连接
ftp_close($ftp);

// 输出
var_dump($buff);
?>

以上示例的输出类似于：

 
array(3) {
  [0]=>
  string(65) "drwxr-x---   3 vincent  vincent      4096 Jul 12 12:16 public_ftp"
  [1]=>
  string(66) "drwxr-x---  15 vincent  vincent      4096 Nov  3 21:31 public_html"
  [2]=>
  string(73) "lrwxrwxrwx   1 vincent  vincent        11 Jul 12 12:16 www -> public_html"
}

Here's a simple function that'll parse the data returned by ftp_rawlist() into an associative array. I wrote it because some of the functions listed below are way to long, complex or won't work with file names that contain spaces.



<?php

    function listDetailed($resource, $directory = '.') {

        if (is_array($children = @ftp_rawlist($resource, $directory))) {

            $items = array();



            foreach ($children as $child) {

                $chunks = preg_split("/\s+/", $child);

                list($item['rights'], $item['number'], $item['user'], $item['group'], $item['size'], $item['month'], $item['day'], $item['time']) = $chunks;

                $item['type'] = $chunks[0]{0} === 'd' ? 'directory' : 'file';

                array_splice($chunks, 0, 8);

                $items[implode(" ", $chunks)] = $item;

            }



            return $items;

        }



        // Throw exception or return false < up to you

    }

?>

With this handy function based on functions presented here you get the file list in alphabetical order with all directories on top:

<?php
function rawlist_dump() {
  global $ftp_connect;
  $ftp_rawlist = ftp_rawlist($ftp_connect, ".");
  foreach ($ftp_rawlist as $v) {
    $info = array();
    $vinfo = preg_split("/[\s]+/", $v, 9);
    if ($vinfo[0] !== "total") {
      $info['chmod'] = $vinfo[0];
      $info['num'] = $vinfo[1];
      $info['owner'] = $vinfo[2];
      $info['group'] = $vinfo[3];
      $info['size'] = $vinfo[4];
      $info['month'] = $vinfo[5];
      $info['day'] = $vinfo[6];
      $info['time'] = $vinfo[7];
      $info['name'] = $vinfo[8];
      $rawlist[$info['name']] = $info;
    }
  }
  $dir = array();
  $file = array();
  foreach ($rawlist as $k => $v) {
    if ($v['chmod']{0} == "d") {
      $dir[$k] = $v;
    } elseif ($v['chmod']{0} == "-") {
      $file[$k] = $v;
    }
  }
  foreach ($dir as $dirname => $dirinfo) {
      echo "[ $dirname ] " . $dirinfo['chmod'] . " | " . $dirinfo['owner'] . " | " . $dirinfo['group'] . " | " . $dirinfo['month'] . " " . $dirinfo['day'] . " " . $dirinfo['time'] . "<br>";
  }
  foreach ($file as $filename => $fileinfo) {
      echo "$filename " . $fileinfo['chmod'] . " | " . $fileinfo['owner'] . " | " . $fileinfo['group'] . " | " . $fileinfo['size'] . " Byte | " . $fileinfo['month'] . " " . $fileinfo['day'] . " " . $fileinfo['time'] . "<br>";

All  parse_rawlist Functions here have one Problem.

when a file starts with a space character like " robots.txt ", it will be ignored.

Rename, delete will fail...

Get a listing of all files including hidden files except '.' or '..' use:



<?php

ftp_chdir($connid, $dir);

ftp_rawlist($connid, "-A");

?>

In case anybody wants to get a detailed listing using the MLSD command over a passive connection, the following function might be helpful as a starting point for your own implementation:



<?php

function ftp_mlsd($ftp, $directory) {

    $ok = @ftp_chdir($ftp, $directory);

    if (!$ok) {

        return false;

    }

    $ret = ftp_raw($ftp, 'PASV');

    if (preg_match(

        '/^227.*\(([0-9]+,[0-9]+,[0-9]+,[0-9]+),([0-9]+),([0-9]+)\)$/',

        $ret[0], $matches)) {

        $controlIP = str_replace(',', '.', $matches[1]);

        $controlPort = intval($matches[2])*256+intval($matches[3]);

        $socket = fsockopen($controlIP, $controlPort);

        ftp_raw($ftp, 'MLSD');

        $s = '';

        while (!feof($socket)) {

            $s .= fread($socket, 4096);

        }

        fclose($socket);

        $files = array();

        foreach (explode("\n", $s) as $line) {

            if (!$line) {

                continue;

            }

            $file = array();

            foreach (explode(';', $line) as $property) {

                list($key, $value) = explode('=', $property);

                if ($value) {

                    $file[$key] = $value;

                } else {

                    $filename = trim($key);

                }

            }

            $files[$filename] = $file;

        }

        return $files;

    }

    return false;

}

?>



Please note that this function ignores the setting of ftp_pasv(). Making the function to work universally for both active and passive connections is left as an exercise to the reader ;-)

Regarding converting permissions from symbolic notation to octal, note that Hazem dot Khaled at gmail dot com's chmodnum function produces INCORRECT results.  The resutls are base-10 numbers that only LOOK like they are octal numbers.  The function also ignores setuid, setgid and sticky bits, and will produce incorrect numbers if such a file is encountered.  Instead, this brute-force code works.  Maybe there is something more slick, but this isn't too CPU-intensive (note that it assumes you've error-checked that you indeed have a 10-character string!):

      $permissions = 'drwxr-xr-x';  // or whatever
      $mode = 0;

      if ($permissions[1] == 'r') $mode += 0400;
      if ($permissions[2] == 'w') $mode += 0200;
      if ($permissions[3] == 'x') $mode += 0100;
      else if ($permissions[3] == 's') $mode += 04100;
      else if ($permissions[3] == 'S') $mode += 04000;

      if ($permissions[4] == 'r') $mode += 040;
      if ($permissions[5] == 'w') $mode += 020;
      if ($permissions[6] == 'x') $mode += 010;
      else if ($permissions[6] == 's') $mode += 02010;
      else if ($permissions[6] == 'S') $mode += 02000;

      if ($permissions[7] == 'r') $mode += 04;
      if ($permissions[8] == 'w') $mode += 02;
      if ($permissions[9] == 'x') $mode += 01;
      else if ($permissions[9] == 't') $mode += 01001;
      else if ($permissions[9] == 'T') $mode += 01000;

      printf('Mode is %d decimal and %o octal', $mode, $mode);

There are a couple of php-related reasons given here for ftp_rawlist returning an empty result. However be aware that ZoneAlarm (and possibly other) firewalls can block responses without giving any visible clue so be sure to check that first.

ftp_rawlist kept returning empty file listing, it would work on some machines but not others, it turned out to be ftp_pasv command was needed.

When you try:

$path = "directory pathname with spaces";
$list = ftp_rawlist($conn_id,$path);

It doesn't work

but when you try:

$path = "directory pathname with spaces";
ftp_chdir($conn_id,$path);
$list = ftp_rawlist($conn_id,".");

It works

Why not using POSIX regex to do the job here ? A preg_replace returns the information in an associative array with the following keys:

<rights>
<number>
<owner>
<group>
<file_size>
<mod_time>
<file>
<type> * that's a bonus: it will tell you if the item is either a file or a directory

Code is shown below:

$list=@ftp_rawlist($con,$directory) ;

$items=array() ;

foreach($list as $_)
preg_replace(

'`^(.{10}+)(\s*)(\d{1})(\s*)(\d*|\w*)'.
'(\s*)(\d*|\w*)(\s*)(\d*)\s'.
'([a-zA-Z]{3}+)(\s*)([0-9]{1,2}+)'.
'(\s*)([0-9]{2}+):([0-9]{2}+)(\s*)(.*)$`Ue',

'$items[]=array(
"rights"=>"$1", 
"number"=>"$3", 
"owner"=>"$5", "group"=>"$7",
"file_size"=>"$9",
"mod_time"=>"$10 $12 $14:$15",
"file"=>"$17",

Some FTP servers only allow you to get list of files under current working directory. So if you always get result as empty array (array(0){ }), try changing the cwd befor get the list:



<?php

function ftprawlist($connid, $dir) {

  ftp_chdir($connid, $dir);

  return ftp_rawlist($connid, "-a");

}

$filedata['type'] = $filedata['access_permissions']{0};

$filedata['access_permissions'] = substr($filedata['access_permissions'],1);

// now check the date to see if the last modifcation was this year or last.

The solution of fredvanetten at tinqle dot com is nice but needs further evaluation as because of the preg_split and static listing of the variables will produce different values: comparing a file of today or an older, from a previous year:

Array
(
    [time] => 2012
    [day] => 11
    [month] => Sep
    [size] => 37262
    [group] => group
    [user] => owner
    [number] => 1
    [rights] => -rw-rw-rw-
)

The previous regular expression(by Jonathan Almarez,ergye at yahoo dot com and guru at virusas dot lt) is very good.But i found it does not  take into account for directories(number>9)

The code below not only parses:

It also parses:

3 
drwxrwxr-x   119 msik     ia           4096 Nov  5 14:19 Group3

Note that there is no standard for the format, therefore don't be suprised when parsing routines for this work perfectly on some servers, and fail horribly on some.

If you write
<?php
rawlist ($ftp, "-a");
?>
The command will be "LIST -a", so the retuned list will also contain hidden files like ".htaccess".

In this case all files and folders of the current directory are contained.
To list another folder, you must change to it with "ftp_chdir".

NO, NO, NO.

The above examples are all wrong, the spaces given in array are not there "just because", its just a tabbed structure. In php we don't have structures like in c/cpp, but the following function will do the job.

<?php

function parse_rawlist( $array ) {

    for ( $i = 1; $i < count($array); $i++ ) {

        $current = $array[$i];
    
        $structure[$i]['perms']  = substr($current, 0, 10);
        $structure[$i]['number'] = trim(substr($current, 11, 3));
        $structure[$i]['owner']  = trim(substr($current, 15, 8));
        $structure[$i]['group']  = trim(substr($current, 24, 8));
