I'm trying to create a recursive function to get all directories and subdirectories from an ftp server in an array.
I tried a lot of features I found online. The one that works best for me is this:
public function getAllSubDirFiles() { $dir = array("."); $a = count($dir); $i = 0; $depth = 20; $b = 0; while (($a != $b) && ($i < $depth)) { $i; $a = count($dir); foreach ($dir as $d) { $ftp_dir = $d . "/"; $newdir = ftp_nlist($this->connectionId, $ftp_dir); foreach ($newdir as $key => $x) { if ((strpos($x, ".")) || (strpos($x, ".") === 0)) { unset($newdir[$key]); } elseif (!in_array($x, $dir)) { $dir[] = $x; } } } $b = count($dir); } return $dir; } The problem with this function is that it does not allow directories to have "."Every file located in the root directory will also be considered a directory in its name. So I tweaked the function and got this:
public function getAllSubDirFiles($ip, $id, $pw) { $dir = array("."); $a = count($dir); $i = 0; $depth = 20; $b =0; while (($a != $b) && ($i < $depth)) { $i; $a = count($dir); foreach ($dir as $d) { $ftp_dir = $d . "/"; $newdir = ftp_nlist($this->connectionId, $ftp_dir); foreach ($newdir as $key => $x) { if (!is_dir('ftp://'.$id.':'.$pw.'@'.$ip.'/'.$x)) { unset($newdir[$key]); } elseif (!in_array($x, $dir)) { $dir[] = $x; } } } $b = count($dir); } return $dir; } This works fine but gives the results I want. But it's too slow to use.
I also tried using ftp_rawlist but it had the same drawback of being very slow.
public function getAllSubDirFiles() { $dir = array("."); $a = count($dir); $i = 0; $depth = 20; $b = 0; while (($a != $b) && ($i < $depth)) { $i; $a = count($dir); foreach ($dir as $d) { $ftp_dir = $d . "/"; $newdir = $this->getFtp_rawlist('/' . $ftp_dir); foreach ($newdir as $key => $x) { $firstChar = substr($newdir[$key][0], 0, 1); $a = 8; while ($a < count($newdir[$key])) { if ($a == 8) { $fileName = $ftp_dir . '/' . $newdir[$key][$a]; } else { $fileName = $fileName . ' ' . $newdir[$key][$a]; } $a ; } if ($firstChar != 'd') { unset($newdir[$key]); } elseif (!in_array($fileName, $dir)) { $dir[] = $fileName; } } } $b = count($dir); } return $dir; } public function getFtp_rawlist($dir) { $newArr = array(); $arr = ftp_rawlist($this->connectionId, $dir); foreach ($arr as $value) { $stringArr = explode(" ", $value); $newArr[] = array_values(array_filter($stringArr)); } return $newArr; } I have been troubled by this problem for the past few days, and I am getting more and more desperate. If anyone has any suggestions please let me know

I built an OOPFTP client librarythat can help you solve this problem a lot, using just this code you can retrieve a directory listing with just additional useful information like (chmod, last modification time, size...).
Code:
// Connection $connection = new FtpConnection("localhost", "foo", "12345"); $connection->open(); // FtpConfig $config = new FtpConfig($connection); $config->setPassive(true); $client = new FtpClient($connection); $allFolders = // directory, recursive, filter $client->listDirectoryDetails('/', true, FtpClient::DIR_TYPE); // Do whatever you want with the foldersIf your server supports the
MLSDcommand and you have PHP 7.2 or higher, you can use theftp_mlsdfunction:function ftp_mlsd_recursive($ftp_stream, $directory) { $result = []; $files = ftp_mlsd($ftp_stream, $directory); if ($files === false) { die("Cannot list $directory"); } foreach ($files as $file) { $name = $file["name"]; $filepath = $directory . "/" . $name; if (($file["type"] == "cdir") || ($file["type"] == "pdir")) { // noop } else if ($file["type"] == "dir") { $result = array_merge($result, ftp_mlsd_recursive($ftp_stream, $filepath)); } else { $result[] = $filepath; } } return $result; }If you don't have PHP 7.2, you can try to implement the
MLSDcommand yourself. First, see the user notes for theftp_rawlistcommand:https://www.php.net/manual/en/ function.ftp-rawlist.php#101071
If you are unable to use
However, if you only need to work against one specific FTP server, you can useMLSD, you will particularly have problems determining whether anentry is a file or a folder. While you can use theftp_sizetrick, callingftp_sizefor each entry can take a long time.ftp_rawlist
The following code assumes common *nix format.to retrieve a list of files in a platform-specific format and parse it.function ftp_nlst_recursive($ftp_stream, $directory) { $result = []; $lines = ftp_rawlist($ftp_stream, $directory); if ($lines === false) { die("Cannot list $directory"); } foreach ($lines as $line) { $tokens = preg_split("/\s+/", $line, 9); $name = $tokens[8]; $type = $tokens[0][0]; $filepath = $directory . "/" . $name; if ($type == 'd') { $result = array_merge($result, ftp_nlst_recursive($ftp_stream, $filepath)); } else { $result[] = $filepath; } } return $result; }For DOS format, see:Get directory structure from FTP using PHP.
