I've just discovered phpseclib for myself and would like to use it for my bit of code. Somehow I can't find out how I could copy files from one sftp directory into an other sftp directory. Would be great if you could help me out with this.
e.g.:
copy all files of
/jn/xml/
to
/jn/xml/backup/
$dir = "/jn/xml/";
$files = $sftp->nlist($dir, true);
foreach($files as $file)
{
if ($file == '.' || $file == '..') continue;
$sftp->put($dir."backup".'/'.$file, $sftp->get($dir.'/'.$file));
}
This code will copy contents from "/jn/xml/" directory to "/jn/xml/backup".
To be able to move a file correctly with PHPSeclib, you can use
$sftp->rename($old, $new);
Try this:
<?php
include('Net/SFTP.php');
$sftp = new Net_SFTP('website.com');
if (!$sftp->login('user', 'pass')) {
exit('bad login');
}
$sftp->chdir('/jn/xml/');
$files = $sftp->nlist('.', true);
foreach ($files as $file) {
if ($file == '.' || $file == '..') {
continue;
}
$dir = '/jn/xml/backup/' . dirname($file);
if (!file_exists($dir)) {
mkdir($dir, 0777, true);
}
file_put_contents($dir . '/' . $file, $sftp->get($file));
}
I think this should do what was asked.
I used composer to import phpseclib so this is not exactly the code I tested, but from the other answers, the syntax should be correct.
<?php
include('Net/SFTP.php');
// connection
$sftp = new Net_SFTP('website.com');
if (!$sftp->login('user', 'pass')) {
exit('bad login');
}
// Use sftp to make an mv
$sftp->exec('mv /jn/xml/* /jn/xml/backup/');
Notes:
if any of the directories do not exist, this will fail. do echo $sftp->exec(... to get the errormsg.
you will get a warning because /jn/xml/backup/ is inside /jn/xml/, I would advise moving the files to /jn/xml.bak/
you could use 'Net/SSH2' class, since you only do a mv, and do not transfer any files. In fact, the exec is a function from the SSH2 class, and SFTP inherits it from SSH2.

I have code which generates a text file on my server. I then need this file uploaded to another server using sftp. To start things off, I do
if(performLdapOperations()) {
sleep(10);
performFtpOperation();
}
performLdapOperations produces the text file and places it on my server, performFtpOperation takes this text file and uploads to another server. This is my function
function performFtpOperation() {
global $config;
$local_directory = getcwd() .'/outputs/';
$remote_directory = '/home/newfolder/';
$sftp = new SFTP($config::FTP_SERVER, 22, 10);
if (!$sftp->login($config::FTP_USER, $config::FTP_PASSWORD)) {
exit('Login Failed');
}
$files_to_upload = array();
/* Open the local directory form where you want to upload the files */
if ($handle = opendir($local_directory))
{
/* This is the correct way to loop over the directory. */
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != "..")
{
$files_to_upload[] = $file;
}
}
closedir($handle);
}
if(!empty($files_to_upload))
{
/* Now upload all the files to the remote server */
foreach($files_to_upload as $file)
{
$success = $sftp->put($remote_directory . $file,
$local_directory . $file,
NET_SFTP_LOCAL_FILE);
}
}
}
So the text file that is produces is in my outputs folder. I then want to take this file and upload to a new server to the location /home/newfolder/
Everything seems to work, and the file seems to get uploaded to the new server. However, when I open the file that has been uploaded, all it contains is the path of where the file is, nothing else. The file on my server which is in the outputs folder contains everything, for some reason something is going wrong when sending it over sftp?
Is there anything in my code that may be causing this?
Thanks
It looks like you're using the 2.0 version of phpseclib, which is namespaced. If that's the case then the problem is with this line:
$success = $sftp->put($remote_directory . $file,
$local_directory . $file,
NET_SFTP_LOCAL_FILE);
Try this:
$success = $sftp->put($remote_directory . $file,
$local_directory . $file,
SFTP::SOURCE_LOCAL_FILE);
I have created a directory with some files in there:
index.php
one.txt
two.txt
three.txt
four.txt
In the index.php page, I am currently using this code to echo out all of the files within the directory:
<?php
$blacklist = array("index.php");
if ($handle = opendir('.')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != ".." && !in_array($entry, $blacklist)) {
echo "$entry\n";
}
}
closedir($handle);
}
?>
Now, if anyone views the index.php page, this is what they'll see:
one.txt two.txt three.txt four.txt
As you can see from the PHP code, index.php is blacklisted so it is not echoed out.
However, I would like to go a step further than this and echo out the contents of each text file rather than the filenames. With the new PHP code (that I need help with creating), whenever someone visits the index.php page, this is what they'll now see:
(Please ignore what is in the asterisks, they are not a part of the code, they just indicate what each text file contains)
Hello ** this is what the file **one.txt** contains **
ok ** this is what the file **two.txt** contains **
goodbye ** this is what the file **three.txt** contains **
text ** this is what the file **four.txt** contains **
Overall:
I would like to echo out the contents of every file in the directory (they are all text files) aside from index.php.
You could use file_get_contents to put the file into a string.
<?php
$blacklist = array("index.php");
if ($handle = opendir('.')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != ".." && !in_array($entry, $blacklist)) {
echo "$entry " . file_get_contents($entry) . "\n";
}
}
closedir($handle);
}
?>
Furthermore, you could use PHP's glob function to filter only the .txt files out, that way you do not have to blacklist files if you're going to be adding more files to that directory that need ignored.
Here is how it would be done using the glob function.
<?php
foreach (glob("*.txt") as $filename) {
echo "$filename " . file_get_contents($filename) . "\n";
}
?>
This would print the contents of the files. You can do some workaround if the path is not the current path and writing some kind of boundary between the files contents.
<?php
$blacklist = array("index.php");
if ($handle = opendir('.')) {
while (false !== ($entry = readdir($handle))) {
if ($entry != "." && $entry != ".." && !in_array($entry, $blacklist)) {
echo file_get_contents($entry) . "\n";
}
}
closedir($handle);
}
?>
I hope this helps you.
Never reinvent the wheel. Use composer.
Require symfony/finder
use Symfony\Component\Finder\Finder;
class Foo
{
public function getTextFileContents($dir)
{
$finder = (new Finder())->files()->name('*.txt');
foreach ($finder->in($dir) as $file) {
$contents = $file->getContents();
// do something while file contents...
}
}
}
I would give a chance to some SPL filesystem iterators to accomplish such this task:
$dir = '/home/mydirectory';
$rdi = new \RecursiveDirectoryIterator($dir, \FilesystemIterator::SKIP_DOTS);
$rdi = new \RegexIterator($rdi, '/\.txt$/i');
$iterator = new \RecursiveIteratorIterator($rdi, \RecursiveIteratorIterator::CHILD_FIRST);
foreach ($iterator as $file) {
echo 'Contents of the '.$file->getPathname().' is: ';
echo file_get_contents($file->getPathname());
}
This will recursively find & iterate all .txt files in given directory, including sub-directories.
Since each $file in iteration is a FilesystemIterator instance, you can use all related methods for additional controls like $file->isLink() (true for symbolic links), $file->isReadable() (false for unreadable files) etc..
If you don't want lookup sub-folders, just change the RecursiveDirectoryIterator in the second line from:
$rdi = new \RecursiveDirectoryIterator($dir, \FilesystemIterator::SKIP_DOTS);
to:
$rdi = new \DirectoryIterator($dir, \FilesystemIterator::SKIP_DOTS);
Hope it helps.
As #brock-b said, you could use glob to get the full list of files and file_get_contents to grab the contents:
$blacklist = array('index.php');
$files = glob('*.txt'); # could be *.* if needed
foreach ($files as $file) {
if (!in_array(basename($file), $blacklist)) {
echo file_get_contents($file);
}
}
Note: the blacklist wont be hit since you're seeking for *.txt files. Only useful when doing an *.* or *.php file search
i am attempting to create a web based sftp page, the only part i am having problems with is trying to determin the the listed file is a file or folder. i am sucessfully listing a directory using
$connection = ssh2_connect($_SESSION['Server'], $_SESSION['Port']);
if(ssh2_auth_password($connection, $_SESSION['Username'], $_SESSION['Password']))
{
$sftp = ssh2_sftp($connection);
$dir = "ssh2.sftp://$sftp/$directory";
$handle = opendir($dir);
while (false !== ($file = readdir($handle)))
{
if ($file != "." && $file != "..")
{
$temp=$file;
if(strlen($directory) > 0)
$Path=$directory."/".$file;
else
$Path=$file;
$statinfo = ssh2_sftp_stat($sftp, "/".$Path);
echo "$temp<br />";
}
}
closedir($handle);
}
i attempted to use the is_dir() and is_file() php function on $file which works sucessfully when working on local filesystem, but when using SFTP both come back FALSE, i attempted to use ssh2_sftp_stat() but this only gives uid, gid, size access and modified times and i dont think there is anyting that can be used to identify files of folders, if anyone has a way to resolve this i would appreaciate it greatly

I would strongly suggest using phpseclib for SSH2 purposes. It greatly simplifies tasks like this.
Solution for your problem using phpseclib should go something like this:
include('Net/SFTP.php');
$sftp = new Net_SFTP($_SESSION['Server'] . ':' . $_SESSION['Port']);
if (!$sftp->login($_SESSION['Username'], $_SESSION['Password'])) {
exit('Login Failed');
}
foreach($sftp->rawlist($dir) as $filename => $attrs) {
if ($attr['type'] == NET_SFTP_TYPE_REGULAR) {
echo $filename . ' is a regular file!';
}
if ($attr['type'] == NET_SFTP_TYPE_DIRECTORY) {
echo $filename . ' is a directory!';
}
}
These are the file type constants phpseclib uses:
file_types = array(
1 => 'NET_SFTP_TYPE_REGULAR',
2 => 'NET_SFTP_TYPE_DIRECTORY',
3 => 'NET_SFTP_TYPE_SYMLINK',
4 => 'NET_SFTP_TYPE_SPECIAL'
);
I wrote a basic content-management system for my website, including an administration panel. I understand basic file IO as well as copying via PHP, but my attempts at a backup script callable from the script have failed. I tried doing this:
//... authentication, other functions
for(scandir($homedir) as $buffer){
if(is_dir($buffer)){
//Add $buffer to an array
}
else{
//Back up the file
}
}
for($founddirectories as $dir){
for(scandir($dir) as $b){
//Backup as above, adding to $founddirectories
}
}
But it did not seem to work.
I know that I can do this using FTP, but I want a completely server-side solution that can be accessed anywhere with sufficient authorization.
Here is an alternative though: why don't you Zip the source directory instead?
function Zip($source, $destination)
{
if (extension_loaded('zip') === true)
{
if (file_exists($source) === true)
{
$zip = new ZipArchive();
if ($zip->open($destination, ZIPARCHIVE::CREATE) === true)
{
$source = realpath($source);
if (is_dir($source) === true)
{
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);
foreach ($files as $file)
{
$file = realpath($file);
if (is_dir($file) === true)
{
$zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
}
else if (is_file($file) === true)
{
$zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
}
}
}
else if (is_file($source) === true)
{
$zip->addFromString(basename($source), file_get_contents($source));
}
}
return $zip->close();
}
}
return false;
}
You can even unzip it afterwards and archive the same effect, although I must say I prefer having my backups compressed in zip file format.
if you have access to execute tar binary file through exec function it would be faster and better i think:
exec('tar -zcvf ' . realpath('some directory') .'/*);
or
chdir('some directory')
exec('tar -zcvf ./*');
You can use recursion.
for(scandir($dir) as $dir_contents){
if(is_dir($dir_contents)){
backup($dir_contents);
}else{
//back up the file
}
}
you got it almost right
$dirs = array($homedir);
$files = array();
while(count($dirs)) {
$dir = array_shift($dirs);
foreach(glob("$dir/*") as $e)
if(is_dir($e))
$dirs[] = $e;
else
$files[] = $e;
}
// here $files[] contains all files from $homedir and below
glob() is better than scandir() because of more consistent output
I us something called UPHP. Just call zip() to do that. here:
<?php
include "uphplib.php";
$folder = "data";
$dest = "backup/backup.zip";
zip($folder, $dest);
?>
UPHP is a PHP library. download: here
Here is a backup script with ftp, scp, mysqldump, pg_dump and filesystem capabilities https://github.com/skywebro/php-backup
i use a simple function to backup a file:
<?php
$oldfile = 'myfile.php';
$newfile = 'backuped.php';
copy($oldfile, $newfile) or die("Unable to backup");
echo 'Backup is Completed';
?>
when moving one file from one location to another i use
rename('path/filename', 'newpath/filename');
how do you move all files in a folder to another folder? tried this one without result:
rename('path/*', 'newpath/*');
A slightly verbose solution:
// Get array of all source files
$files = scandir("source");
// Identify directories
$source = "source/";
$destination = "destination/";
// Cycle through all source files
foreach ($files as $file) {
if (in_array($file, array(".",".."))) continue;
// If we copied this successfully, mark it for deletion
if (copy($source.$file, $destination.$file)) {
$delete[] = $source.$file;
}
}
// Delete all successfully-copied files
foreach ($delete as $file) {
unlink($file);
}
Please try this solution, it's tested successfully ::
<?php
$files = scandir("f1");
$oldfolder = "f1/";
$newfolder = "f2/";
foreach($files as $fname) {
if($fname != '.' && $fname != '..') {
rename($oldfolder.$fname, $newfolder.$fname);
}
}
?>
An alternate using rename() and with some error checking:
$srcDir = 'dir1';
$destDir = 'dir2';
if (file_exists($destDir)) {
if (is_dir($destDir)) {
if (is_writable($destDir)) {
if ($handle = opendir($srcDir)) {
while (false !== ($file = readdir($handle))) {
if (is_file($srcDir . '/' . $file)) {
rename($srcDir . '/' . $file, $destDir . '/' . $file);
}
}
closedir($handle);
} else {
echo "$srcDir could not be opened.\n";
}
} else {
echo "$destDir is not writable!\n";
}
} else {
echo "$destDir is not a directory!\n";
}
} else {
echo "$destDir does not exist\n";
}
tried this one?:
<?php
$oldfolderpath = "old/folder";
$newfolderpath = "new/folder";
rename($oldfolderpath,$newfolderpath);
?>
So I tried to use the rename() function as described and I kept getting the error back that there was no such file or directory. I placed the code within an if else statement in order to ensure that I really did have the directories created. It looked like this:
$tempDir = '/home/site/images/tmp/';
$permanentDir = '/home/site/images/' . $claimid; // this was stored above
mkdir($permanentDir,0775);
if(is_dir($permanentDir)){
echo $permanentDir . ' is a directory';
if(is_dir($tempDir)){
echo $tempDir . ' is a directory';
}else{
echo $tempDir . ' is not a directory';
}
}else{
echo $permanentDir . ' is not a directory';
}
rename($tempDir . "*", $permanentDir);
So when I ran the code again, it spit out that both paths were directories. I was stumped. I talked with a coworker and he suggested, "Why not just rename the temp directory to the new directory, since you want to move all the files anyway?"
Turns out, this is what I ended up doing. I gave up trying to use the wildcard with the rename() function and instead just use the rename() to rename the temp directory to the permanent one.
so it looks like this.
$tempDir = '/home/site/images/tmp/';
$permanentDir = '/home/site/images/' . $claimid; // this was stored above
mkdir($permanentDir,0775);
rename($tempDir, $permanentDir);
This worked beautifully for my purposes since I don't need the old tmp directory to remain there after the files have been uploaded and "moved".
Hope this helps. If anyone knows why the wildcard doesn't work in the rename() function and why I was getting the error stating above, please, let me know.
Move or copy the way I use it
function copyfiles($source_folder, $target_folder, $move=false) {
$source_folder=trim($source_folder, '/').'/';
$target_folder=trim($target_folder, '/').'/';
$files = scandir($source_folder);
foreach($files as $file) {
if($file != '.' && $file != '..') {
if ($move) {
rename($source_folder.$file, $target_folder.$file);
} else {
copy($source_folder.$file, $target_folder.$file);
}
}
}
}
function movefiles($source_folder, $target_folder) {
copyfiles($source_folder, $target_folder, $move=true);
}
try this:
rename('path/*', 'newpath/');
I do not see a point in having an asterisk in the destination
If the target directory doesn't exist, you'll need to create it first:
mkdir('newpath');
rename('path/*', 'newpath/');
As a side note; when you copy files to another folder, their last changed time becomes current timestamp. So you should touch() the new files.
... (some codes for directory looping) ...
if (copy($source.$file, $destination.$file)) {
$delete[] = $source.$file;
$filetimestamp = filemtime($source.$file);
touch($destination.$file,$filetimestamp);
}
... (some codes) ...
Not sure if this helps anyone or not, but thought I'd post anyway. Had a challenge where I has heaps of movies I'd purchased and downloaded through various online stores all stored in one folder, but all in their own subfolders and all with different naming conventions. I wanted to move all of them into the parent folder and rename them all to look pretty. all of the subfolders I'd managed to rename with a bulk renaming tool and conditional name formatting. the subfolders had other files in them i didn't want. so i wrote the following php script to, 1. rename/move all files with extension mp4 to their parent directory while giving them the same name as their containing folder, 2. delete contents of subfolders and look for directories inside them to empty and then rmdir, 3. rmdir the subfolders.
$handle = opendir("D:/Movies/");
while ($file = readdir($handle)) {
if ($file != "." && $file != ".." && is_dir($file)) {
$newhandle = opendir("D:/Movies/".$file);
while($newfile = readdir($newhandle)) {
if ($newfile != "." && $newfile != ".." && is_file("D:/Movies/".$file."/".$newfile)) {
$parts = explode(".",$newfile);
if (end($parts) == "mp4") {
if (!file_exists("D:/Movies/".$file.".mp4")) {
rename("D:/Movies/".$file."/".$newfile,"D:/Movies/".$file.".mp4");
}
else {
unlink("D:/Movies/".$file."/".$newfile);
}
}
else { unlink("D:/Movies/".$file."/".$newfile); }
}
else if ($newfile != "." && $newfile != ".." && is_dir("D:/Movies/".$file."/".$newfile)) {
$dirhandle = opendir("D:/Movies/".$file."/".$newfile);
while ($dirfile = readdir($dirhandle)){
if ($dirfile != "." && $dirfile != ".."){
unlink("D:/Movies/".$file."/".$newfile."/".$dirfile);
}
}
rmdir("D:/Movies/".$file."/".$newfile);
}
}
unlink("D:/Movies/".$file);
}
}
i move all my .json files from root folder to json folder with this
foreach (glob("*.json") as $filename) {
rename($filename,"json/".$filename);
