I am wrestling with a problem. I stripped the example to this script that can be run as stand-alone application:
<?php
if(file_exists("x")){
print "<div>Deleting dir</dir>";
rmdir("x");
} else {
print "<div>Not exists</dir>";
}
clearstatcache();
mkdir("x");
If I call it repeatedly (F5 in browser) then sometimes this error occurs:
Deleting dir
Warning: mkdir(): Permission denied in F:\EclipseWorkspaces\Ramses\www\deploy\stripped_example.php on line 9
10-20 times it works OK and next time this error occurs. I googled more users has this problem but without solution.
https://github.com/getgrav/grav/issues/467
My example creates the directory in cwd, where anybody has full control. In addition the mkdir $mode parameter is ignored in windows. After the error the "x" directory truly not exists and in next attempt (F5) it is always created without error. I hopped later added "clearstatcache()" will help but nope.
In my full application I am using full file path. The deleted directory is not empty and I must clean it first. After successfull deleting the error occurs almost always.
My system is Windows 7, PHP 7.0.5, Apache 2.4
Windows doesn't let you delete things if another process is accessing them.
Check if your antivirus or some other process is opening the folder.
You can check this in resource monitor, from task manager.
Try the code with additional check on existing:
<?php
if(is_dir("x")){
print "<div>Deleting dir</dir>";
rmdir("x");
} else {
print "<div>Not exists</dir>";
}
clearstatcache();
if (!is_dir("x")) {
mkdir("x");
}
Had the same problem with Windows 10, Xampp and PHP 7. Problem was Kaspersky Internet Security, scanning and blocking the directory. Disabling KIS mkdir always works for me. Instead of directly recreating you can try rename, if disabling security software is not an option for you.
$time = time();
mkdir($path . $time);
rename($path . $time, $path);

I am trying to create symlink in php with following code:
$link = (session_save_path() ? session_save_path() : sys_get_temp_dir()) . "/sess_" . $this->generateSessionId($_REQUEST['broker'], $_REQUEST['token']);
if (!file_exists($link)) $attached = symlink('sess_' . session_id(), $link);
if (!$attached) trigger_error("Failed to attach; Symlink wasn't created.".$link, E_USER_ERROR);
I am using domain name instead of localhost. I tried to run this code on
Windows 7 with Apache, and Windows 8 with IIS / IIS Express / Apache
Everytime I get same error in logs as follows:
symlink(): Could not fetch file information(error 2)
It would be great if someone can help me out in this, I already spent whole night on this thing.
Finally I found the problem.
I don't know how this code has worked for me before.
But now I checked the full path of file. It was simply session save path was different than temporary files path. So I used same session path in both links and it worked for me.
Still Thank you guys to provide me help about it.
although file_put_contents and file_get_contents works for /var/www/html/ they not work for any other directories that have same owner(apache) and chmod(644). What may be the reason? Thanks for helps...
edit:
working code:
$contents = file_get_contents("/var/www/html/osman");
$contents = str_replace("mehmet", '', $contents);
file_put_contents("/var/www/html/osman", $contents);
not working code:
$contents = file_get_contents("/opt/blaris/etc/webfilter/lists/osman");
$contents = str_replace("mehmet", '', $contents);
file_put_contents("/opt/blaris/etc/webfilter/lists/osman", $contents);
and as I sad before two file have same owner and chmod...
Ibrahim
as you mentioned both function (get and put) return false. I am pretty sure this is caused by improper set file/directory permissions (had a same issue some time ago ...).
I solved it by checking the path (in your case "/opt/blaris/etc/webfilter/lists/") if all permissions are set as they should. This also includes read/write permissions for the lists directory itself and ALL directories above.
So make sure all directories in your path are (at least) executable by the apache user (e.g.
Is /opt executable for apache user?
Is /opt/blaris executable ...
Is /opt/blaris/etc executable ...
)
Also make sure the PHP script runs really under the apache user (<?php echo shell_exec('whoami'); ?> should give you the information)
If you want to debug it on shell level you may try the following command and see what the output says (in case you have the rights to perform the command on the server ...):
sudo -u apache touch /opt/blaris/etc/webfilter/lists/osman
Hope that helps ;)
I can't figure out why this won't work.
$docRoot = getenv("DOCUMENT_ROOT");
include_once($docRoot."/conn/connection.php");
include_once($docRoot."/auth/user.php");
It works locally through wamp, but it won't work on my live server. I tried this:
if(!include_once($docRoot."/auth/user.php")){
session_start();
$debug = array();
$debug["docRoot"] = $docRoot;
$debug["inc_path"] = $docRoot."/auth/user.php";
$debug["file_exists"] = file_exists($debug["inc_path"]);
$_SESSION['DEBUG'] = $debug;
// exit
header("Location:debug.php");
exit();
}
The debug page just echoes that array and it shows the correct absolute paths and indicates that the file does in fact exist. So why didn't the include_once() work? The server (a DV account on a MediaTemple server) has not been configured at all, so I wonder if there is an apache or php setting that is messing with me.
Ultimately, what I want here is a way to refer to a file in such a way that if I move the file, or include it in another file, nothing will break. Any ideas?
In your debugging you might try is_readable($docRoot."/conn/connection.php"). The file_exists function will return true even if the file does not have readable permissions.
If you get an error code we might be able to provide more info as to what is going wrong.
Turn on error reporting dummy. It turns out one of the includes on another file was breaking this page and I wasn't able to trace that out until I turned on error reporting.
Incidentally, the problematic include was missing a leading slash in the filepath ( include("dir/file.ext"); ) which works on my local wamp setup and breaks on the linux server.
I am writing a simple SFTP client in PHP because we have the need to programatically retrieve files via n remote servers. I am using the PECL SSH2 extension.
I have run up against a road block, though. The documentation on php.net suggests that you can do this:
$stream = fopen("ssh2.sftp://$sftp/path/to/file", 'r');
However, I have an ls method that attempts to something similar
public function ls($dir)
{
$rd = "ssh2.sftp://{$this->sftp}/$dir";
$handle = opendir($rd);
if (!is_resource($handle)) {
throw new SFTPException("Could not open directory.");
}
while (false !== ($file = readdir($handle))) {
if (substr($file, 0, 1) != '.'){
print $file . "\n";
}
}
closedir($handle);
}
I get the following error:
PHP Warning: opendir(): Unable to open ssh2.sftp://Resource id #5/outgoing on remote host
This makes perfect sense because that's what happens when you cast a resource to string. Is the documentation wrong? I tried replacing the resource with host, username, and host and that didn't work either. I know the path is correct because I can run SFTP from the command line and it works fine.
Has anyone else tried to use the SSH2 extenstion with SFTP? Am I missing something obvious here?
UPDATE:
I setup sftp on another machine in-house and it works just fine. So, there must be something about the server I am trying to connect to that isn't working.
When connecting to a SFTP server and you need to connect to the root folder (for instance for reading the content of the folder) you would still get the error when using just "/" as the path.
The solution that I found was to use the path "/./", that's a valid path that references to the root folder. This is useful when the user you are logging with has access only to its own root folder and no full path is available.
So the request to the server when trying to read the contents of the root folder should be something like this:
$rd = "ssh2.sftp://{$this->sftp}/./";
For php versions > 5.6.27 use intval()
$sftpConnection = ssh2_connect($host);
$sftp = ssh2_sftp($sftpConnection);
$fp = fopen("ssh2.sftp://" . intval($sftp) . $remoteFile, "r");
https://bugs.php.net/bug.php?id=73597
I'm having a similar issue. I assume you are doing something similar to this:
$dir = "ssh2.sftp://{$sftp}{$remote_dir}";
$handle = opendir($dir);
When $remote_dir is the full path from root then open_dir works. If $remote_dir is just '/' or '', then I get the 'unable to open' error as you did.
In my case, it seems ssh connects at the root folder instead of the 'home' directory as ftp does. You mentioned that it worked on a different server, so I wonder if it is just a config issue.
the most easiest way to get SFTP working within PHP (even on windows) without installing any extension etc is PHPSECLIB: http://phpseclib.sourceforge.net/ . The SSH stuff is completely implemented in a PHP class.
You use is like this:
<?php
include('Net/SFTP.php');
$sftp = new Net_SFTP('www.domain.tld');
if (!$sftp->login('username', 'password')) {
exit('Login Failed');
}
echo $sftp->pwd();
?>
The documentation on that page contains an error. Take a look at the example here instead: http://php.net/ssh2_sftp - what you actually need to do is to open a special SFTP resource using ssh2_sftp() prior to using it with fopen(). And yes, it looks just like that, e.g. "Resource #24" when converted to string... a bit weird but apparently it works.
Another caveat is that SFTP starts in the root directory rather than the home directory of the remote user, so your remote path in the URI should always be an absolute one.
I just had the same issue, but I could figure out the problem.
On my case, when connecting to the server, I was going to the root of the account, and due to server configs I wasn't able to write there.
I have connected to the account using a fireFTP, and so I could see where the root of the account was...it was the root of the server.
I had to include the whole path until the folder where I am allowed to write, and so I could solve the issue.
So, my advice is to get the path using a graphic interface (I have used fireFTP), and add the whole path to your code.
$pathFromAccountRootFolderToMyDestinationFolder = '/Account/Root/Folder/To/My/Folder';
$stream = fopen("ssh2.sftp://".$sftp."/".$pathFromAccountRootFolderToMyDestinationFolder."/myFile.ext", 'r');
Hope this will help you and other people with the same issue!
Cheers!
I recently tried to get SFTP on PHP working and found that phpseclib was a lot easier to use:
http://phpseclib.sourceforge.net/
If you have the luxury of not being on a shared host and can install whatever extensions you want to maybe the PECL extension would be better but not all of us are so lucky. Plus, phpseclib's API looks a bit more intuitive, being OOP and all.
My issue was, that I was connecting in function and returning string URL with resource inside. Unfortunatelly resource is than created in function context and garbage collector is disconnecting resource on function end. Solution: return resource by reference and unset it manually in more complex context.
Solved my issue by enabling sftp support on the (Powershell) server
This is a bug in the ssh2 package that I found years ago and posted a patch to php.net. It fixes this issue but requires a rebuild of the ssh2 pecl package. You can read more here: https://bugs.php.net/bug.php?id=69981. I included a patch there to the ssh2_fopen_wrappers.c file in the package to fix the issue. Here is a comment I included:
Here is a line of code from ssh2_fopen_wrappers.c that causes this bug: (comment included)
/*
Find resource->path in the path string, then copy the entire string from the original path.
This includes ?query#fragment in the path string
*/
resource->path = estrdup(strstr(path, resource->path));
This line of code -- and therefore this bug -- was introduced as a fix for bug #59794. That line of code is attempting to get a string containing the part, query and fragment from the path variable.
Consider this value for the path variable:
ssh2.sftp://Resource id #5/topdir?a=something#heading1
When resource->path is "/topdir", the result is that "/topdir?a=something#heading1" gets assigned to resource->path just like the comment says.
Now consider the case when resource->path is "/". After the line of code is executed, resource->path becomes "//Resource id#5/topdir#heading1". This is clearly not what you want. Here's a line of code that does:
resource->path = estrdup( strstr( strstr( path, "//" ) + 2, "/" ) );
You may also need to apply the patch for bug # 73597 which removes "Resource id #" from the path string before calling php_url_parse().
