I've an IP-associated ftp access to an host, say ftp.host.com and I need to show in php pages (hosted somewhere else) some images hosted on the ftp site
The website php pages are the only ones allowed to access ftp.host.com because of the IP policies.
Of course, if I call images with " the call is done by the client, not the server, so it fails because of IP policies.
How can I call the images from server side? I can't use CURL nor FTP_GET because of the well known ftp over NAT php bug described here:
http://www.elitehosts.com/blog/php-ftp-passive-ftp-server-behind-nat-nightmare/
And I can't patch php because it's on an hosted server so I'm out of ideas
Any idea would be greatly appreciated!
These might work for you getimagesize() and readfile()
$remoteImage = "http://www.example.com/gifs/logo.gif";
$imginfo = getimagesize($remoteImage);
header("Content-type: $imginfo['mime']");
readfile($remoteImage);

I'm running this from Filezilla remote server
anyone have any solution
<?php
echo "what a lab";
?>
For a web browser to load the output of a PHP file you need to make an HTTP request to an HTTP server which supports PHP.
FileZilla is an FTP client. It connects to FTP servers. FireZilla, if it comes into it at all, will be used only to copy the PHP file to the computer which is running both an FTP and HTTP server.
You need to enter the matching HTTP URL (e.g. http://example.com/your.php) into the address bar of your browser.
I am working on a php web app .
I need to upload a file to the web server, with customer info - customers.csv.
but this process needs to be automated ,
The file will be generated in a Point of Sale app , and the app can open a browser window with the url ...
first i taught i would do something like this www.a.com/upload/&file=customers.csv
but read on here that is not possible,
then i taught i would set a value for the file upload field and submit form automatically after x seconds. Discovered thats not possible .
Anybody with a solution , will be appreciated .
EDIT
I have tried this and it works ,file is uploaded to remote server
is it working only because the php script is running on the same pc where csv is sitting ???
$file = 'c:\downloads\customers.csv';
$remote_file = 'customers.csv';
// set up basic connection
$conn_id = ftp_connect('host.com');
// login with username and password
$login_result = ftp_login($conn_id,'user','password');
// upload a file
if (ftp_put($conn_id, $remote_file, $file, FTP_ASCII)) {
echo "successfully uploaded $file\n";
} else {
echo "There was a problem while uploading $file\n";
}
// close the connection
ftp_close($conn_id);
This is of course not possible, imagine how this could be abused to upload on linux as example the /etc/passwd. The only way it might be possible is to use a Java Applet, but this is for sure not the best way.
You could try to let your PoS Application make a web request with the customers.csv file and let a WebAPI handle the upload, this may be possible, but I have no expierence with Point of Sale Applications.
Best might be, if the solution above cannot be considered, to just prompt the user to provide the file above and check over name + content if it is the correct one.
This is a bit tricky, but if your CSV is not too long, you could encode it in base64, send to the webserver as a GET parameter and then, in the server side, decode and store it as a CSV file.
If the file is too big to do that, you have to use other method, like the java applet pointed by #D.Schalla or even install and configure a FTP server, and make the Point of Sale app uploads the file there.
Other alternative, specially good if you cannot modify the sale app, is to install a web server in the client side and write a small php script to handle the upload process. In this way, the sale app could call a local url (something like: http:// localhost/upload.php) and it's this script the one in charge to upload the file which can be achieve with a classical HTTP POST, a FTP connection or any other way you can think about.
MY Solution , which will work with out setting up web server on client side.
This is for windows but can be adapted to linux
On client side
Local Application opens cmd and runs this command ftp -n -s:C:\test.scr
WHICH opens test.scr - a file with ftp commands e.g.
open host.com
user1
passwOrd
put C:\downloads\customers.csv public_html/customers.csv

I have files that are automatically uploaded onto a server from mobile phones, and I need to automatically transfer these files from the server to another server using PHP.
Could someone please explain how I would do this?
Thanks for any help
PHP has FTP functionality built in with FTP wrappers:
Allows read access to existing files and creation of new files via FTP. If the server does not support passive mode ftp, the connection will fail.
This means you can use FTP like any other file - an extremely simple example:
<?php
$data = file_get_contents('some/other/file.txt');
$fname = "ftp://name:yourpassword#127.55.41.10:21/some/path/filename.txt";
file_put_contents($fname,$data);
?>
I am running a socket server using PHP. The socket server runs fine because I can connect to it using PHP.
Now, I have a flash application that is trying to connect to it:
this.socket.addEventListener(Event.CONNECT, onSocketConnect);
this.socket.addEventListener(Event.CLOSE, onSocketClose);
this.socket.addEventListener(IOErrorEvent.IO_ERROR, onIOError);
this.socket.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onSecError);
try {
this.socket.connect("myip", 9999);
} catch (ioError:IOError) {
this.debugLbl.text += "ioError1 "+ioError.message;
} catch (secError:SecurityError) {
this.debugLbl.text += "secError1 "+secError.message;
}
When I run the application locally, it works! However, when I upload it to my server I get a sandbox security error (#2048). The flash app is actually hosted on the same server as the socket server, and there is cross domain policy file in place.
Is it possibly you need to use a php proxy? I had to do that, doc'd it here. Although you did mention that the app's on the same server and theres a crossdomain.xml in place, so i'm probably off the mark there (btw, Flash 10 needs a different crossdomain.xml than prev versions as far as I know).
Are you actually loading the cross domain policy file? As far as I know, Flash Player only tries to load automatically the following file: http://www.example.com/crossdomain.xml. If your file is in another place, you should load it:
Security.loadPolicyFile("http://www.example.com/subfolder/crossdomain.xml");
Also, even if the app is on the same server, Flash Player believes "http://www.example.com" to be different from "http://example.com", so you should make sure you cover this possibility in the cross domain policy file:
<allow-access-from domain="*.example.com"/>
You need to pass the crossdomain.xml file by the socket, because when you work with socket dont work any policy file in the root of the app web.
Here the sample : http://www.blog.lessrain.com/as3-java-socket-connections-to-ports-below-1024/
I have a script that uses ftp_connect() among other FTP PHP functions for uploading a file.
ftp_connect() works when executed on my local development server for connecting to a remote FTP server. The same script, when executed on the remote server does not work for connecting to the exact same FTP server.
Could somebody please point me in the right direction?
Thanks!
Here is the code:
error_reporting(E_ERROR | E_WARNING | E_PARSE);
$server = 'ftp.someserver.com';
$ftpConn = ftp_connect($server);
if(!$ftpConn)
echo 'failed';
else
echo 'success';
No errors are reported.
So if I understand it correctly then the script above is installed on the server that you're trying to access using FTP (ie. the script is opening a local FTP connection)? What's the use? FTP in PHP is only useful to transfer files between 2 servers, you cannot use it to transfer files from the client to the server (since the script is executed on the server).
edit
Something I didn't add in my original comment : you could use a Java FTP applet if you want to transfer files from the client to the server. But be aware of the security issues involved (because the user credentials can be sniffed :p).
Probably firewall issues. On top of that, FTP was not designed with NAT in mind.
Try to login to the production server and use a ftp client to do the same connection.
I do not know the things inside it very well but I want to give my little help.My server is ubuntu Linux with Apache、PHP and MySQL,and my develop env is MAMP on Mac.
I met the problem suddenly and cannot find what happened because it was worked yesterday,I searched many answers and can't solved it.The ftp_connect($ftp_server) only return bool(false),but I can use my FileZilla,interesting,is it?
So I try to connect the server from my command line,like ftp 111.22.333.44,It shows:
500 OOPS: cannot read user list file:/etc/vsftpd/vsftpd.user_list
I login in my ubuntu server, and didn't find the vsftpd directory,and the vsftpd.user_listis in the directory /etc/,still don't know what happened.
So I simply create the directory and copy the file vsftpd.user_list to it.Then I try ftp 111.22.333.44(your IP address) again and it works now.
hope it help someone else.
