I'm making a script to open remote file (ftp) and edit it with fopen and fwrite.I have problem while connecting to ftp.I made this code
$handle = fopen("ftp://".$ftp['username'].":".$ftp['password']."#".$ftp['server']."/cstrike/addons/amxmodx/configs/users.ini", "w") or die("ftp error");
fwrite($handle,$text."\n") or die('err2.');
al variables are set.I tried with ftp://... in web page and it works.allow_url_fopen is On...
It just says "ftp error"
The ftp:// handler only allows creating new files with fopen("ftp://...", "w");.
If the file already exists you can only write to it if you open it with overwriting set, i.e mode w+.

I'm trying to create FTP Process that output its progress.
I found this answer rather simple on Getting ftp_put progress
by Martin Prikryl
<?php
$local_path = "\Local\Path\Local_File.zip";
$remote_path = 'ftp://username:password#address/Remote_File.zip';
$size = filesize($local_path);
$hin = fopen($local_path, "rb") or die("Cannot open source file");
$hout = fopen($remote_path, "wb") or die("Cannot open destination file");
while (!feof($hin))
{
$buf = fread($hin, 10240);
fwrite($hout, $buf);
echo "\r".intval(ftell($hin)/$size*100)."%";
}
fclose($hin);
fclose($hout);
This code is working.
What I want to ask is, if I were to use FTP URL Protocol Wrapper (ftp://) as the URL. Does it copy file using the FTP? Or is it just copying with a normal PHP Command?
Because I was asked to create an FTP process for my project, but I need the progress when it is copying.
Thanks before :)
FTP URL wrapper uses FTP protocol under the hood. That's why they are called "FTP".
I have no idea, what you mean by "copying with a normal PHP Command". If your only interface to the server is FTP, and the wrapper were using anything else than FTP, then the wrapper would obviously fail. If it works, it only proves that it uses FTP.
Documentation for FTP URL protocol wrapper says:
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.
The PHP file_put_contents function works perfectly fine when the file exists. If the file does not exist I receive the error "failed to open stream: No such file or directory".
$file = '../templates/stuff.xml';
if (!file_exists($file)) {$file = '../'.$file;}
$var['xhtml'] = $_POST['post_xhtml'];
$file_contents = serialize($var);
file_put_contents($file,$file_contents);
I tried the same thing with fopen and fwrite using the correct flags (w, w+ and tried the others) yet still had the same problem: if the file already existed it worked just fine, otherwise it would give me the same error message.
I know the file path is correct. I'm using Windows 7 for local development.
When the file doesn't exist, you are prepending ../ to the path, thus you are trying to write to:
../../templates/stuff.xml
Are you sure that the folder ../../templates exists (and that PHP can write to it)?
Before you write to a file, you need to check that the folder exists. Try using is_dir():
if(is_dir(dirname($file))){
file_put_contents($file, $file_contents);
}
I have a vb.net app that webrequests a PHP file which does this:
<?php
$msg = $_GET['w'];
$logfile= 'savedrv.idps';
$fp = fopen($logfile, "w");
fwrite($fp, $msg);
fclose($fp);
?>
I want to make a PHP file that will open the new file created "savedrv.idps" so I can read it in vb.net. This is what I tried:
<?php
$logfile= 'reg.idps';
$fp = fopen($logfile, "r");
fclose($fp);
?>
How can I accomplish this?
Most likely your IIS settings for this Virtual Directory forbid a file with this extension to be browsed to. I got 404.7 error attempting to open a file in IE when I browsed to the URL: http://localhost/mysite/myvbfile.vb Using your browser, try to open the same URL that your VB program is attempting to access. I anticipate that you will get the 404.7 error in the browser window too.
You have two approaches here:
Have your PHP script write the file to a location outside of IIS where your VB.Net program can access.
Modify the Request Filtering in IIS for your site so that this file can be browsed.

I'm trying to write a sizable chunk of data to a file that is opened via fopen() in php. The protocol wrapper I'm using is ftp, so the file is remote to the server running the php code. The file I'm writing to is on a Windows server.
I verified that the file does, in fact, get created by my php code, but the problem is that the data within the file is either non-existant (0KB) or writing to the file stops prematurely. Not sure why this is the case.
Here is the code I am using for handling the operation:
$file_handle = fopen($node['ftp'].$path_to_lut, "wb", 0, $node['ftp_context']);
include_once($file);
if ($file_handle)
{
fwrite($file_handle, $string); //$string is inside included $file
fclose($file_handle);
} else {
die('There was a problem opening the file.');
}
This code works fine when I host it on my local machine, but when I upload it to my webhost (Rackspace Cloud), it fails. This leads me to believe it's an issue related to the configuration of the my server at Rackspace, but want to know if there is anything I can do to my php code to make it more robust.
Any ideas to ensure fwrite actually finishes writing the string to the remote machine?
Thanks!
Okay, I changed the code that writes to the file like so:
if ($file_handle)
{
if ($bytesWritten = fwrite($file_handle, $string) ) {
echo "There were " . $bytesWritten . " bytes written to the text file.";
}
if (!fflush($file_handle)) {
die("There was a problem outputting all the data to the text file.");
}
if (!fclose($file_handle)) {
die("There was a problem closing the text file.");
}
} else {
die("No file to write data to. Sorry.");
}
What is strange is that the echo statement shows the following:
There were 10330 bytes written to the text file.
And yet, when I verify the text file size via FTP it shows it to be 0K and the data inside the file is, in fact, truncated. I can't imagine it has to do with the FTP server itself because it works if the PHP is hosted on a machine other than the one on Rackspace Cloud.
** UPDATE **
I spoke to a Rackspace Cloud rep who mentioned that they require passive ftp if you're going to ftp from their servers. I setup the remote server to handle passive ftp connections, and have verified that passive ftp now works on the remote server via the OSX Transmit ftp client. I added:
ftp_pasv($file_handle, true);
Right after the fopen() statement, but I get an error from PHP saying the I didn't provide a valid resource to ftp_pasv(). How can I ensure that the connection to the ftp site that PHP makes is PASV and not ACTIVE and still use fwrite()? Incidentally, I've noticed that the Windows machine reports that the file being written by my PHP code is 4096 bytes on disk. It never gets beyond that amount. This led me to change the output_buffering php value to 65536 just to troubleshoot, but that didn't fix the issue either. . .
** UPDATE PART DUEX **
Troubleshooting the problem on the my virtual server on the Rackspace Cloud Sites product was proving too difficult because they don't offer enough admin rights. I created a very small cloud server on Rackspace's Cloud Server product and configured everything to the point where I'm still seeing the same error with fwrite(). To make sure that I could write a file from that server to a remote server, I used basic ftp commands within my bash shell on the cloud server. It worked fine. So, I assume that there is a bug within the php implementation of fwrite(), and that it is probably due to some type of data throttling issue. When I write to the remote server from my local environment which has a slow upspeed compared to what is offered on the Rackspace Cloud server, it works fine. Is there any way to effectively throttle down the speed of the write? Just askin' :)
** UPDATE PART III *
So, I took the suggestion from #a sad dude and implemented a function that might help somebody trying to write to a new file and send it off in its entirety via ftp:
function writeFileAndFTP($filename=null, $data=null, $node=null, $local_path=null, $remote_path=null)
{
// !Determin the path and the file to upload from the webserver
$file = $local_path.'/'.$filename;
// !Open a new file to write to on the local machine
if (!($file_handle = fopen($file, "wb", 0))) {
die("There was a problem opening ".$file." for writing!");
}
// !Write the file to local disk
if ($bytesWritten = fwrite($file_handle, $data) ) {
//echo "There were " . $bytesWritten . " bytes written to " . $file;
}
// !Close the file from writing
if (!fclose($file_handle)) {
die("There was a problem closing " . $file);
}
// !Create connection to remote FTP server
$ftp_cxn = ftp_connect($node['addr'], $node['ftp_port']) or die("Couldn't connect to the ftp server.");
// !Login to the remote server
ftp_login($ftp_cxn, $node['user'], getPwd($node['ID'])) or die("Couldn't login to the ftp server.");
// !Set PASV or ACTIVE FTP
ftp_pasv($ftp_cxn, true);
// !Upload the file
if (!ftp_put($ftp_cxn, $remote_path.'/'.$filename, $file, FTP_ASCII)) {
die("There was an issue ftp'ing the file to ".$node['addr'].$remote_path);
}
// !Close the ftp connection
ftp_close($ftp_cxn);
}
The length of the string fwrite can write in one go is limited on some platforms (which is why it returns the number of bytes written). You can try running it in a loop, but a better idea is to simply use file_put_contents, which guarantees that the whole string will be written.

I am trying to open an XML file in remote server through fopen() function.
I have two remote servers and the file permission of the xml is set to 777 in both servers.
i am able to open the xml from one server , but not from other. Both files can be opened in browser.
What all permission i need to set or what parameters i need to set in fopen() function.?
this is the function
function getFileData($ProjectName)
{
$file = fopen($ProjectName, "r") or exit("Unable to open File! ".$ProjectName);
$fileContent="";
while(!feof($file))
{
$fileContent.=fgets($file);
}
fclose($file);
echo $fileContent;
}
getFileData('http://serverA.com/myxml.xml'); // gives the content
getFileData('http://serverB.com/myxml.xml'); // gives the error fopen(http:/serverB.com/myxml.xml) [function.fopen]: failed to open stream: HTTP request failed!
You only have one / after http: in the last two lines - but I doubt that's the problem. Can you open the file in the browser?
Perhaps try using file_get_contents . It does the same as your function, except it's ready made and fully tested by the PHP guys.
I think there should be http://server and not http:/server.
Apart from the visible problem with URL, also check what is the value for allow_url_fopen set in your php.ini, if you can open file from one server but not from other server this may be correctly set for you, did you check about timeouts?
