PHP - Upload Files From Php Server To C++ Client Using Curl

Hi folks,

I'm curious if I can for example, save a file from my server and it will save to all other servers - obviously if they accepted the connection first. It's for a software I developed and is almost complete and know there will be frequent updates to it. Instead of users downloading upates, I want the update files from my server to somehow synchronize to their server automatically?

Anything called this??

Thanks for info.

Hi,

I need to make web site, which will get requests from users that log in and activate those scripts. But, the problem is that the server has to, when the script is activated,  send request to another PC with the static IP address.  Then, that PC should execute the script, send its results to server, and then the server will notice user who activated it (clicked on the link).
So, the main problem is that server - client (static ip) communication, when the server is the first who sends request, not the client.

Any instructions would be appreciated, thanks in advance.

I have a client and a server solution setup at the moment. We are currently creating an API that will be run on the clients end that will allow their clients to connect to them. On our end, we want to log the number of attempts are API is being used so that we may charge the clients appropriately.

My question is this. How is the most efficient way of doing this? Do I call mysql_connect from the client and just shoot the insert log statements across the web. Should I create a php script on our end that looks for post/get input and takes the data and inserts it? What if the client can't connect to our server; should I cache the data and send it off all at once? Should I create a job that every hour shoots up x records API requests happened?

Relatively confused at what angle I should be taking when approaching this. I want this to be scalable to a point where we can have thousands of requests an hour, and not horribly slow down apache/mysql running at either end (Specially if the server is talking with several clients).

Hello;

I know there is a way but I just can't get it out of my head.

I have my code that i want to show to the user and then i have code i want to execute but not show anything to user. I no am not making my self clear which i am sorry for so ill give you an example.

<?
show_my_site(true);
// Now i have code which will never output anything but the webbrowser will always wait for it to complete
my_function_that_takes_time(true, 'Very Long');
?>
So what i want is some code to tell the browser thats it! You have everything. I cant use die; or exit; because i want to execute the code.

Thank-you
Paul

Can someone please help me in setting up OAuth server and client implementation in PHP? Even after lots of googling I could only find very basic and raw examples which are very difficult to understand. Thanks in advance.

So far I have managed to create an upload process which uploads a picture, updates the database on file location and then tries to upload the db a 2nd time to update the Thumbnails file location (i tried updating the thumbnails location in one go and for some reason this causes failure)

But the main problem is that it doesn't upload some files

Here is my upload.php

<?php
include 'dbconnect.php';

$statusMsg = '';

$Title = $conn -> real_escape_string($_POST['Title']) ; 
$BodyText = $conn -> real_escape_string($_POST['ThreadBody']) ; 
	 

// File upload path
$targetDir = "upload/";
$fileName = basename($_FILES["file"]["name"]);
$targetFilePath = $targetDir . $fileName;
$fileType = pathinfo($targetFilePath,PATHINFO_EXTENSION);
$Thumbnail = "upload/Thumbnails/'$fileName'";

if(isset($_POST["submit"]) && !empty($_FILES["file"]["name"])){
    // Allow certain file formats
    $allowTypes = array('jpg','png','jpeg','gif','pdf', "webm", "mp4");
    if(in_array($fileType, $allowTypes)){

        // Upload file to server
        if(move_uploaded_file($_FILES["file"]["tmp_name"], $targetFilePath)){

            // Insert image file name into database
            $insert = $conn->query("INSERT into Threads (Title, ThreadBody, filename) VALUES ('$Title', '$BodyText', '$fileName')");
            if($insert){
               $statusMsg = "The file ".$fileName. " has been uploaded successfully."; 

		$targetFilePathArg = escapeshellarg($targetFilePath);
		$output=null;
		$retval=null;
		 //exec("convert $targetFilePathArg -resize 300x200 ./upload/Thumbnails/'$fileName'", $output, $retval);
		 exec("convert $targetFilePathArg -resize 200x200 $Thumbnail", $output, $retval);
		echo "REturned with status $retval and output:\n" ; 
		if ($retval == null) { 
		echo "Retval is null\n" ;
		echo "Thumbnail equals $Thumbnail\n" ; 
		}

            }else{
                $statusMsg = "File upload failed, please try again.";
            } 
        }else{
            $statusMsg = "Sorry, there was an error uploading your file.";
        }
    }else{
        $statusMsg = 'Sorry, only JPG, JPEG, PNG, GIF, mp4, webm & PDF files are allowed to upload.';
    }
}else{
    $statusMsg = 'Please select a file to upload.';
}

//Update SQL db by setting the thumbnail column to equal $Thumbnail
$update = $conn->query("update Threads set thumbnail = '$Thumbnail' where filename = '$fileName'");
            if($update){
               $statusMsg = "Updated the thumbnail to sql correctly.";
		echo $statusMsg ;  } 
else 
{ echo "\n Failed to update Thumbnail. Thumbnail equals $Thumbnail" ; } 


// Display status message
echo $statusMsg;
?>

And this does work on most files however it is not working on a 9.9mb png file  which is named "test.png" I tested on another 3.3 mb gif file and that failed too?

For some reason it returns the following

Updated the thumbnail to sql correctly.Updated the thumbnail to sql correctly.

Whereas on the files it works on it returns

REturned with status 0 and output: Retval is null Thumbnail equals upload/Thumbnails/'rainbow-trh-stache.gif' Failed to update Thumbnail. Thumbnail equals upload/Thumbnails/'rainbow-trh-stache.gif'The file rainbow-trh-stache.gif has been uploaded successfully.

Any idea on why this is?

Hi All - I'm trying to see if the below is possible using PHP.

is it possible for php to allow a user to check if a port is open/listening on a remote server/PC, from their local machine. I've seen scripts on the web that talk about opening cmd.exe - this won't work as not all of my users will be on windows. Also saw fsock.. but the remote server is not serving http page(s). Also saw telnet, but again, some of my users may not have that windows feature enabled.

Desired workflow:

1. user enters the server hostname/IP and a port

2. my php webapp will emulate checking if that hostname and port is open from the local user's computer.

 

thanks!

What I'm trying to do is copy all  files from one server to another folder on another server. Here is what I have have so far..

<?PHP

//connection settings
$ftp_server = "server";
$ftp_user_name = "user";
$ftp_user_pass = "pass";

$dir = "/var/test/";
$destination_file = "/test/";

// set up basic connection
$conn_id = ftp_connect($ftp_server);

// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

// check connection
if ((!$conn_id) || (!$login_result))
{
echo "FTP connection has failed!";
echo "Attempted to connect to $ftp_server for user $ftp_user_name";
exit;
}
else
{
echo "Connected to $ftp_server, for user $ftp_user_name";
}


if (ftp_chdir($conn_id, $dir)) {
     echo " <br/>Current directory is now: " . ftp_pwd($conn_id) . "\n<p/>";
} else {
echo "Couldn't change directory\n<p/>";
}

$buff = ftp_rawlist($conn_id, $dir);

foreach($buff as $files)
{
echo $files. "<br/>";

if (ftp_get($conn_id, $destination_file."test.file", $dir."test.txt", FTP_BINARY)) {
     echo "<br/>Successfully written to $destination_file\n";
} else {
     echo "There was a problem\n";
}

?>

That doesn't work. Any ideas?

Thanks,
Sean

Hi,

I am trying upload files to a remote server using CURL however It is not sending all the values in the array.


$auth_local='testing123';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $auth_remote_url[$auth_no] );
curl_setopt($ch, CURLOPT_POST, TRUE);
$post_array = array(
"auth"=>$auth_local,
"auth_e"=>$auth_e,
                "my_file"=>"@".$myfile,
"md5"=>$md5,
"check"=>"0",
                "upload"=>"Upload");
curl_setopt($ch, CURLOPT_USERAGENT, "Test Upload");
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_array);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);  
$response = curl_exec($ch );
curl_close($ch );

When I check the value of $_POST['auth'] it is blank.

When I remove
"my_file"=>"@".$myfile,
It does read the correct value

Why is this not returning a value?

Thanks,

mme

OVERVIEW:

The code is about making call to the escreen web service using SOAP and Curl with client authentication required. Currently I am not getting any result only HTTP 403 and 500 errors.
The call requires client authenticate cert to be on the callng site.

QUESTIONS:

1. I need to call the RequestTicket method and pass the XML string to it.
   I don't know how to do it here(pass the method name to call).

2. For client authentication they gave us three certs, one root cert, one intermediate
   cert and a client authentication cert PROTPLUSSOL_SSOpem(it was a .pfx file). Since we are on linux we converted them to pem . In curl calls I could not find way to how to include both the root cert and the intermediate cert ,so I combined them by making a new pem file and copying the intermediate cert and them the root cert and naming it authority.pem .
I am not sure whether it works or not and would like your opinion.

3. For the current code Iam getting the error
   Error no : 77 Curl error: error setting certificate verify locations: CAfile: /home/pps/authority.pem CApath: /home/pps/

 
  If I disable the curl error message,I am getting blank page with page title 403 - Forbidden. Access is denied.

  If I comment out the CURLOPT_CAPATH and CURLOPT_CAINFO lines it gives http 500 error page with the message as content and the following at the top.

 > HTTP/1.1 500 Internal Server Error. Cache-Control: private Content-Type: text/html Server: Microsoft-IIS/7.5 X-AspNet-Version: 1.1.4322 X-Powered-By: ASP.NET Date: Thu, 02 Sep 2010 14:46:38 GMT Content-Length: 1208

If I comment out as above and also CURLOPT_SSLCERT and CURLOPT_SSLCERTPASSWD it gives 403 error with the message as content.

So I would request you to help me out by pointing out whats wrong with the current code.

Thank you.

I am trying to upload images to Imageshack directly form my site with Imageshack API, using the code bellow:

When I upload an image, the following error occurs:

"Sorry, but we've detected that unexpected data is received. Required parameter 'fileupload' is missing or your post is not multipart/form-data"

What is wrong with the code?
How can I send enctype='multipart/form-data' with cURL?

I have this code and its downloading file nicely. But I want to show a progress bar while downloading file from external server. My existing code shows progress bar but its not effective (ex. if i try to download two media file, one video and another audio, and video size is larger than audio size the audio finishes first and the progress bar shows 100% also suddenly it drops to 50% as the video is still downloading ). I mean it actually shows two progress and I need one. If I could get average percentage value of two progress that would be better. Any suggestion regarding this will be greatly appreciated.
 

<?php
set_time_limit ( 0 );
function define_progress_callback($i) {
global $conn;

curl_setopt($conn[$i], CURLOPT_PROGRESSFUNCTION, function ($resource,$download_size, $downloaded, $upload_size, $uploaded)
{
    if($download_size > 0)
        $progress = round($downloaded / $download_size  * 100);
        echo '<script language="javascript">$(".loader").loader("setProgress", '.$progress.');</script>';
        echo str_pad("",1024," ");
        flush();
        usleep(20000);

});
}

$urls = array("http://example.com/file.mp3",
                "http:/example.com/file.mp4");
$save_to='./tmp/';
$conn = array();
$fp = array();
$mh = curl_multi_init();

    foreach ($urls as $i => $url) {
    $g = $save_to . basename($url);
    $conn[$i]=curl_init($url);
    $fp[$i]=fopen ($g, "wb");
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);    // No certificate
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
        curl_setopt ($conn[$i], CURLOPT_FILE, $fp[$i]);
    curl_setopt ($conn[$i], CURLOPT_HEADER ,0);

    curl_setopt ($conn[$i], CURLOPT_MAXCONNECTS, 10);
    curl_setopt($conn[$i], CURLOPT_NOPROGRESS, false);
    define_progress_callback($i);

    do {
    $n=curl_multi_exec($mh,$active);
