Hi all,

I have a question on using php to upload a file from 1 server to another server.

The condition is : when a user click a link, then the server will upload a file to another server. (remarks: not client side upload)

which php function can use in this situation? any idea or suggestion ??


thx!

One
Two

Option one can handle HTTP uploads as well as FTP, but will probably require more learning (you have to do most things through curl's setopt function, and there's a hell of a lot in there to read through).
Option two is easier, but only does FTP transfers.

A third option is just to shell out from PHP and run the command line client of your choice... probably the easiest to make work, but the hardest to troubleshoot.

it it possible to use put command to put the file to the target server ??

my point is no need the user to donwload the file.

simply simulate the upload action instead of upload from client side.

when the user click the link then trigger the shell script command to put the file from server A to server B

the target server will have a servelt to handle to upload file.

thx for reply!!

Sorry, I guess I wasn't clear - those functions execute on the server, because they're PHP functions. PHP never executes in the client's browser. If your script says then the server will upload it's resolv.conf file as "uploadedfile" on the second server.

the situation is 2 linux servers. one is running PHP, another is running JSP servlet

how can i let the user click a link or button to trigger the action to upload a file from PHP server to JSP server directly?

PHP server will use the HTTP "put" the file to the JSP server. and the JSP server will receive it as a normal upload like HTTP <form action="servlet" method="" enctype="">

is it possible to do that ??

Yes, the curl functions (link #1) will do that. Read through the docs, especially the setopt function, because that's where the functionality really is.

The best way to start would be to get file uploads working (from the PHP server preferably, if you have command line access) with the command line curl tool - this will give you a head start on figuring out which options you will need to set when you use the library functions. As soon as you can upload the file and have the JSP servlet receive it correctly, the rest is just grunt work.

how do i know my php server install curl or not ??

I go to php.net and see some curl example and i try to run at my server but see the following message.

example
====================================
<?php

$ch = curl_init("http://www.example.com/");
$fp = fopen("example_homepage.txt", "w");

curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);

curl_exec($ch);
curl_close($ch);
fclose($fp);
?>
====================================
message

oh ! sorry. I make a mistake. I change the file permission to apache and the url to google.com then the program can run again!!

thx for suggestion, I will try to use the curl lib Thx again!!!

Curl (the PHP library part) is definitely installed - you can tell because curl_setopt returned a warning message rather than an "unknown function" error. The first error is the source of the problem - your PHP script is probably running as a user that doesn't have permission to read the file you want to upload. Do you have shell access to this server?

How do i know which version I have

version of...?

phpinfo() would usually have most info you'd need on versions and such...

thx !!! I see it !! thx~~!
