如何在php中将文件从一台服务器写入另一台服务器？

Question

Is it possible to write a file from on server to another server?

I have 2 domains both are on diffrent web servers

http://example1.com is on godady and http://example2.com is on a free webhost eu5.org ,

I want to write htaccess file of http://example1.com from http://example2.com .

my code in example2.com

$code =$_POST["cd"];

if (empty($code)) {
    echo "Could not insert data!";
} else {
    $file = fopen("http://server2.com/.htaccess", "w");

    echo fwrite($file, $code);
    fclose($file);
}

It does'nt rewrite the .htaccess file and no php error. file permision of example1/.htaccess is 777.

Any idea?

The short answer is:

"Yes. It possible to write a file from on server to another server"

To write any file to any server across the network, you need to:

1) decide on a protocol (for example, ftp ), then

2) instantiate a "listener" on the host to accept client requests for that protocol (for example, installing WinSCP on your Windows host)

Since you're writing in PHP - and since PHP is already using a protocol (HTTP) and already has a "listener" (your web server) -then why not just write a PHP app to accept files for upload, and send files for download?

Here's a simple example:

Whatever you choose to do, make sure it's secure . In particular, you should not be able to "re-write .htaccess", and you should not be able to read or write to any arbitrary directory.
