如何使用php中的curl将文件从本地上传到服务器?

I want to upload the file from local to server using curl in php and without using the form (which is html).

My php version is 5.2.6.

I have tried many different way and make many research about (upload file to server using curl in php), but the solution in google cannot solve my problem.

Below is my code:

// open file descriptor
$fp = fopen ("user.com/user/fromLocal.txt", 'w+') or die('Unable to write a file'); 

// file to download
$ch = curl_init('C:/wamp/www/user/fromLocal.txt');
// enable SSL if needed
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 

// output to file descriptor
curl_setopt($ch, CURLOPT_FILE, $fp);          
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
// set large timeout to allow curl to run for a longer time
curl_setopt($ch, CURLOPT_TIMEOUT, 1000);     
curl_setopt($ch, CURLOPT_USERAGENT, 'any');
// Enable debug output
curl_setopt($ch, CURLOPT_VERBOSE, true);

echo $ch;
echo $fp;
curl_exec($ch);
curl_close($ch);                               
fclose($fp);

Expected output:

The file can upload to server and view.

Actual output:

Unable to write the file

    I think you miss important information.

    fopen ("user.com/user/fromLocal.txt", 'w+')
    

    this means nothing. To send a file to the server the server has to be configured to accept a POST request and you have to send the file through that endpoint.

    If you have a form, do you send it to: "user.com/user/fromLocal.txt" ?? You have to create the form data with curl and send it to a server ready to accept your request. There are different ways to accomplish that. And the most simple is exactly to send a form using curl and not the HTML. But absolutly you cannot write a file like that in a server.
