How to upload file into target directory with curl?

Question

There is a file "/home/test.mp4" in my local machine,

I want to upload it into /var/www/ok.mp4 (the name changed when uploaded it). All the source file and target file are in the local machine.

How to fix my partial code ,to add something or to change something ?

<?php  $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string);  curl_exec($ch);  ?> 

Think to Ram Sharma, the code was changed as the following:

<?php $request = curl_init('http://127.0.0.1/'); curl_setopt($request, CURLOPT_POST, true); curl_setopt(     $request,     CURLOPT_POSTFIELDS,     array(       'file' => '@' . realpath('/home/test.mp4')     )); curl_setopt($request, CURLOPT_RETURNTRANSFER, true); echo curl_exec($request); // close the session curl_close($request); ?> 

An error message occur:

It works!
This is the default web page for this server.
The web server software is running but no content has been added, yet.

I have test with ftp_put,code1 works fine.

code1:

<?php     set_time_limit(0);     $host = 'xxxx';     $usr = 'yyyy';     $pwd = 'zzzz';     $src = 'd:/upload.sql';     $ftp_path = '/public_html/';     $des = 'upload_ftp_put.sql';     $conn_id = ftp_connect($host, 21) or die ("Cannot connect to host");     ftp_login($conn_id, $usr, $pwd) or die("Cannot login");     $upload = ftp_put($conn_id, $ftp_path.$des, $src, FTP_ASCII);      print($upload); ?> 

The file d:/upload.sql in my local pc can be uploaded into my_ftp_ip/public_html/upload_ftp_put.sql with code1.
Now i rewite it with curl into code2.

code2:

<?php   set_time_limit(0);   $ch = curl_init();   $host = 'xxxx';   $usr = 'yyyy';   $pwd = 'zzzz';   $src = 'd:/upload.sql';   $ftp_path = '/public_html';   $dest = 'upload_curl.sql';   $fp = fopen($src, 'r');   curl_setopt($ch, CURLOPT_URL, 'ftp://user:pwd@host/'.$ftp_path .'/'. $dest);   curl_setopt($ch, CURLOPT_UPLOAD, 1);   curl_setopt($ch, CURLOPT_INFILE, $fp);   curl_setopt($ch, CURLOPT_INFILESIZE, filesize($src));   curl_exec ($ch);   $error_no = curl_errno($ch);   print($error_no);   curl_close ($ch); ?> 

The error info output is 6 .Why can't upload my local file into the ftp with curl?How to fix it?

Answer 1

Use copy():

copy('/home/test.mp4', '/var/www/ok.mp4'); 

It does not make sense to run the file through the network stack (which is what cURL does), on any protocol (HTTP, FTP, …), when the manipulation can be done locally, through the file system. Using network is more complicated and error-prone.

Answer 2

It is a low level error.

curl_setopt($ch, CURLOPT_URL, "ftp://$usr:$pwd@$host$ftp_path/$dest");
