how to upload file using curl with PHP [closed]

Question

I want to know how to upload file using cURL or anything else in PHP. I have searched in google many times but no results.

In other words, the user sees a file upload button on a form, the form gets posted to my php script, then my php script needs to re-post it to another script (eg on another server).

I have this code to receive the file and upload it

code :

echo"".$_FILES['userfile'].""; $uploaddir = './'; $uploadfile = $uploaddir . basename($_FILES['userfile']['name']); if ( isset($_FILES["userfile"]) ) {     echo '<p><font color="#00FF00" size="7">Uploaded</font></p>';     if (move_uploaded_file ($_FILES["userfile"]["tmp_name"], $uploadfile)) echo $uploadfile;     else echo '<p><font color="#FF0000" size="7">Failed</font></p>'; } 

I want the code to send the file to receiver file.

Use:

if (function_exists('curl_file_create')) { // php 5.5+   $cFile = curl_file_create($file_name_with_full_path); } else { //    $cFile = '@' . realpath($file_name_with_full_path); } $post = array('extra_info' => '123456','file_contents'=> $cFile); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL,$target_url); curl_setopt($ch, CURLOPT_POST,1); curl_setopt($ch, CURLOPT_POSTFIELDS, $post); $result=curl_exec ($ch); curl_close ($ch);

Important hint for PHP 5.5+:

Now we should use https://wiki.php.net/rfc/curl-file-upload but if you still want to use this deprecated approach then you need to set curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);
