How to upload file to api via curl post - php

Question

This is the $_POST
Array
(
[name] => image.png
[type] => image/png
[tmp_name] => C:\xampp5\tmp\phpA637.tmp
[error] => 0
[size] => 16412
)
And here's the code:
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_PORT => "2403",
CURLOPT_URL => "http://".cfg('api_ip').":2403/sk_group/update_profile_pic", //url
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => "------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"data\"\r\n\r\n{\"groupId\":\"".$group."\",\"profile_pic\":\"".$name."\"}\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"profile_pic\"; filename=\"".$file."\"\r\nContent-Type: ".$type."\r\n\r\n\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW--",
CURLOPT_HTTPHEADER => array(
"SessionId: ".$_SESSION['session']."",
"VersionCode: ".cfg('version_code')."",
"content-type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
redirect("/meme/me/group"."?msg=".urldecode('Update icon group succes')."&type_msg=success");
}
i want to know how to $file to the image for success upload, cause $_POST only display the filename not with the fullpath.
Update
this is the full function in controller i have
function one()
{
$filename = $_FILES['icon']['name'];
$filedata = $_FILES['icon']['tmp_name'];
$filetype = $_FILES['icon']['type'];
two($_POST['group'], $filename, $filedata, $filetype);
}
this function on my helper
function two($group, $name, $file, $type)
{
$cFile = new CURLFile($file,$type,$name);
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_PORT => "2403",
CURLOPT_URL => "http://".cfg('api_ip').":2403/sk_group/update_profile_pic",
CURLOPT_HEADER => true,
CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_POST => true,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => "------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"data\"\r\n\r\n{\"groupId\":\"".$group."\",\"profile_pic\":\"".$name."\"}\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW\r\nContent-Disposition: form-data; name=\"profile_pic\"; filename=\"".$cFile."\"\r\nContent-Type: ".$type."\r\n\r\n\r\n------WebKitFormBoundary7MA4YWxkTrZu0gW--",
CURLOPT_HTTPHEADER => array(
"SessionId: ".$_SESSION['session']."",
"VersionCode: ".cfg('version_code')."",
"content-type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW"
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
redirect("/meme/me/group"."?msg=".urldecode('Update icon group succes')."&type_msg=success");
}
}
still with same question like i asking..., where the file? and how to post it until success?

I have posted the same answer here
From PHP 5.5 and above the CURL will use CURL File to upload the files, for the lower PHP version, you need to manually generate the form boundary and then send the file. The following code sample handles both the cases.
For ease, here's the main part:
<?php
$file = "websites.txt";
upload_with_compatibility($file);
function upload_with_compatibility($file){
if (version_compare(phpversion(), '5.5', '>=')) {
echo "Upload will be done using CURLFile\n";
upload($file); //CURL file upload using CURLFile for PHP v5.5 or greater
}else{
echo "Upload will be done without CURLFile\n";
compatibleUpload($file); //CURL file upload without CURLFile for PHP less than v5.5
}
}
//Upload file using CURLFile
function upload($file){
$target = "http://localhost:8888/upload_file.php";
$host = parse_url($target);
$cFile = new CURLFile($file,'text/plain', $file);
$data = array(
'log_file' => $cFile,
);
//you can play around with headers, and adjust as per your need
$agent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.101 Safari/537.36';
$curlHeaders = array(
'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8',

'Connection: Keep-Alive',

'Referer: http://localhost:8888/upload.php', //you can change referer, if you want or remove it
