How to fix 'CURLFile' function not found error?

I am trying to implement marketo create file rest API. But i am getting 'Class CURLFile not found' error due to my php version. So please help how i can use 'CURLFile' funtion in lower php or is their any another equivalent of same function. Please check my below code:-

<?php
$file = new CreateFile();
$file->file = new CURLFile("File.txt", "text/plain", "file");
$file->folder = new stdClass();
$file->folder->id = 5565;
$file->folder->type = "Folder";
$file->name = "Test File.txt";
print_r($file->postData());

class CreateFile
private $host = "CHANGE ME";
private $clientId = "CHANGE ME";
private $clientSecret = "CHANGE ME";
public $name;//name of file to create, required
public $file;//CURLFile of file to input
public $folder;//json object with two members, id and type(Folder or Program)
public $description;//option description of file
public $insertOnly;//boolean option to only perform an Insert

public function postData()
$url = $this->host . "/rest/asset/v1/files.json?access_token=" . $this->getToken();
$ch = curl_init($url);
$requestBody = $this->bodyBuilder();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('accept: application/json','Content-Type: multipart/form-data'));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $requestBody);
curl_getinfo($ch);
$response = curl_exec($ch);
return $response;


private function getToken()
$ch = curl_init($this->host . "/identity/oauth/token?grant_type=client_credentials&client_id=" . $this->clientId . "&client_secret=" . $this->clientSecret);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('accept: application/json',));
$response = json_decode(curl_exec($ch));
curl_close($ch);
$token = $response->access_token;
return $token;

private function bodyBuilder()
$requestBody = array("file" => $this->file, "name" => $this->name, "folder" => json_encode($this->folder));
if (isset($this->description))
$requestBody["description"] = $this->description;

if(isset($this->insertOnly))
$requestBody["insertOnly"] = $this->insertOnly;

return $requestBody;

replace $file->file = new CURLFile("File.txt", "text/plain", "file");

$file->file = new CURLFile("File.txt", "text/plain", "file");

with $file->file = "@File.txt;filename=file;type=text/plain";

$file->file = "@File.txt;filename=file;type=text/plain";

in php 5.5+ you need to set curl_setopt ($ch, CURLOPT_SAFE_UPLOAD, false);

curl_setopt ($ch, CURLOPT_SAFE_UPLOAD, false);

Check you PHP version.
CURLFile is only work for the PHP version => 5.5

PHP provides certain functionality by way of loadable modules. This is most often the case for things that require extra libraries, like libcurl. In order to use that functionality, the relevant module needs to be installed on your system, and a statement to load the relevant module needs to appear in your php.ini file.

php.ini

How you install the curl module depends on how you installed PHP; it may be as simple as installing the package, or it may require that you recompile all of PHP.

If you are using PHP version >=5.5 and a framework like Laravel, remember to add "" before CURLFILE.

File Upload w/o CURLFile Class in PHP Version < 5.5.0 don´t work. Update Your PHP Version to 5.5, 5.6, 7.0, 7.1. Then it works.
