Unable to upload file to box using Api in php - php

Question

I'm unable to upload file on box using php. I've tried all the contents which I've found on stackOverflow but never got success. Even I've tried https://github.com/golchha21/BoxPHPAPI/blob/master/README.md Client but still got failure. Can anyone help me how to upload file on box using php curl.
$access_token = 'xGjQY2XU0bmOEwVAdkqiZTsGuFyFuqzU';
$url = 'https://upload.box.com/api/2.0/files/content';
$headers = array("Authorization: Bearer $access_token"
. "Content-Type:multipart/form-data");
$filename = 'file.jpg';
$name = 'file.jpg';
$parent_id = '0';
$post = array('filename' => "#" . realpath($filename), 'name' => $name,
'parent_id' => $parent_id);
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_VERBOSE, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$response = curl_exec($ch);
var_dump($response);
Even I've used this request too...
$localFile = "file.jpg";
$fp = fopen($localFile, 'r');
$access_token = '00hsilvu9LrAsKQ8iDzXZAAieSLrjzX9';
$url = 'https://upload.box.com/api/2.0/files/content';
$curl = curl_init();
$cfile = new CURLFILE($localFile, 'jpg', 'Test-filename.jpg');
$data = array();
//$data["TITLE"] = "$noteTitle";
//$data["BODY"] = "$noteBody";
//$data["LINK_SUBJECT_ID"] = "$orgID";
//$data["LINK_SUBJECT_TYPE"] = "Organisation";
$data['filename'] = "file.jpg";
$data['parent_id'] = 0;
curl_setopt_array($curl, array(
CURLOPT_UPLOAD => 1,
CURLOPT_INFILE => $fp,
CURLOPT_NOPROGRESS => false,
CURLOPT_BUFFERSIZE => 128,
CURLOPT_INFILESIZE => filesize($localFile),
CURLOPT_URL => $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 => $data,
CURLOPT_HTTPHEADER => array(
"Authorization: Bearer 00hsilvu9LrAsKQ8iDzXZAAieSLrjzX9",
"Content-Type:multipart/form-data"
),
));
$response = curl_exec($curl);
$info = curl_getinfo($curl);
$err = curl_error($curl);
curl_close($curl);
var_dump($info);
$req_dump = print_r($response, true);
file_put_contents('box.txt', $req_dump, FILE_APPEND);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
And in response I always got an empty string.
Please tell me what am I doing wrong?

I'm using Box PHP Client for creation of folders, uploading of files and then sharing of uploaded files using this client.
https://github.com/golchha21/BoxPHPAPI
But this client's uploading file wasn't working... then I dig into it and I found something missing into this method.
/* Uploads a file */
public function put_file($filename, $name ,$parent_id) {
$url = $this->build_url('/files/content', array(), $this->upload_url);
if(isset($name)){
$name = basename($filename);
}
$params = array('filename' => "#" . realpath($filename), 'name' => $name , 'parent_id' => $parent_id, 'access_token' => $this->access_token);
return json_decode($this->post($url, $params), true);
}
Just put forward slash after # sign. Like this, Then I'll start working
/* Uploads a file */
public function put_file($filename, $name ,$parent_id) {
$url = $this->build_url('/files/content', array(), $this->upload_url);
if(isset($name)){
$name = basename($filename);
}
$params = array('filename' => "#/" . realpath($filename), 'name' => $name , 'parent_id' => $parent_id, 'access_token' => $this->access_token);
return json_decode($this->post($url, $params), true);
}
