Issue in Downloading File In Dropbox Version 2 Php Api - php

Question

Hy Everyone,
I am using this code to download file from Dropbox Version 2 Php Api.But I don't get success yet in File downloading.Lets have a look on the script which i am using
function dbx_get_file($token, $in_filepath, $out_filepath)
{
$out_fp = fopen($out_filepath, 'w+');
if ($out_fp === FALSE)
{
echo "fopen error; can't open $out_filepath\n";
return (NULL);
}
$url = 'https://content.dropboxapi.com/2/files/download';
$header_array = array(
'Authorization: Bearer ' . $token,
'Content-Type:',
'Dropbox-API-Arg: {"path":"' . $in_filepath . '"}'
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header_array);
curl_setopt($ch, CURLOPT_FILE, $out_fp);
$metadata = null;
curl_setopt($ch, CURLOPT_HEADERFUNCTION, function ($ch, $header) use (&$metadata)
{
$prefix = 'dropbox-api-result:';
if (strtolower(substr($header, 0, strlen($prefix))) === $prefix)
{
$metadata = json_decode(substr($header, strlen($prefix)), true);
}
return strlen($header);
}
);
$output = curl_exec($ch);
if ($output === FALSE)
{
echo "curl error: " . curl_error($ch);
}
curl_close($ch);
fclose($out_fp);
return($metadata);
} // dbx_get_file()
Calling this Function Here.
dbx_get_file("<Access-token>", '/Screenshot_1.png', 'Screenshot_1.png');
I also replaced this "Access-token" with my Dropbox O-auth 2 Access Token.
Please suggest me the answer what i am doing wrong?Or is there any other way to download File from Dropbox using DropBox Version 2 PHP Api.
Thanks

I have done it using Requests Library https://github.com/rmccue/Requests/
Here is my Code
include('Requests-master/library/Requests.php');
Requests::register_autoloader();
$token="Your Access Token is here";
$response =
Requests::post("https://content.dropboxapi.com/2/files/download", array(
'Authorization' => "Bearer ".$token,
'Dropbox-Api-Arg' => json_encode(array('path' => '/Screenshot_1.png')),
));
$fileContent = $response->body;
/*Download the file using file_put_contents method*/
file_put_contents("Screenshot_1.png",$fileContent);
$metadata = json_decode($response->headers['Dropbox-Api-Result'], true);
echo "File " . $metadata["name"] . " has the rev " . $metadata["rev"] . ".\n";
File is downloading Successfully... :)
