HTTP upload to dropbox and share - php

Question

I have dropbox file upload. The following code is working fine, but I want to automatically share with "anyone with the link" and return the sharing link so I can have it to reference in my program.
PHP CODE
$DROPBOX_path = 'folder/subfolder1/subfolder2/user.png';
$path = './tmp/user.png';
$fp = fopen($path, 'rb');
$size = filesize($path);
$cheaders = array('Authorization: Bearer '. $DROPBOX_ACCESS_TOKEN,
'Content-Type: application/octet-stream',
'Dropbox-API-Arg: '.
json_encode(
array(
"path"=> '/'.$DROPBOX_path,
"mode" => "add",
"autorename" => false,
"mute" => true
)
)
);
$ch = curl_init('https://content.dropboxapi.com/2/files/upload');
curl_setopt($ch, CURLOPT_HTTPHEADER, $cheaders);
curl_setopt($ch, CURLOPT_PUT, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_INFILE, $fp);
curl_setopt($ch, CURLOPT_INFILESIZE, $size);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
echo $response;
curl_close($ch);
fclose($fp);
I have tried this but I get an error:
Error in call to API function "sharing/create_shared_link_with_settings": request body: could not decode input as JSON
$cheaders = array('Authorization: Bearer '. $DROPBOX_ACCESS_TOKEN,
'Content-Type: application/json',
'data: '.
json_encode(
array(
"path"=> '/'.$DROPBOX_path,
"settings" => array("requested_visibility" => "public")
)
)
);
$ch = curl_init('https://api.dropboxapi.com/2/sharing/create_shared_link_with_settings');
//$ch = curl_init('https://api.dropboxapi.com/1/shares/auto/');
curl_setopt($ch, CURLOPT_HTTPHEADER, $cheaders);
curl_setopt($ch, CURLOPT_PUT, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
echo $response;
curl_close($ch);
fclose($fp);

Answer 1

This fixed it
$parameters = array('path' => '/'.$DROPBOX_path);
$headers = array('Authorization: Bearer '.$DROPBOX_ACCESS_TOKEN,
'Content-Type: application/json');
$curlOptions = array(
CURLOPT_HTTPHEADER => $headers,
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => json_encode($parameters),
CURLOPT_RETURNTRANSFER => true,
CURLOPT_VERBOSE => true
);
$ch = curl_init('https://api.dropboxapi.com/2/sharing/create_shared_link_with_settings');
curl_setopt_array($ch, $curlOptions);
$response = curl_exec($ch);
echo $response;
curl_close($ch);
