Writing the following curl in PHP - php

Question

How would I write the following Curl in PHP?
I need to automate this process in php.
$ curl -F file=#/Users/alunny/index.html -u andrew.lunny#nitobi.com -F 'data={"title":"API V1 App","package":"com.alunny.apiv1","version":"0.1.0","create_method":"file"}' https://build.phonegap.com/api/v1/apps
Here is the link to the Phonegap Build API.
http://docs.build.phonegap.com/en_US/developer_api_write.md.html#_post_https_build_phonegap_com_api_v1_apps
Any help would be greatly appreciated.
This is what I have tried so far...
<?php
$url = 'https://build.phonegap.com/api/v1/apps';
$file = 'mobilecontainer.zip';
$fields = array(
'title' => 'Test App',
'create_method' => 'file',
'private' => 'false'
);
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string, '&');
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
curl_setopt($ch,CURLOPT_SAFE_UPLOAD, 'true');
$result = curl_exec($ch);
print_r($result);
curl_close($ch);

Answer 1

You use CURL options improperly.
CURLOPT_SAFE_UPLOAD option disables support for the # prefix for
uploading files in CURLOPT_POSTFIELDS which is exactly what you
need to use.
CURLOPT_POST option expects a boolean value (true or false),
although count($fields) in your case will be evaluated to true
anyway.
-F option in the source curl command forces Content-Type value
to multipart/form-data. This mean that in PHP you have to pass
data to CURLOPT_POSTFIELDS as array. This array should contain two
elements: 'data' - json-encoded data, and 'file' - link to file
to upload.
So the code should look like this:
$url = 'https://build.phonegap.com/api/v1/apps';
$data = array(
'title' => 'Test App',
'package' => 'com.alunny.apiv1',
'create_method' => 'file',
'version' => '0.1.0',
);
$post = array(
'data' => json_encode($data),
'file' => '#mobilecontainer.zip',
);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_POSTFIELDS, $post);
$result = curl_exec($ch);
curl_close($ch);
print_r($result);
