How to convert curl file post from command line into PHP cURL - php

Question

I'm trying to post files to a 3rd party API from my PHP app.
This works from the command line:
curl -F "file=#move_file.MOV" "https://upload.wistia.com?project_id=pbmcmua3ot&username=api&api_password=xxxxx_apikey_yyyyy"
But I can't get it to work using PHP's curl:
$data = array(
'username' => $username,
'api_password' => $api_password,
'file' => fopen($tmp_filename, 'r'),
'project_id' => $project_hashed_id,
);
$ch = curl_init();
//curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, "https://upload.wistia.com" );
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 86400); // 1 Day Timeout
curl_setopt($ch, CURLOPT_INFILE, fopen($tmp_filename, 'r') );
curl_setopt($ch, CURLOPT_NOPROGRESS, false);
curl_setopt($ch, CURLOPT_BUFFERSIZE, 128);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($tmp_filename));
curl_setopt($ch, CURLOPT_VERBOSE, 1); //for debugging
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
$result = curl_exec($ch);
curl_close($ch);
return json_decode($result);
I think CURLOPT_INFILE is the problem but I'm not sure. Thanks in advance for any help you can give me.
UPDATE1
$data = array(
'username' => $username,
'api_password' => $api_password,
'file' => '#'.$tmp_filename,
'project_id' => $project_hashed_id,
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, "https://upload.wistia.com" );
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 86400); // 1 Day Timeout
curl_setopt($ch, CURLOPT_NOPROGRESS, false);
curl_setopt($ch, CURLOPT_BUFFERSIZE, 128);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize($tmp_filename));
curl_setopt($ch, CURLOPT_VERBOSE, 1); //for debugging
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($ch);
curl_close($ch);
return json_decode($result);
UPDATE 2 (Working)
$data = array(
'api_password' => $api_password,
'file' => '#'.$tmp_filename,
'project_id' => $project_id
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_URL, "https://upload.wistia.com" );
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec($ch);
curl_close($ch);

You don't need to open a handle for curl, just have
$data = array(
'file' => '#move_file.MOV'
);
Curl will see the # and treat it as a file upload attempt. You also don't have to do http_build_query() either. Curl can accept an array directly and do the query building itself:
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
