cURL in PHP Basecamp API "PUT" - php

Question

I am trying to edit an existing Basecamp project via the new Basecamp Api. I am receiving this error:
lexical error: malformed number, a digit is required after the minus sign. --------------- ---------------6 (right here) ------^
My Code:
$ch = curl_init();
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_URL, 'https://basecamp.com/****/api/v1/projects/****.json');
curl_setopt($ch, CURLOPT_USERAGENT, "User-Agent : Holy Grail (user#example.com)");
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");
curl_setopt($ch, CURLOPT_POSTFIELDS, array("name" => "from cURL"));
$result = curl_exec($ch);
echo $result;
curl_close($ch);
if ($result == false) {
echo "Fetch failed" ;
}
else {
$obj = json_decode($result, true);
}
//var_dump($obj);
?>
I'm sure I'm just doing something stupid, but any help is appreciated.
Thanks!
UPDATE
What I have now:
$username = 'user';
$password = 'pass';
$data = json_encode(array("name" => "from cURL"));
$ch = curl_init();
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
curl_setopt($ch, CURLOPT_URL, 'https://basecamp.com/****/api/v1/projects/*****.json');
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_PUT, 1);
curl_setopt($ch, CURLOPT_USERAGENT, 'User-Agent : Holy Grail (user#example.com)');
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type :application/json',
'Content-Length: ' .strlen($data)));
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$result = curl_exec($ch);
echo $result;
curl_close($ch);
if ($result == false) {
echo "Fetch failed" ;
}
else {
$obj = json_decode($result, true);
}
//var_dump($obj);
?>
</body>

BasecampAPI accepts only JSON data, you can see here in -d parameter -
curl -u username:password \
-H 'Content-Type: application/json' \
-H 'User-Agent: MyApp (yourname#example.com)' \
-d '{ "name": "My new project!" }' \
https://basecamp.com/999999999/api/v1/projects.json
So you're not sending JSON data in this line -
curl_setopt($ch, CURLOPT_POSTFIELDS, array("name" => "from cURL"));
Remove the CUSTOMREQUEST option and add CURLOPT_PUT. Modify your code to -
$data_string = json_encode(array("name" => "from cURL"));
...
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_PUT, True);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string))
);
