cURL in PHP Basecamp API "PUT"

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 ([email protected])");
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($ch, CURLOPT_USERAGENT, 'User-Agent : Holy Grail     ([email protected])');
    curl_setopt($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);

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 ([email protected])' \
  -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))                                                                       
);
