json - PHP Curl and reseller domain availability checker -

i requesting data heart internet's domain availability checker using php curl function. have got working fine, there 1 thing not sure how working.

there incremental search option data retrieved when ready, rather waiting process finish. possible take advantage of using php , curl? document states:

incremental: optional, boolean. if true, results come in, in form of series of newline-separated json objects, see "incremental searching" below.

and also:

if want give fastest possible response, should use incremental searching. means instead of waiting results, try perform several searches @ once , output each result comes in. in same format non-incremental mode except no "complete" property , newline ("\n") @ end. once results have been produced, single json object should equivalent empty search result.

for example: {"lookup":[{"name":"example.org","reason":"registered","avail":0}]} {"lookup":[{"name":"example2.org","reason":"registered","avail":0}]} {"lookup":[],"premium":[],"category":[],"complete":1}

please note more 1 domain name per result in format.

my code follows:

$access_token = "mytoken"; $access_token_64 = base64_encode($access_token); $data = array("name" => array("domianexample.co.uk", "domianexample.com", "domainexample.net", "domianexampletwo.com", "domainexampletwo.net"), "incremental " => true); $data_string = json_encode($data);  $ch = curl_init('http://api.heartinternet.co.uk/cx/dac.cgi'); curl_setopt($ch, curlopt_customrequest, "post"); curl_setopt($ch, curlopt_postfields, $data_string); curl_setopt($ch, curlopt_returntransfer, true); curl_setopt($ch, curlopt_httpheader, array(     'authorization: bearer ' . $access_token_64,     'content-type: application/json',     'content-length: ' . strlen($data_string)) );  $result = curl_exec($ch); 

any or hints gratefully appreciated.
