Merhaba Arkadaşlar,
Tdk dan veri çekmeye çalışıyorum ama denemelerim başarısız oldu. Acaba nerede hata yapıyorum?

<?php 

$data = array( 
        'kelime' => 'deneme',  
        'gonder' => 'ARA',
        'ayn' => 'tam',
    );

$url = "http://tdk.gov.tr/index.php?option=com_bts&arama=kelime";

$useragent = 'Mozilla/5.0 (compatible; Googlebot/2.1; +[url]http://www.google.com/bot.html)';
$referer = 'http://www.google.com/'; 
$ch = curl_init(); 
$zaman = 0; 
curl_setopt ($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_POSTS, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $zaman); 
curl_setopt ($ch, CURLOPT_REFERER, $referer); 
curl_setopt ($ch, CURLOPT_USERAGENT, $useragent); 
$sonuc = curl_exec($ch); 
curl_close($ch); 
echo $sonuc; 




?>
