Merhaba arkadaşlar, cURL ile web sitesinden veri çekmeye çalışıyorum, localhost üzerinden sorunsuz çekiyor ama sunucuda çekmek istediğimde boş değer dönüyor.
Kullanıdğım fonksiyon budur;

function curlKullan($url){
	$curl = curl_init();
	curl_setopt($curl,CURLOPT_REFERER,'http://google.com');
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER,true);     // return web page
    curl_setopt($curl, CURLOPT_HEADER,true);     //return headers in addition to content
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION,true);     // follow redirects
    curl_setopt($curl, CURLOPT_ENCODING,"utf-8");       // handle all encodings
    curl_setopt($curl, CURLOPT_AUTOREFERER,true);    // set referer on redirect
    curl_setopt($curl, CURLOPT_CONNECTTIMEOUT,120);      // timeout on connect
    curl_setopt($curl, CURLOPT_MAXREDIRS,10);       // stop after 10 redirects
    curl_setopt($curl, CURLINFO_HEADER_OUT,true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER,false);    // Disabled SSL Cert checks
    curl_setopt($curl, CURLOPT_POST,0);
	curl_setopt($curl,CURLOPT_USERAGENT, $_SERVER["HTTP_USER_AGENT"]);	
	$cikti = curl_exec($curl);
	curl_close($curl);
	$cikti = str_replace(array("n","t","r"), null, $cikti);
	return $cikti;
}
$url = curlKullan('https://www.cctvcalculator.net/api/calculation.php?jsoncallback=jQuery214038336959030315054_1585735346782&calc=storage&security=a9f5523fe5&motion=1.00&resolution=640-360&codec=340&cameras=1&mfps=1&nfps=10&days=1');
print_r($url);
