 <?php
 $base = "https://www.sanarate.ir/default.aspx";
 $curl = curl_init();
 curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
 curl_setopt($curl, CURLOPT_HEADER, false);
 curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
 curl_setopt($curl, CURLOPT_URL, $base);
 curl_setopt($curl, CURLOPT_REFERER, $base);
 curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
 curl_setopt($curl, CURLOPT_USERAGENT, "spider");
 $str = curl_exec($curl);
 print_r($str);
 curl_close($curl);
