$file='http://blog.163.com/interface.php';

$condition='limit=12&count='.$usernum;

$data17=getblogdata($domain,$condition,$file);

    }else{  
      while (!feof($fp)) {

       $res = fgets ($fp, 204800);  
      }  
     }  
     fclose ($fp);

}  

2.GET请求

$url = 'http://www.xxx.com/interface.php?cpid='.$cpid.'&qid='.$qid;

$_result = SendGET($url);

print_r($_result);

function SendGET($_url){
  $url = parse_url($_url);

    fputs($fp,"Host: ".$url['host']."\n");
    fputs($fp,"Content-type: application/x-www-form-urlencoded\n");
    fputs($fp,"Connection: close\n\n");
    $line = fgets($fp,1024);
    if(!eregi("^HTTP/1\.. 200", $line)) return;
    else{
