PHP中使用socket方式GET、POST数据实例

1. 使用 PHP 获得网页内容 GET方式
复制代码 代码如下:
<"/";
 $fp = fsockopen($host, $port, $errno, $errstr, 30);
 if (!$fp)
 {
  echo "$errstr ($errno)<br />\n";
  return false;
 }
 else
 {
     $out = "GET $path HTTP/1.1\r\n";
     $out .= "Host: $host\r\n";
     $out .= "Connection: Close\r\n\r\n";
  $ret = "";
     fwrite($fp, $out);
     while (!feof($fp))
  {
         $ret .= fgets($fp, 128);
     }
     fclose($fp);
 }
 return true;
}
"codetitle">复制代码 代码如下:
<"/";
 $fp = fsockopen($host, $port, $errno, $errstr, 30);
 if (!$fp)
 {
     echo "$errstr ($errno)<br />\n";
  return false;
 }
 else
 {
     $out = "POST $path HTTP/1.1\r\n";
     $out .= "Host: $host\r\n";
  $out .= "Content-Type: application/x-www-form-urlencoded\r\n";
  $out .= "Content-Length: ".strlen($data)."\r\n";
     $out .= "Connection: Keep-Alive\r\n\r\n";
  $out .= $data;
  $ret = "";
     fwrite($fp, $out);
     while (!feof($fp))
  {
         $ret .= fgets($fp, 128);
     }
     fclose($fp);
 }
 return true;
}
"Connection: Keep-Alive\r\n\r\n";中的Keep-Alive改成Close
