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:

  <?php

  function socketGet($url, &$ret)

  {

  $urlArr = parse_url($url);

  $host = $urlArr['host'];

  $port = isset($urlArr['port'])?$urlArr['port']:80;

  $path = isset($urlArr['path'])?$urlArr['path']:"/";

  $fp = fsockopen($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;

  }

  ?>

  2. 使用 PHP 向页面 POST 数据

  

复制代码 代码如下:

  <?php

  function socketPost($url, $data, &$ret)

  {

  $urlArr = parse_url($url);

  $host = $urlArr['host'];

  $port = isset($urlArr['port'])?$urlArr['port']:80;

  $path = isset($urlArr['path'])?$urlArr['path']:"/";

  $fp = fsockopen($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;

  }

  ?>

  如果post报错,把$out .= "Connection: Keep-Alive\r\n\r\n";中的Keep-Alive改成Close
