这篇文章主要介绍了PHP中使用socket方式GET、POST数据实例,本文分别给出GET方式和POST方式的代码实例,需要的朋友可以参考下

1. 使用 PHP 获得网页内容 GET方式，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，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;

}

?>
