不要心存侥幸，避免贪婪的心作怪，这会令你思考发生短路。如果你不是步步踏实，就容易掉入不切实际的冒险。

1. 使用 PHP 获得网页内容 GET方式



<?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



<?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;

}

?>
