snoopy是一个php类，用来模仿web浏览器的功能，它能完成获取网页内容和发送表单的任务。
下面是它的一些特征：
1、方便抓取网页的内容
2、方便抓取网页的文字（去掉HTML代码）
3、方便抓取网页的链接
4、支持代理主机
5、支持基本的用户/密码认证模式
6、支持自定义用户agent,referer,cookies和header内容
7、支持浏览器转向，并能控制转向深度
8、能把网页中的链接扩展成高质量的url（默认）
9、方便提交数据并且获取返回值
10、支持跟踪HTML框架（v0.92增加）
11、支持再转向的时候传递cookies

下面是简单的例子，比如说我们抓取我的blog的文字

<?php
include "Snoopy.class.php";
$snoopy = new Snoopy;
$snoopy->fetchtext("https://www.gcpng.com");
echo $snoopy->results;
?>
<?php

include "Snoopy.class.php";
$snoopy = new Snoopy;
$snoopy->fetchlinks("https://www.gcpng.com");
print_r($snoopy->results);
?>

<?php

include "Snoopy.class.php";
$snoopy = new Snoopy;

$snoopy->fetchtext("https://www.php.net/");
print $snoopy->results;

$snoopy->fetchlinks("https://www.phpbuilder.com/");
print $snoopy->results;

$submit_url = "https://lnk.ispi.net/texis/scripts/msearch/netsearch.html";

$submit_vars["q"] = "amiga";
$submit_vars["submit"] = "Search!";
$submit_vars["searchhost"] = "Altavista";

$snoopy->submit($submit_url,$submit_vars);
print $snoopy->results;

$snoopy->maxframes=5;
$snoopy->fetch("https://www.ispi.net/");
echo "
 ";
    echo htmlentities($snoopy->results[0]);
    echo htmlentities($snoopy->results[1]);
    echo htmlentities($snoopy->results[2]);


include "Snoopy.class.php";
$snoopy = new Snoopy;

$snoopy->user = "joe";
$snoopy->pass = "bloe";

if($snoopy->fetch("https://www.slashdot.org/"))
{
echo "response code: ".$snoopy->response_code."
";
while(list($key,$val) = each($snoopy->headers))
echo $key.": ".$val."
";
echo "

";

例子: 展示所有属性的功能:

include "Snoopy.class.php";
$snoopy = new Snoopy;

$snoopy->proxy_host = "my.proxy.host";
$snoopy->proxy_port = "8080";

$snoopy->agent = "(compatible; MSIE 4.01; MSN 2.5; AOL 4.0; Windows 98)";
$snoopy->referer = "https://www.microsnot.com/";

$snoopy->cookies["SessionID"] = 238472834723489l;
$snoopy->cookies["favoriteColor"] = "RED";

$snoopy->rawheaders["Pragma"] = "no-cache";

$snoopy->maxredirs = 2;
$snoopy->offsiteok = false;
$snoopy->expandlinks = false;

$snoopy->user = "joe";
$snoopy->pass = "bloe";

if($snoopy->fetchtext("https://www.phpbuilder.com"))
{
while(list($key,$val) = each($snoopy->headers))
echo $key.": ".$val."
";
echo "

";

echo "
";

例子: 抓取框架内容并展示结果：

include "Snoopy.class.php";
$snoopy = new Snoopy;

$snoopy->maxframes = 5;

if($snoopy->fetch("https://www.ispi.net/"))
{
echo "
