php模擬登陸的實現方法，這裡分別列舉兩種方法實現模擬登陸人人網。具體實例代碼如下：
（1）使用snoopy模擬登陸
<?php
set_time_limit(0);
require "Snoopy.class.php";
$snoopy=new Snoopy();
$snoopy->referer='http://www.renren.com/';
$snoopy->agent="Mozilla/5.0 (Windows NT 6.1; rv:22.0) Gecko/20100101 Firefox/22.0";
$submit_vars['email'] ='登陸賬號';
$submit_vars['password'] ='登陸密碼';
$url='http://www.renren.com/PLogin.do';//登陸數據提交的URL地址
$snoopy->submit($url,$submit_vars);
$snoopy->fetch("http://www.renren.com/");//希望獲取的頁面數據
echo $snoopy->results;//www.phpernote.com
（2）使用curl模擬登陸
<?php
set_time_limit(0);
$cookie_file=tempnam('./tmp','cookie');//tmp目錄需要先建立好
$ch=curl_init();
$login_url='http://www.renren.com/PLogin.do';
$curlPost="email=登陸賬號&password=登陸密碼";
curl_setopt($ch,CURLOPT_URL,$login_url);
//啟用時會將頭文件的信息作為數據流輸出
curl_setopt($ch,CURLOPT_HEADER,0); //設定是否輸出頁面內容
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_POST,1); //設置請求發送方式，post或get，CURLOPT_POST或CURLOPT_GET
curl_setopt($ch,CURLOPT_POSTFIELDS,$curlPost);
curl_setopt($ch,CURLOPT_COOKIEJAR,$cookie_file); //保存cookie
curl_exec($ch);
curl_close($ch);
$ch=curl_init();
$login_url2="http://www.renren.com/";
curl_setopt($ch,CURLOPT_URL,$login_url2);
curl_setopt($ch,CURLOPT_HEADER,0);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,0);
curl_setopt($ch,CURLOPT_COOKIEFILE,$cookie_file); //讀取cookie
curl_exec($ch);
curl_close($ch);
