PHP Script to login to external web pages

[matthewlesh]

Hey there everyone..

 

This is something which i have wanted to be able to do for ages,

 

Well anyway what i would like this script to do is :

 

  1. Login Using POST to an SSL Server (The login system uses cookies)

  3. Go to a page after login and get the information into a variable

 

Any help with this would be very great.

What CMS are you using?

look into the curl functions

 

OK,

 

I've had a look around a bit... but now i have come into another problem...

 

I don't know how to use curl and there doesn't seem to be much around about it.

 

What i need to do now it work out how to :

 

  1. Go to a page and pick up some cookies

  2. Send post information to another page with those cookies being sent

  3. Set more cookies after that form has been sent

  4. View a page with the cookies being sent

 

I have had a look at a few page and found out how to just do the post part.. but everything else i am extremely confused about:

define('POSTURL', '<website to send post>');
define('POSTVARS', 'send=yes&q=$data');  // POST VARIABLES TO BE SENT

// INITIALIZE ALL VARS
$Email='';
$ch='';
$Rec_Data='';
$Temp_Output='';

if($_SERVER['REQUEST_METHOD']==='POST') {  // REQUIRE POST OR DIE

$ch = curl_init(POSTURL);
curl_setopt($ch, CURLOPT_POST      ,1);
curl_setopt($ch, CURLOPT_POSTFIELDS    ,POSTVARS);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION  ,1); 
curl_setopt($ch, CURLOPT_HEADER      ,0);  // DO NOT RETURN HTTP HEADERS 
curl_setopt($ch, CURLOPT_RETURNTRANSFER  ,1);  // RETURN THE CONTENTS OF THE CALL
$Rec_Data = curl_exec($ch);

ob_start();
header("Content-Type: text/html");
$Temp_Output = ltrim(rtrim(trim(strip_tags(trim(preg_replace ( "/\s\s+/" , " " , html_entity_decode($Rec_Data)))),"\n\t\r\h\v\0 ")), "%20");
$Temp_Output = ereg_replace (' +', ' ', trim($Temp_Output));
$Temp_Output = ereg_replace("[\r\t\n]","",$Temp_Output);
$Temp_Output = substr($Temp_Output,307,200);
echo $Temp_Output;
$Final_Out=ob_get_clean();
echo $Final_Out;  
curl_close($ch);
} else die('Hacking attempt Logged!');

exit;
