I am Working on a Project, I need some clarification to share data between two sites in a high secure manner. Currently I am using Form Post to share data. But I think about if there is an option to get site-1 session-data from site-2, because I think using a session is more secure. I don't know how to use a sessions between two sites, but I hope someone here will know.

Like this:
Site 1 Coding

$_SESSION['cust_id'] = 'abc';  
$_SESSION['amount'] = '999';  

<a href=https://site2.com/direct.php?session_id=<?=$_SESSION['session_id']?>>Click Here</a>  

Site 2 Code in direct.php

$session_id = $_REQUEST['session_id'];  
$shared_data = XYZ_function($session_id);  

$cust_id = $shared_data['cust_id'];  
$amount = $shared_data['amount'];  

or is there any way to do the secure data sharing between two website other than form post, please tell me.

Thank you

It seems you're pretty heavy on security. If you need to share data from site 1 to site 2, you should do it through a single consumption bridge:

1). Click on a link on Site 1 to a handler file, let's call it redir.php.

2). Redir.php first checks the existing session data.

3). Redir.php writes relevant info into a DB row, along with some sort of identifier (say, an MD5 hash of the user ID + '_'+ current time), plus a 'consumed' flag, set false.

4). Redir.php does a 301 redirect to Site 2, along with the identifier.

5). Site 2 reads the relevant row out of the DB.

6). If the data is good and has not yet been 'consumed', return a success and mark the data as consumed.

7). If the data has been consumed, throw some sort of error.

There are more complex ways of doing this, but I think this handles what you're trying to do.
