$_SESSION['username_'.$Site_ID]                     = $username;    
$_SESSION['password_'.$Site_ID]                     = $password;

$_SESSION['contact_job_title_'.$Site_ID]                     = $contact_job_title;    
$_SESSION['contact_given_name_'.$Site_ID]             = $contact_given_name;    
$_SESSION['contact_family_name_'.$Site_ID]            = $contact_family_name;            
$_SESSION['contact_address_1_'.$Site_ID]             = $contact_address_1;    
$_SESSION['contact_address_2_'.$Site_ID]             = $contact_address_2;    
$_SESSION['contact_postcode_'.$Site_ID]             = $contact_postcode;            
$_SESSION['contact_city_'.$Site_ID]                    = $contact_city;    
$_SESSION['contact_county_'.$Site_ID]                = $contact_county;    
$_SESSION['contact_country_id_'.$Site_ID]            = $contact_country_id;    
$_SESSION['contact_email_'.$Site_ID]                = $contact_email;    
$_SESSION['contact_telephone_'.$Site_ID]            = $contact_telephone;    
$_SESSION['contact_mobile_telephone_'.$Site_ID]        = $contact_mobile_telephone;
$_SESSION['sams_puid_'.$Site_ID]                    = $sams_puid; 

Thanks in advance from a new php learner

Might I suggest using an additional array dimension? It would probably make things neater for you.

$_SESSION['username'][$Site_ID] = $username;
// or:
$_SESSION[$Site_ID]['username'] = $username;

Thanks, I am going to implement this one "$_SESSION['username'][$Site_ID] = $username;" and see how it goes, the reason why i am using is to be able to open more than one website in a browser by keeping there session separate from each other so if i log out from website it will not affect the other site, my present code "$_SESSION['username_'.$Site_ID] = $username; " is working fine but i think it is not professional way to do,
One thing i need to clarify is "$_SESSION['username']["{$Site_ID}"] = $username; note the " { } " inside the array rather than just the variable is good idea than "$_SESSION['username'][$Site_ID] = $username;" because site_id will be different for every site opened in the browser.

Many thanks.

There is no reason in this case to put quotes or curly braces around the $Site_ID variable when being used as an array key. While it will work, all it accomplishes is a tiny bit of extra processing by the PHP parser. In the end, it's still just the variable itself that needs to be parsed.
