PHP Session Handling - Without Cookies
|
|
If cookies are disabled at the browser, the above example cannot work. This is because although the session file that stores all the variables is kept at the server, a cookie is still needed at the browser to store the session ID that is used to identify the session and its associated session file. The most common way around this would be to explicitly pass the session ID back to the server from the browser as a query parameter in the URL.
For example, the PHP script generates requests subsequent to the start_session call in the following format: http://www.yourhost.com/yourphpfile.php?PHPSESSID=[actual session ID]
The following are excerpts that illustrate the discussion:
Manually building the URL:
$url = "http://www.yoursite.com/yourphppage.php?PHPSESSID=" . session_id(); [a href="[?=$url ?]"]Anchor Text[/a]
Building the URL using SID:
[a href="http://www.yoursite.com/yourphppage.php?[?=SID ?]"]Anchor Text[/a]
