Email Address Detection

[shapiro125]

If i have a newsletter and to unsubscribe you go to unsubscribe.php?Email=XXX, how can I program the page to automatically detect the email address when a link to the page is clicked on in an email?

You're passing a query string. Read the section of the manual dealing with variables from outside PHP.

I've searched through the manual and still can't find a solution.

1.i think the best solution is to
make a table with 2 fields :1-a uniq code for every email,2- the email. in email put a link unsubscribe.php?code=blabla&email=xxx;
if the user read the email and click the link unsubscrube ... , when the page unsubscribe is open you verify if $HTTP_GET_VARS["email"]&&$HTTP_GET_VARS["code"] is in table delete from table. (the script who send information is in crontab)

2.make a cookie where you put the email when the user subscribe and when the user click on unsubscribe u read email from the cookie. but if the user delete the cookie from his computer u can unsubscribe him only if he subscribe again
