还记得我的JavaScript吗？

Question

How would I properly write a script to set cookies to remember a user's username and password upon checking a checkbox on the login form?

Also, if this could be done in PHP please let me know.

Answer 1

In PHP, set a cookie with the session information (username, password) by copying the appropriate values from $_SESSION into $_COOKIE using set_cookie. When the user visits a page, check first for the existence of $_SESSION variables, then for $_COOKIE variables. If the $_COOKIE variables exist but the $_SESSION ones don't, copy from $_COOKIE into $_SESSION. (That is, if the user checks the box.)
