CodePudding user response：

A simple way is to create a cookie with a very long time, like 10 years. But be aware that the user can clear his cookies from time to time.

To create the cookie you do:

setcookie("ButtonSaved", 'My Button Text', time() 3600*24*365*10, '/')

And to show the cookie value, you do:

if (isset($_COOKIE["ButtonSaved"])) {

    echo $_COOKIE["ButtonSaved"];
}
else {
    //generate button text again
}
