PHP Cookie practical tutorial

Two days ago we shared how to use Cookie in Java to record the last visit time of a page. Today we will talk about how to use Cookie in PHP. You can choose according to your favorite language!

                                                                                   ​​
//Cookie records whether the page is the first time Visited tag                 $flag = false;
            // First check whether there is a value for the lastVisit key in the cookie

                                                        use           use using ’s  to  ‐  ‐ ‐ ‐                                                                                                                 $ : ''; (If ($ Lastvisit) {
// setcookie () must be written before the echo statement, otherwise it will be due to http, pHP error // If you really want to put it on the Echo statement, After that, you need to enable ob cache

            setcookie('lastVisit', date('Y-m-d H:i:s', time()), time()+3600);               $flag = true; Visit time: '.$lastVisit; ()),time()+3600); echo 'This is your first time visiting this page! ';

                                                                                   Today we mentioned a concept: OB cache. This knowledge point is very important and of great practical value. I will open a special course to talk about it another day, so stay tuned! This ends the sharing. If you think it’s a good talk, please give me a reward
