Cookies record the path of a user's browsing product

In the e-commerce Web site, the user's browsing path is often recorded to determine which items the user is interested in, or which products are related.

The following will use cookies to record the user's browsing history page. The site stores the title of each page in the $title variable for that page, adding the newly visited title to the COOKIE variable $_cookie["History" value each time the user accesses it.

As the number of pages visited increases, the string that is stored in the cookie variable that contains the page title is getting longer. Cut the cookie variable into an array. Then output the value of the array element to output the title of the page that the user recently visited.
