This article mainly introduces the method of using memcached cache data in thinkphp framework, analyzes the setting and use of memcached cache in thinkphp framework, and the need of friends can refer to the following The examples in this article describe how to use memcached to cache data in the thinkphp framework. Share to everyone for your reference, as follows: thinkphp default to use the file cache data, support memcache and other caching methods, there are two PHP extensions: Memcache and

This time to bring you the thinkphp framework in the use of memcached cache data steps in detail, thinkphp framework of the use of memcached cache data considerations are what, the following is the actual case, take a look. thinkphp default to use the file cache data, support memcache and other caching methods, there are two PHP extensions: Memcache and Memcached,memcahe The official note, mainly about memcached. Relative to PHP memcache,php memcached is based on the native C libmemcached exten

Please refer to the usage of setcookie if I want to keep COOKIES permanently How can I use setcookie to implement a large value for expire? In addition, if you want to save for one month, it will be 60*60*24*30 in 30 days. Is there any precise calculation method? Reply to discussion (solution) The cookie cannot be permanently saved.What do you mean by the exact method? I meanWhen those program settings are saved for one month on the InternetJust ro

addition to the above method, we can also modify the PHP configuration file to operate the Continue the session in PHP, in PHP, mainly by setting Session.gc_maxlifetime to set the session life cycle. For example: The code is as follows Copy Code Ini_set (' Session.gc_maxlifetime ', 3600); Set timeIni_get (' session.gc_maxlifetime ')//Get the Set value in INI?> Here's a function that someone else encapsulates, but I haven't tested it for reference only:

In php, cookies are no different from other programs. Cookies are used to store information to the client. They are often used in applications with low security requirements, such as logging on to users and remembering passwords, next I will introduce the php cookie study notes. The PHP setcookie () function sends an HTTP cookie to the client. Cookie is a variable sent from the server to the browser. Cookies are usually small text files embedded into users' computers by servers. This cookie is s

What happens if I don't set an expiration time for a cookie?A Expire immediatelyB Never expireC Cookies cannot be setD Expires at the end of a browser sessionE.
