The php file cache class extracted from the CI community's stblog and CI's file_helper class, a simple file-based key->value cache class. This class can be used to cache some basic information, such as some infrequent changes in the header, footer, and sidebar of the blog, and the content taken out from the database. Before fetching the data, first determine whether the content in the file cache has expired. If it has not expired, take it out. , if it expires, connect to the database to query, rewrite the results into the file cache, and update the expiration time.

First download the php cache file class extracted from CI that we need to use in this course: http://www.php.cn/xiazai /leiku/478

After the download is complete, find the php class file we need, unzip it to our local directory, and create a new php file!

After completion, we need to call this class in the new php file and instantiate the class:

<?php

include_once "cache1.php";//引入类文件
$cache = new FileCache(30,&#39;cache/&#39;); //实例化
$cache->set(&#39;test&#39;,&#39;php中文网:www.php.cn&#39;);
print $cache->get(&#39;test&#39;);
?>

The running result is as shown below:

How do you loop through all the values stored in a PHP session?How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.
