PHP Development APP Interface Summary-static cache

Storing a static cache writes the cache to a file.

file.php

<?PHPclasscache{//static cache file suffix name    ConstEXT = ' txt '; //defining cache file Storage Paths    Private $_dir;  Public function__construct () {$this->_dir =dirname(__file__).‘ /files/'; }     Public functionCacheData ($k,$v= ",$path= ' '){        //file name        $filename=$this->_dir.$path.$k.‘.‘.

======

Modify it slightly, set the cache for n minutes, regenerate the cache for more than n minutes, or read the data from the cache.

In file.php, file name and file modification time are also stored in cached data when storing data.
