[tp framework cache usage]

Cache variable information (ordinary variables, arrays, objects),
Cache static html content, cache part or all

Most of our data is obtained from the mysql database.

Cache media: memory (memcache), file (processing database), cache to database

The data is stored in the database after optimization.

Tp framework’s file cache (shortcut function):
a) Set S (name, value)
b) Read S (name)
c) Delete S (name, null)

1 You can set cache files to different directories to store

This can avoid storing too many cache files in one directory and affecting performance

　2 Cache validity period

S(name, value, time);

　3 Cache settings

　4 Cache usage:

　5 Cache deletion

　6 Caching use cases

【System Variables】

Use all variables in the template $_GET $_POST $_SESSION $_COOKIE, etc.
Constant usage:
$Think.const.Constant name
$Think.get.Name

Get the configuration variable information config.php in the template
$Think.config.name

Get configuration variable information in the controller
C (name); //Shortcut function
