Php implements the method of caching class code: [$cache = new Cache (); $values = $cache- > get ($key); if ($values = = false) {$cache- > put ($key, $values).]

This article operating environment: windows10 system, php 7, thinkpad T480 computer.

Instructions for use:

1. Instantiation

$cache = new Cache ()

2. Set cache time and cache directory

$cache = new Cache (60,'/ any_other_path/')

The first parameter is the number of seconds to cache, and the second parameter is the cache path, which is configured as needed.

By default, the cache time is 3600 seconds and the cache directory is cache/

3. Read cache

$value = $cache- > get ('data_key')

4. Write cache

$value = $cache- > put ('data_key',' data_value')

Complete example:

$cache = new Cache (); / / data reading key value $key from cache $values = $cache- > get ($key); / / if there is no cached data if ($values = = false) {/ / insert code here...// writes data with key value $key $cache- > put ($key, $values);} else {/ / insert code here...}
