Summary of several methods of PHP clear cache

Now the development of the project is using tp3.1 version, in the development process we often encounter the problem of page cache (especially the HTML cache), after the refresh or the old version of the number, and then refresh the old version of the data, slowly began to doubt life, haha; so in the development process we need to clear the cache every time.

There are about 3 ways to clear the cache (both are actual experience summaries):

First: You can avoid caching problems by adding the following two lines of code to the project's configuration file config.php

' tmpl_cache_on ' + false,//prohibit template compilation cache  ' html_cache_on ' = false,//disable static caching

These two lines of code here I do not explain;

Second: The TP framework cache directory is stored in the folder Public_html\app\runtime, after each development is completed manually delete all the files inside
(feeling a bit violent and stupid), but this method is the stupidest, testing and online environment if you do not have permission to delete;

Third: I write to clear the cache class, we can in the business controller in the same directory to create their own "clear cache" class (the core idea is to use the TP framework with the cache class to operate, TP framework of the source code you can see), through the way of URL access to clear cache,

The code is as follows:

Trim ( $_get[' token ']): '; $_operate = isset ($_get[' operate ')?  Trim ($_get[' operate '): "; $_option = Array (); if ($_operate = = ' runtime ') $_option[' temp '] = Runtime_path; Various cache data holds directory if ($_operate = = ' cache ') $_option[' temp ' = Cache_path; if ($_operate = = ' data ') $_option[' temp '] = Data_path; if ($_operate = = ' Fields ') $_option[' temp '] = Data_path. "  /_fields "; Import (' Think.Util.Cache.CacheFile '); $CacheFile = new Cachefile ($_option); $CacheFile->clear (); echo ' success '; }

The clear function is actually deleting the cache file.
