How to modify ThinkPHP cache to Memcache_PHP tutorial

Generally speaking, ThinkPHP's default caching method is implemented in File file mode, and many cache files will be generated under /Runtime/Temp during runtime.
In some cases, after memcached is installed on the server, it is necessary to change ThinkPHP's caching method to memecache
The specific steps are as follows:

Add in Conf/config.php:

'DATA_CACHE_TYPE' => 'Memcache', 
'MEMCACHE_HOST'  => 'tcp://127.0.0.1:11211', 

After updating the cache, I refreshed the page and found that the cache did not take effect.
Get debugging information:

[ 2010-09-30T11:41:56+08:00 ] NOTIC: [8] MemcachePool::set(): Server 127.0.0.1 (tcp 11211, udp 0) failed with: CLIENT_ERROR bad command line format (0) CacheMemcache.class.php 第 107 行. 

So I found this sentence:

return $this->handler->set($name, $value, 0, $expire); 

After further debugging, it was found that the value of $expire is -1; the cache duration was not specified when writing the program, and the -1 here may not be accepted by memcached.
So add in Conf/config.php:

'DATA_CACHE_TIME' => '3600',

Specify the default cache duration as 3600 seconds; run it again, the error disappears, and the cache is successful!

In addition, when you need to clear all caches in a certain action, you can do this:

$cache = Cache::getInstance(); 
$cache ->clear();
