PHP connection Memcache program code

Memcache is a high-performance distributed memory object cache system commonly used in php. we can use it to improve website performance and reduce server load, the following is my learning notebook. let's take a look at the simplest connection method.

Memcache is a high-performance distributed memory object cache system commonly used in php. we can use it to improve website performance and reduce server load, the following is my learning notebook. let's take a look at the simplest connection method.

The sample code is as follows:

2. $ Mem = new Memcache;
3. $ Mem-> connect ('127. 0.0.1 ', 127) or die ("cocould not connect ");
4. $ Mem-> set ('key', 'This is a test! ', 0, 60 );
5. $ Val = $ mem-> get ('key ');
6. Echo $ val;
7. ?>

The application will create a class, the code is as follows:

1. Class MCache
2. {
3.  
4. Private static $ server = array ('2017. 0.0.1 ', 127 );
5. Private static $ client = 'memcached'; // memcache or memcached
6.  
7. Private static function get_memcache ()
8. {
9. Static $ memcache;
10. If (! Is_object ($ memcache ))
11. {Www.111cn.net
12. $ Memcache = self: $ client = 'memcached '? New Memcached (): new Memcache;
13. $ Memcache-> addServer (self: $ server [0], self: $ server [1]);
14. }
15. Return $ memcache;
16. }
17.  
18. Public static function set ($ key, $ value, $ expire = 600)
19. {
20. Self: $ client === 'memcached '? Self: get_memcache ()-> set ($ key, $ value, $ expire)
21. : Self: get_memcache ()-> set ($ key, $ value, MEMCACHE_COMPRESSED, $ expire );
22. }
23.  
24. Public static function get ($ key)
25. {
26. Return self: get_memcache ()-> get ($ key );
27. }
28.  
29. }
30. MCache: set ('test _ one', 'value _ one', 60); #60 Sec
31. Print_r (MCache: get ('test _ one '));
