3. apc usage example APC is very simple to use. See the following examples of adding, querying, modifying, and deleting. 1), add a cache, the effective time is 3600 seconds apc_add('name', 'tom', 3600); Execute the code, and then check the User Cache Entries. You can see that there is an additional cache data with the key value name: Among them are the number of hits, size, expiration time, etc. 2) Query cache

apc_add('name', 'tom', 3600);
print apc_fetch('name'); //Output tom

3), modify cache

apc_store('name', 'anny', 3600);
print apc_fetch('name'); //Output anny

4), delete cache

apc_delete('name');
var_dump(apc_fetch('name')); //Output bool(false)

5), increasing and decreasing numbers If the cached content is a number, you can use apc_ inc to increase by 1 and apc_dec to decrease by 1.

apc_add('num', 10);
apc_inc('num');
print apc_fetch('num');//Output 11
apc_dec('num');
print apc_fetch('num ');//Output 10

6), determine whether the cache exists

apc_add('name', 'tom', 3600);
var_dump(apc_exists('name')); //Output bool(true)
var_dump(apc_exists('age')); // bool(false)
