答复: Tag Function

[Robert Q. Liu]

Hi,

One tag can be set for one or more keys, and one key can have one or more tags.

For example: 
    $memcache->tag_add("tag_1", array("key1", "key2", "key3", "key4"));
    $memcache->tag_add("tag_2", "key1");

tag_1 and tag_2 both have key1.
set tag_1 to key1, key2, key3, key4 at once.

Welcome discussion. Thank you!

主题: Re: Tag Function

can some key have multiple tags ? 
can I set tag for more than one key at once ? 

It looks promising,  I will made afuture investigations, but it seems to cover  my needs. for simple  multidimensional storage and droping row or column....
