如何使用Memcache加速PHP？

Question

I have enabled the memcache extension for my PHP Apache localserver server (XAMPP)

but I don't know how to use it to speed up my PHP scripts Is writing the following code in the top of every page I want to speed up is enough? or I should do something else?

       /* procedural API */
       $memcache_obj = memcache_connect('127.0.0.1', 11211);

       /* OO API */
       $memcache = new Memcache;
       $memcache->connect('127.0.0.1', 11211);

the phpinfo() shows the following details

        memcache support    enabled
        Active persistent connections   0
        Version 2.2.4-dev
        Revision    $Revision: 1.99 $

Thanks

You might want to consider using memcache_pconnect() instead but there are pros and cons to that.

You've got memcache setup. It won't speed up anything unless you use it for something. There are four basic things you can cache:

1. Loading stuff from a file;
2. Loading stuff from a database;
3. Loading stuff from a remote host; and
4. Storing the result of something that takes significant time to calculate.

Until you use it for something, it won't do anything.
