How to use memcache with php

I am new to this memcache stuff. I read that it saves lot of time of page load time by caching the database key. I have my php application and I want to use memcache as it takes too much time for my application to retrieve the whole set of results from databas开发者_如何转开发e.

Steps to take: Prerequisite: read the manual (at least a bit): http://php.net/manual/en/book.memcache.php and make sure you've got memcached installed.

1 Start the memcached program so there is a server that actually stores the key-value pairs.

2 Make a memcache object

3 Store a value for a key

4 Retrieve your key.

$memcache = new Memcache; //point 2. 
$memcache->set($yourUniqueKey,  $yourValue, false, 3600); //point 3
//later:
$memcache->get($yourUniqueKey); //point 4.
