<?php

/* procedural API */
$memcache_obj = memcache_connect('memcache_host', 11211);
$var = memcache_get($memcache_obj, 'some_key');

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

/* 
You also can use array of keys as a parameter.
If such item wasn't found at the server, the result
array simply will not include such key.
*/

pls aware of the get() function will change the content of your variable:



e.g.



$key = "this is a test";

$memcache->set($key, 1);



echo $memcache->get($key); // print out "1", as expected

echo $key;                          // print out "this_is_a_test"



i think you would like to use as the following:



$memcache->set("$key", 1);

echo $memcache->get("$key");
