Description:
------------
In PHP Version 5.3.2-1ubuntu4.5, php-memcache version 3.0.4-
2build1
When setting an integer value using memcache::set I can 
retrieve it without a problem by connecting to 
localhost:11211 and issuing a GET command. However, 
memcache::get will always return false when outputting the 
value of that variable.
The same also happens with floats (such as 0.5)

Reproduce code:
---------------
Example PHP code
<?php
	$memcache_obj = new Memcache();
	$memcache_obj -> connect ('localhost',11211);
	$memcache_obj -> set ("my_var", 5, MEMCACHE_COMPRESSED, 0);
	var_dump ($memcache_obj -> get ("my_var")); //will always output bool(false)
?>
However, using netcat:
errietta@Mewtwo:~$ nc localhost 11211
get my_var
VALUE my_var 770 1
5
END



Expected result:
----------------
I was expecting my_var to be an int(5)

Actual result:
--------------
bool (false) was outputted.
