It becomes a bit tricky there in your case..
Lets say you make such wrapper (its fully possible code-wise to alter
set/get functionality (there is the open source pecl extension and also
using sockets http://code.sixapart.com/svn/memcached/trunk/api/php/ )). You
cant really fetch from memcached 'var' expecting it to be the whole array
unleast your_func_get() does know all of the array indexes (and does
multiple/batch fetching) there is no way Memcached can return anything :)
If you really like to operate with arrays pass the keys as array:
$var = memcached_get(array('x','key1','key2','key3')); will make you an
associative array where you will have $var['x'] => 'some val' $var['key1']
That's why at this point storing php arrays in some custom way I see a bit
In my opinion the thumb up rule is to store and fetch data in smaller
chunks - you always know what key/object you should get. And in case you
need to fetch/change only one element of an array the overhead getting the
whole data and puting it back wont be that serious.
