Memcache::getExtendedStats returns a two-dimensional
associative array with server statistics. Array keys correspond to
host:port of server and values contain the individual server statistics.
A failed server will have its corresponding entry set to &false;.
You can also use the memcache_get_extended_stats function.
This function has been added to Memcache version 2.0.0.
&reftitle.parameters;
type
The type of statistics to fetch. Valid values are {reset,
malloc, maps, cachedump, slabs, items, sizes}. According to
the memcached protocol spec these additional arguments "are
subject to change for the convenience of memcache developers".
slabid
Used in conjunction with type set to
cachedump to identify the slab to dump from. The cachedump
command ties up the server and is strictly to be used for
debugging purposes.
limit
Used in conjunction with type set to
cachedump to limit the number of entries to dump. Default value
is 100.
&reftitle.returnvalues;
Returns a two-dimensional associative array of server statistics or &false;
on failure.
