# Memcache::getExtendedStats

(No version information available, might be only in CVS)

Memcache::getExtendedStats — Get statistics from all servers in pool

### Description

array Memcache::getExtendedStats ([ string `$type` [, int `$slabid` [, int `$limit` ]]] )

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.

> Note: This function has been added to Memcache version 2.0.0.

### 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.

### Return Values

Returns a two-dimensional associative array of server statistics or `FALSE` on failure.

### Examples

Example #1 Memcache::getExtendedStats() example

`<?php
$memcache_obj = new Memcache;
$memcache_obj->addServer('memcache_host', 11211);
$memcache_obj->addServer('failed_host', 11211);
$stats = $memcache_obj->getExtendedStats();
print_r($stats);
?>`

The above example will output:

    Array
    (
        [memcache_host:11211] => Array
            (
                [pid] => 3756
