Error occurs here:

$slabs[$id]['request_rate'] = @sprintf('%.1f', ($slab['get_hits'] + 
$slab['cmd_set'] + $slab['delete_hits'] + $slab['cas_hits'] + 
$slab['cas_badval'] + $slab['incr_hits'] + $slab['decr_hits']) / 
$slabs['uptime'], 1);
                $slabs[$id]['mem_wasted'] = (($slab['total_chunks'] * $slab['chunk_size']) < $slab['mem_requested']) ?(($slab['total_chunks'] -  $slab['used_chunks']) * $slab['chunk_size']):(($slab['total_chunks'] * $slab['chunk_size']) - $slab['mem_requested']);

Hello,
Does this bug produce only when your cache is empty or every time ?

Everytime

Adding this above those lines will fix it:

                if (!isset($slab['get_hits'])) $slab['get_hits'] = 0;
                if (!isset($slab['cmd_set'])) $slab['cmd_set'] = 0;
                if (!isset($slab['delete_hits'])) $slab['delete_hits'] = 0;
                if (!isset($slab['cas_hits'])) $slab['cas_hits'] = 0;
                if (!isset($slab['cas_badval'])) $slab['cas_badval'] = 0;
                if (!isset($slab['incr_hits'])) $slab['incr_hits'] = 0;
                if (!isset($slab['decr_hits'])) $slab['decr_hits'] = 0;
                if (!isset($slab['mem_requested'])) $slab['mem_requested'] = 0;

Or you can just turn notices off.

Two fixes here:

Either add error_reporting(E_ALL ^ E_NOTICE); at the top of the index.php file. 
(Bad way but it will hide the notices).

Or add the following code (solution posted above) line 246 in the 
Library/Data/Analysis.php file:

if (!isset($slab['get_hits'])) $slab['get_hits'] = 0;
if (!isset($slab['cmd_set'])) $slab['cmd_set'] = 0;
if (!isset($slab['delete_hits'])) $slab['delete_hits'] = 0;
if (!isset($slab['cas_hits'])) $slab['cas_hits'] = 0;
if (!isset($slab['cas_badval'])) $slab['cas_badval'] = 0;
if (!isset($slab['incr_hits'])) $slab['incr_hits'] = 0;
if (!isset($slab['decr_hits'])) $slab['decr_hits'] = 0;
if (!isset($slab['mem_requested'])) $slab['mem_requested'] = 0;

Hmm, I didn't have any of those problems with php7. Is this a resolved bug? (I haven't tried phpmemcachedadmin with php5 but php 5.3 is EOL.

Similar issue with PMCA 1.3.0 and Memcache 1.5.17 to 1.5.19:

mem_requested moved from slab stats to item stats, as per https://github.com/memcached/memcached/wiki/ReleaseNotes1517

So in Analysis::slabs(), one needs to fetch either $slab['mem_requested'] for earlier versions, or $slab['items:mem_requested'] for newer versions.
