Answer 1

$m = 0;
array_walk_recursive($arr, function($v) use (&$m) { $m = max($m, $v); }); 

Answer 2

$arrChild = $arr["hostlist"]["hh-yun-ceph-cinder015-128055.vclound.com"]["net.if.in[bond1]"];
echo max($arrChild);

Answer 3

$arr = array(
    'hostlist' => array(
        'hh-yun-ceph-cinder015-128055.vclound.com' => array(
            'net.if.in[bond1]' => array(
                "29408880",
                "38533912",
                "38106808",
                "38263176",
                "39617752",
                "36451976"
            )
        ),
    )
);echo max($arr['hostlist']['hh-yun-ceph-cinder015-128055.vclound.com']['net.if.in[bond1]']);
