php取出多维数组重复的值

全部有重复，如数组：Array ( [0] => 2 [1] => 6 ) --Array ( [0] => 2 [1] => 7 ) --Array ( [0] => 2 [1] => 7 )
重复值为2。这里是每个里面都包含的，才取出它来

$arr = array(
array(
array(
"stocknotifyId" => 1,
"sku" => '13809_BL_37',
"email" => 'huang@aaa.com'
),
array(
"stocknotifyId" => 3,
"sku" => '13809_BL_37',
"email" => 'hrheve@dfwef.com'
),
array(
"stocknotifyId" => 5,
"sku" => '13809_BL_37',
"email" => 'dfsfs@dfsf.com'

array(
array(
"stocknotifyId" => 4,
"sku" => '13809_BL_39',
"email" =>'hrheve@dfwef.com'
)
)
);

$re = array();

foreach($arr as $a) {
foreach ($a as $v) {
$tmp_v = $v;
unset($tmp_v['email']);
if(isset($re[$v['email']])) {
$re[$v['email']][] = $tmp_v;
}else{
$re[$v['email']] = array($tmp_v);
