user id 16 & 17 don't have two value that you want (english,word) ! They have only one value in each id — Jack jdeoel, Aug 09 '17 at 07:04
StackOverflow is not a tutorial site nor search engine replacement. We can help, but it's your job to work on this in first place. [Put some efforts](http://meta.stackoverflow.com/questions/261592) first, then ask with a clear explanation and [MCV example](http://stackoverflow.com/help/mcve) if applicable. — Milan Chheda, Aug 09 '17 at 07:05
@ShahinA.M, change your description to *to search the user_ids that have two value : english **OR** word* — RomanPerekhrest, Aug 09 '17 at 07:08

The solution using array_intersect function:

$arr = [ 17 => ["word", "power point", "excel"], 16 => ["english", "french", "farsi"] ];
$search_keys = ["english", "word"];
$keys = [];

foreach ($arr as $k => $v) {
    if (array_intersect($search_keys, $v)) $keys[] = $k;
}

print_r($keys);

The output:

Array
(
    [0] => 17
    [1] => 16
)
