remove items from array with array_filter or array_walk

Question

I usually use foreach loop to remove some items from array.

foreach($array as $key=>$item){
    if($item == 'something'){
        unset($array[$key]);
    }
}

Is this possible to remove items via array_walk or array_filter?

$newarray = array_filter($array, function($var) {
    return ($var != 'something');
});

With the advent of PHP 5.6.0, it's also possible to filter by key with $newarray = array_filter($array, function($key) { return preg_match('/something/', $key); }, ARRAY_FILTER_USE_KEY); or function($value, $key) with the ARRAY_FILTER_USE_BOTH flag if the condition is looking at both key and value.
