      ),
    \'whatever\' =>

Answer 1

array_filter() is what you need:

count(array_filter($example, function($element){

    return $element['something'] == 'other';

}));

In case you want to be more flexible:

$key = 'something';
$value = 'other';

$c = count(array_filter($example, function($element) use($key, $value){

    return $element[$key] == $value;

}));
