Array intersect on key in array?

Question

I have an array that has countries:

array(
\'AF\'=>\'AFGHANISTAN\',
\'AL\'=>\'ALBANIA\',
\'DZ\'=>\'ALGERIA\',
\'AS\'=>\'AMERICAN SAMOA\',
);
         


        

Answer 1

I think this will help. Here is a function key_values_intersect that will work as you expected :)

$longcodes = array(
    'AF' => 'AFGHANISTAN',
    'AL' => 'ALBANIA',
    'DZ' => 'ALGERIA',
    'AS' => 'AMERICAN SAMOA',
);

$code = array('AL', 'DZ');

function key_values_intersect($haystack, $needle)
{
    $tmp=array();
    foreach ($needle AS $key) {
        $tmp[$key] = $haystack[$key];
    }
    return $tmp;
}


print_r(key_values_intersect($longcodes,$code));
