Use array_slice:

$input_array = array('a'=>'a', 'b'=>'b', 'c'=>'c', 'd', 'e');
$first_two =  array_slice($input_array, 0, 2, true);

From your code it looks like you actually want the key and the value...

<select name="country">
<?php
foreach($countryArray as $code=>$country){
echo "<option value=".$code.">".$country."</option>";
}
</select

You could use array_slice

$arrays = [
        "" => "Select country",
        "AF" => "Afghanistan",
        "DZ" => "Algerian",
        "AO" => "Angola"
    ];

$first = array_slice($arrays, 0, 1);
$second = array_slice($arrays, 1, 1);
$first_two = array_slice($arrays, 0, 2, true);   
$first_three = array_slice($arrays, 0, 3, true);
