WooCommerce: get a shipping methods by Country code - php

Question

I'm trying to get the shipping available methods by country code that giving in the request, in the above code I'm facing an issue/conflict
That the available locations can be both a country or a continent so I need to check if this country code is a part of some continent.
the problem is with the first zone I get all methods in all zones not just within the first ( the callback return ).
The second zone which has the continents/countries ( rest of the world ) I get no issues with it but as far I guess that's because its the end of the loop. ( as I have two zones for now )
add_action("rest_api_init", function () {
register_rest_route(
"test-api/v1",
"shipping-cost",
array(
'callback' => function ($req) {
$country_code = $req->get_param('country_code');
$quantity = $req->get_param('quantity');
$shipping_cost = 0;
$methodes = [];
if (class_exists('WC_Shipping_Zones')) {
$all_zones = WC_Shipping_Zones::get_zones();
if (!empty($all_zones)) {
foreach ($all_zones as $zone) {
if (!empty($zone['zone_locations'])) {
foreach ($zone['zone_locations'] as $location) {
$wc_contries = new WC_Countries();
$continent_code = $wc_contries->get_continent_code_for_country($country_code);
if ($country_code === $location->code || $continent_code === $location->code) {
if (!empty($zone['shipping_methods'])) {
$shipping_method_ctrl = new WC_REST_Shipping_Zone_Methods_Controller();
foreach ($zone['shipping_methods'] as $flat_rate) {
$shipping_method = $shipping_method_ctrl->prepare_item_for_response($flat_rate, $req);
$methodes[] = (object) $shipping_method;
}
}
}
}
}
}
}
}
return $methodes;
}
)
);
});

Here's the answer: ( adding break with the number of the array want it to be stop )
Register_rest_route(
"kefan-api/v1",
"shipping-cost",
array(
'callback' => function ($req) {
$country_code = $req->get_param('country_code');
$methodes = [];
if (class_exists('WC_Shipping_Zones')) {
$all_zones = WC_Shipping_Zones::get_zones();
if (!empty($all_zones)) {
foreach ($all_zones as $zone) {
if (!empty($zone['zone_locations'])) {
foreach ($zone['zone_locations'] as $location) {
$wc_contries = new WC_Countries();
$continent_code = $wc_contries->get_continent_code_for_country($country_code);
if ($country_code === $location->code || $continent_code === $location->code) {
if (!empty($zone['shipping_methods'])) {
$shipping_method_ctrl = new WC_REST_Shipping_Zone_Methods_Controller();
foreach ($zone['shipping_methods'] as $flat_rate) {
$shipping_method = $shipping_method_ctrl->prepare_item_for_response($flat_rate, $req);
$methodes[] = (object) $shipping_method;
}
break 2;
}
}
}
}
}
}
}
return $methodes;
}
)
);
