Usage

PHP API

You can use the World facade to retrieve countries, states, and cities.

Retrieve Countries

use JSzD\World\Facades\World;

// Get all countries (default fields: id, name, iso2)
$countries = World::countries([])->data;

// Get countries with specific fields and search
$countries = World::countries([
    'fields' => 'id,name,iso2,phone_code',
    'search' => 'United',
])->data;

// Filter countries
$countries = World::countries([
    'filters' => [
        'iso2' => 'US'
    ]
])->data;

Retrieve States

// Get states for a country
$states = World::states([
    'filters' => [
        'country_code' => 'US'
    ]
])->data;

Retrieve Cities

// Get cities for a state
$cities = World::cities([
    'filters' => [
        'state_id' => 123
    ]
])->data;

// Get cities for a country
$cities = World::cities([
    'filters' => [
        'country_code' => 'US'
    ]
])->data;

Caching

You can chain the withCaching() method to cache the result of the query.

$countries = World::withCaching()->countries([])->data;

API Endpoints

If enabled in the configuration, the following API endpoints are available:

Query Parameters

All endpoints support the following query parameters:

• fields: Comma-separated string of fields to return (e.g., id,name).
• filters[field]: Filter by a specific field.
• search: Search by name (using LIKE %search%).

Example: GET /api/countries?fields=name,phone_code&search=Hung

Models

The package provides the following Eloquent models:

• JSzD\World\Models\Country
• JSzD\World\Models\State
• JSzD\World\Models\City

You can use these models to define relationships in your own models:

public function country()
{
    return $this->belongsTo(\JSzD\World\Models\Country::class);
}
