How to Fetch Currency Exchange Rates in Laravel?

Hello Friends,

Now, let's see an example of how to fetch currency exchange rates in laravel. it's a simple example of getting current and historical currency exchange rates in laravel. I explained simply step by step how to get currency exchange rates in laravel. you will learn how to convert one currency to another using laravel currency.

Laravel Currency is a Laravel package that gives the historical, latest currency rate and converts from one currency to another. It also provides crypto exchange rates. This is possible with the help of the exchange rate.host API which is free and does not need an API key.

You can use this example with laravel 6, laravel 7, laravel 8, and laravel 9 versions.

You have just to follow the below step and you will get the layout as below:

Step 1: Install Laravel


This is optional; however, if you have not created the laravel app, then you may go ahead and execute the below command:

composer create-project laravel/laravel example-app

Step 2: Integrating the currency library

To install the package, we run the command below.

composer require amrshawky/laravel-currency

Step 3: Converting currency

In the code below, we convert One Currency to Other Currency

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use AmrShawky\LaravelCurrency\Facade\Currency;

class DemoController extends Controller

{

/**

* Display a listing of the resource.

*

* @return \Illuminate\Http\Response

*/

public function index(Request $request)

{

$converted = '';

if($request->filled("currency_from")){

$convertedObj = Currency::convert()

->from($request->get('currency_from'))

->to($request->get('currency_to'))

->amount($request->get('amount'));

if($request->filled('date')){

$convertedObj = $convertedObj->date($request->get('date'));

}

$converted = $convertedObj->get();

}

return view('currency',compact('converted'));

}

}

Step 4: Create Currency Route

web.php

<?php

use Illuminate\Support\Facades\Route;

use App\Http\Controllers\DemoController;

/*

|--------------------------------------------------------------------------

| Web Routes

|--------------------------------------------------------------------------

|

| Here is where you can register web routes for your application. These

| routes are loaded by the RouteServiceProvider within a group which

| contains the "web" middleware group. Now create something great!

|

*/

Route::get('/', function () {

return view('welcome');

});

Route::get('/currency',[DemoController::class,'index'])->name('currency');

Step 5: Create Currency Index View

let's create Currency.blade.php(resources/views/currency.blade.php) for the form and we will write the design code here and put the following code:

currency.blade.php

<!DOCTYPE html>

<html>

<head>

<meta charset="utf-8">

<meta name="viewport" content="width=device-width, initial-scale=1">

<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-EVSTQN3/azprG1Anm3QDgpJLIm9Nao0Yz1ztcQTwFspd3yD65VohhpuuCOmLASjC" crossorigin="anonymous">
