    ],
    "psr-4": {
        "App\\": "app/",

namespace App\Http\Controllers;
use ECPaySDK;
use Illuminate\Http\Request;
use Mail;
use App\Http\Requests;
use App\Travel_user;
use App\Travel_user_place;
use App\Place;
use App\Files;
use App\House;
use DB;
use Illuminate\Support\Facades\File;
class BackendController extends Controller

sdk class

<?php
namespace ECPaySDK;
abstract class ECPay_PaymentMethod {
const ALL = 'ALL';

Solution

After adding it to composer.json, import it to your class with use keyword. Change this

namespace ECPaySDK;

To

use ECPaySDK\ECPay_AllInOne;

In the format NAMESPACE\CLASSNAME;

For this to work, go at the top of your file and define a namespace. It seems there is no namespace for now. You can define like this

namespace ECPaySDK;

So depending on the class you want to use, prefix it with ECPaySDK namespace. Assuming you put your your SDK directory at the root of your application.

Update

You have a single file with multiple class declarations. Go to your composer file in the autoload part, just below "psr-4" create a new entry called files.

"files": [
    "ECPaySDK/ECPaymentIntegration.php"
]

Then run composer dumpautoload
