namespace App\Http\Controllers;

use Illuminate\Http\Request;

class PaypalController extends Controller
{
    public function index(Request $request)
    {
    	return view('paypal-payment-form');
    }

    public function payment(Request $request)
    {
        $request_params = array (
          	'METHOD' => 'DoDirectPayment',
          	'USER' => 'laracode101_api1.gmail.com',
          	'PWD' => 'BQJBSMHVP8WCEETS',
          	'SIGNATURE' => 'AyVuUcpetZUWCXV.EHq.qRhxEb6.AChQnxfoM9w6UJXXRBh2cH1GUawh',
          	'VERSION' => '85.0',
          	'PAYMENTACTION' => 'Sale',
          	'IPADDRESS' => '127.0.0.1',
          	'CREDITCARDTYPE' => 'Visa',
          	'ACCT' => '4032032452071167',
          	'EXPDATE' => '072023',
          	'CVV2' => '123',
          	'FIRSTNAME' => 'Yang',
          	'LASTNAME' => 'Ling',
          	'STREET' => '1 Main St',
          	'CITY' => 'San Jose',
          	'STATE' => 'CA',
          	'COUNTRYCODE' => 'US',
          	'ZIP' => '95131',
          	'AMT' => '100.00',
          	'CURRENCYCODE' => 'USD',
          	'DESC' => 'Testing Payments Pro'
       );     
     
       $nvp_string = '';     
       foreach($request_params as $var=>$val)
       {
          $nvp_string .= '&'.$var.'='.urlencode($val);
       }
     
       	$curl = curl_init();     
       	curl_setopt($curl, CURLOPT_VERBOSE, 0);     
       	curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);     
       	curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, FALSE);     
       	curl_setopt($curl, CURLOPT_TIMEOUT, 30);     
       	curl_setopt($curl, CURLOPT_URL, 'https://api-3t.sandbox.paypal.com/nvp');     
       	curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);     
       	curl_setopt($curl, CURLOPT_POSTFIELDS, $nvp_string); 

       	$result = curl_exec($curl);     
       	curl_close($curl);   

       	$data = $this->NVPToArray($result);

       	if($data['ACK'] == 'Success') {
       		# Database integration...
       		echo "Your payment was processed success.";
       	} if ($data['ACK'] == 'Failure') {
       		# Database integration...
       		echo "Your payment was declined/fail.";
       	} else {
       		echo "Something went wront please try again letter.";
       	}
    }

    public function  NVPToArray($NVPString)
    {
       $proArray = array();
       while(strlen($NVPString)) {
            // key
            $keypos= strpos($NVPString,'=');
            $keyval = substr($NVPString,0,$keypos);
            //value
            $valuepos = strpos($NVPString,'&') ? strpos($NVPString,'&'): strlen($NVPString);
            $valval = substr($NVPString,$keypos+1,$valuepos-$keypos-1);

            $proArray[$keyval] = urldecode($valval);
            $NVPString = substr($NVPString,$valuepos+1,strlen($NVPString));
        }
        return $proArray;
    }
}

Here you can check following try response we will got from the paypal REST API server.

Step - 3 Create blade file

After done controller file then we create one laravel blade HTML file which simple card payment design. Now we are create one simple blade file in resources/views/paypal-payment-form.blade.php file and here we are make very simple html layout for make card payment.

After done this step then your card payment layout look something like, please seen following sceenshot

@extends('layouts.app')

@section('content')
<div class="container">
    <div class="row justify-content-center">
        <div class="col-md-4">
            <div class="card">
