<p><strong>What is Laravel?</strong></p>
<p>Laravel is an open-source PHP web framework that is free of cost to use. It was designed and developed to create various web applications based on Symphony.&nbsp;</p>
<p><strong>What is Middleware?</strong></p>
<p>In the <a href="https://www.bestinterviewquestion.com/laravel-interview-questions"><strong>Laravel interview questions</strong></a>, it is regularly requested that what the correlation between the two is? The reply to this query is - The Middleware, as you know, is software, which is a connecting platform between the working device and the purposes that are walking on that interface. The functioning of the Middleware is a platform that features on the equal working standards as that of the &ldquo;if and else loop.&rdquo; &nbsp;</p>
<ul>
    <li><strong>Global Middleware&nbsp;</strong>&ndash; Runs on each HTTP related issue. If you want to run Middleware on all the requests, then choose this one.</li>
    <li><strong>Route Middleware</strong> &ndash; Runs on a particular HTTP pertaining issue.</li>
</ul>
<p><strong>Importance of Middleware in Laravel Filtering HTTP requests &ndash;&nbsp;</strong></p>
<ol>
    <li>V<strong>erifying user authentication&nbsp;</strong>&ndash;Various functions that run on the codes processed through Laravel can&#39;t enable each person to get entry to and use the platform it provides. For this very purpose, Laravel requires Middleware to determine and procedure whether or not a unique Laravel platform gets entry to request is actual or not.&nbsp;</li>
    <li><strong>Processing HTTP access</strong> - Middleware renders a platform to provide a convenient mechanism for handling HTTP requests present in your application.&nbsp;</li>
    <li><strong>A link between the user request and the access</strong> &ndash; Laravel requires some platform to act as a connecting platform between its programming software and applications as well the users who want to access those.&nbsp;</li>
</ol>
<p><strong>Example</strong></p>
<ul>
    <li>To verify the authentication user, Laravel includes Middleware.</li>
    <li>If the Middleware finds the consumer login as authenticated, then it will, in addition, raise ahead with the request to proceed to use the application.</li>
    <li>If the Middleware finds the person login as unauthenticated, then it will decline the user&rsquo;s request and redirect them to the domestic screen.</li>
</ul>
<p>Just appear at a regular code to be run through middleware to determine whether or not to enable the person to get right of entry to to the platform or not.&nbsp;</p>
<p>namespace App\Http\Middleware;</p>
<p><br></p>
<p>use Closure;</p>
<p><br></p>
<p>class Before Middleware</p>
<p>{</p>
<p>&nbsp; &nbsp; public function handle($request, Closure $next)</p>
<p>&nbsp; &nbsp; {</p>
<p>&nbsp; &nbsp; &nbsp; &nbsp; // You can write here your condition</p>
<p><br></p>
<p>&nbsp; &nbsp; &nbsp; &nbsp; return $next($request);</p>
<p>&nbsp; &nbsp; }</p>
<p>}</p>
