how to show 500 internal Server error page in laravel 5.2?

Title: Handling 500 Internal Server Errors in Laravel 5.2 and Preventing Syntax Mistakes

Body: When developing applications using the popular PHP framework Laravel, it's essential to handle errors effectively. In this blog post, we will focus on creating a dedicated error page for displaying 500 internal server errors (also known as Internal Server Error or HTTP status code 500) in Laravel 5.2, which can be shown when a user-introduced syntax mistake occurs in the project.

First and foremost, to implement a robust error handling mechanism, you need to create an error view template specifically for the 500 internal server error. This can be done by creating a new Blade file named "errors\50x.blade.php" inside your application's "resources\views\errors" directory. For this example, we will use a simple layout with basic information about the error:

@extends('layouts.app')

@section('content')
    <div class="container">
        <h1>500 Internal Server Error</h1>
        <p>Oops! Something went wrong.</p>
        <p>The application encountered an error and could not continue processing your request. If you believe this to be a bug, please contact the administrator of this application.</p>
    </div>
@endsection

Next, in Laravel 5.2, the default exception handler is located at "app\Exceptions\Handler.php." By overriding the "render" method within this class, you can customize how exceptions are handled:

<?php

namespace App\Exceptions;

use Exception;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
use Symfony\Component\HttpKernel\Exception\HttpException;

class Handler extends ExceptionHandler
{
    /**
     * A list of the exception types that should not be reported.
     *
     * @var array
     */
    protected $dontReport = [
        HttpException::class,
    ];

    /**
     * Report or log an exception.
     *
     * This is a placeholder you may remove and replace with your own logic.
     *
     * @param  \Throwable  $exception
     * @return void
     */
    public function report(Exception $exception)
    {
        parent::report($exception);
    }

    /**
     * Render an exception into an HTTP response.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Throwable  $exception
     * @return \Symfony\Component\HttpFoundation\Response
     */
    public function render($request, Exception $exception)
    {
        if ($exception instanceof \Illuminate\Validation\ValidationException) {
            return redirect()->back()->withInput()->withErrors($exception->errors());
        } else if ($exception instanceof \Symfony\Component\HttpKernel\Exception\HttpException) {
            $statusCode = $exception->getStatusCode();
            return response()->view('errors.http.' . $statusCode, [], $response->withStatus($statusCode));
        } else {
            return parent::render($request, $exception);
        }
    }
}

Note that we have provided specific conditions to render different error pages based on the type of exception thrown. For example, if a validation exception occurs (e.g., due to invalid user input), it will be redirected back to the previous page with relevant error messages; otherwise, any 50x HTTP status code will show the custom 500 internal server error page.

Finally, to ensure proper error handling for syntax errors in your Laravel application, you should implement a robust coding standard and testing process, including static analysis tools like PHP_CodeSniffer and Code Inspector by laravel/code-quality. Additionally, consider using error logging and monitoring tools such as Sentry or Rollbar to stay informed about potential issues and ensure a smooth user experience.

In conclusion, handling 500 internal server errors in Laravel 5.2 is crucial for providing a professional and well-maintained application. By implementing the outlined code best practices, you can effectively handle syntax mistakes and provide users with a clear error message when an issue arises.
