In Laravel, you can generate reports by using various libraries or packages such as DomPDF, Snappy, etc. You can also write custom code to generate reports. Here’s a simple example of generating a report using the DomPDF library:

Install the library using Composer:

composer require barryvdh/laravel-dompdf

Add the service provider to the providers array in the config/app.php file:

Barryvdh\DomPDF\ServiceProvider::class,

Add an alias for the PDF class to the aliases array in the config/app.php file:

'PDF' => Barryvdh\DomPDF\Facade::class,

Create a new controller method to generate the report:

use PDF;

public function generateReport()
{
    $pdf = PDF::loadView('report');
    return $pdf->download('report.pdf');
}

Create a view file report.blade.php with the HTML content for the report:

<h1>Report</h1>
<p>This is a sample report.</p>

Call the generateReport method to generate the report and download it.

You can customize this example to generate reports with different data, styles, and formats.

Pass Data

You can pass data to the blade template by adding an array as a second parameter to the loadView method:

public function generateReport()
{
    $data = [
        'title' => 'Report',
        'content' => 'This is a sample report.'
    ];

    $pdf = PDF::loadView('report', $data);
    return $pdf->download('report.pdf');
}

And in the blade template report.blade.php you can access the data as follows:

<h1>{{ $title }}</h1>
<p>{{ $content }}</p>

Stream

To show the PDF in the browser instead of downloading it, you can use the stream method instead of download:

public function showReport()
{
    $data = [
        'title' => 'Report',
        'content' => 'This is a sample report.'
    ];

    $pdf = PDF::loadView('report', $data);
    return $pdf->stream('report.pdf');
}

This will display the PDF in the browser, but still allow the user to download it if they choose to.
