How to pass the variable in blade file from controller in laravel

1. Using compact method:

The easiest way is to use the PHP compact function. In your controller function, define the variable and pass it to the view using compact. Here's an example:

public function index()
{
    $name = 'Najmul Hasan';
    return view('welcome', compact('name'));
}

In this example, we're passing $name variable to the welcome.blade.php file.

2. Using with method:

Another way to pass a variable is to use the with method on the view. Here's how:

public function index()
{
    $name = 'Najmul Hasan';
    return view('welcome')->with('name', $name);
}

In this approach, we are returning the view welcome, and using the with method along with the $name variable to pass it into the view.

3. Using array:

You can also pass multiple variables using an array. Here's an example:

public function index()
{
    $data['name'] = 'Najmul Hasan';
    $data['age'] = 30;
    return view('welcome', $data);
}

In this approach, we are returning the view welcome. We are passing an array containing two keys, name and age. These keys contain their respective value, which will be used in the welcome.blade.php file using the same name.
