In this tutorial, you’ll learn how to convert a string to uppercase in Laravel using both a controller method and a Blade template.

Part 1: Converting String to Uppercase in Laravel Controller

Step1: Create a New Controller

  1. Open your Laravel project’s terminal.
  2. Use the php artisan make:controller command to create a new controller. For instance, create an “UppercaseController”:
php artisan make:controller UppercaseController

Step2: Implement Uppercase Conversion

  1. Open the newly created UppercaseController.php file in the app/Http/Controllers directory.
  2. In a controller method, use the Str::upper() function to convert a string to uppercase:
use Illuminate\Support\Str;

// ...

public function toUppercase($inputString)
{
    $uppercaseString = Str::upper($inputString);
    return view('uppercase', ['inputString' => $inputString, 'uppercaseString' => $uppercaseString]);
}

Step3: Define Route

  1. Open the routes/web.php file.
  2. Define a route that uses the toUppercase method in the UppercaseController:
Route::get('/uppercase/{input}', 'UppercaseController@toUppercase');

Part 2: Displaying Uppercase String in Laravel Blade Template

Step1: Create a Blade View

  1. Navigate to your Laravel project’s resources/views directory.
  2. Create a new Blade view file. For instance, name it “uppercase.blade.php”.

Step2: Display Uppercase String in Blade Template

  1. Open the “uppercase.blade.php” file.
  2. Inside the Blade template, display the uppercase string passed from the controller:
<!DOCTYPE html>
<html>
<head>
    <title>String to Uppercase Conversion</title>
</head>
<body>
    <p>Uppercase String Controller: {{ $uppercaseString}}</p>
    <p>Uppercase String Blade: {{ Str::upper($inputString) }}</p>
</body>
</html>
