In this tutorial, you’ll learn how to replace a specific string with another in Laravel, utilizing a controller method and implementing the change directly in a Blade template.

Part 1: String Replacement in Laravel Controllers

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 example, create a “StringReplaceController”:
    php artisan make:controller StringReplaceController
    

    Step2: Implement String Replacement

    1. Open the newly created StringReplaceController.php file in the app/Http/Controllers directory.
    2. In a controller method, use the str_replace() function to replace a specific string with another:
    public function replaceString($originalText)
    {
        $replacementText = str_replace('old_string', 'new_string', $originalText);
        return view('string-replace', ['originalText' => $originalText, 'replacementText' => $replacementText]);
    }
    

    Step3: Define Route

    1. Open the routes/web.php file.
    2. Define a route that uses the replaceString method in the StringReplaceController:
    Route::get('/string-replace/{text}', 'StringReplaceController@replaceString');
    

    Part 2: String Replacement in Blade Templates

    Step1: Create a Blade View

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

    Step2: Perform String Replacement in Blade Template

    1. Open the “string-replace.blade.php” file.
    2. Inside the Blade template, use the str_replace() function to perform the string replacement:
    <!DOCTYPE html>
    <html>
    <head>
        <title>String Replacement Example</title>
    </head>
    <body>
        <p>Original Text: {{ $originalText }}</p>
        <p>Replaced Text: {{ str_replace('old_string', 'new_string', $replacementText) }}</p>
    </body>
    </html>
    

    Conclusion

    You’ve successfully learned how to replace a specific string with another using both a Laravel controller method and directly within a Blade template. This approach provides flexibility in how you implement string replacement in your Laravel application.
