Laravel 8 Tutorial - Fluent Strings

In this video, we will learn about Fluent Strings in Laravel. Fluent strings provide a more fluent, object-oriented interface for working with string values, allowing you to chain multiple string operations together using a more readable syntax compared to traditional string operations.

There are many Fluent Strings operations. I will show you some of them. First, let's create a new controller:

php artisan make:controller TestController.

Now, go to the TestController and create a function:

public function index() 
{ 
    echo '<h1> Fluent Strings</h1>'; 
}

Create a route:

Route::get('test',[TestController::class ,'index']);

Now, let's see some of the Fluent Strings operations. Start with the after method:

The after method returns everything after the given value in a string. For example:

$slice = Str::of('Welcome to my YouTube Channel')->after('Welcome to'); 
echo $slice; 

This after method returns everything after "Welcome to". So, it will return "my YouTube Channel". Let's check:

Go to the browser and add "/test" to the URL and press enter. You can see "my YouTube Channel" here.

Now, let's see the afterLast method:

The afterLast method returns everything after the last occurrence of the given value in a string.

$slice = Str::of('App\Http\Controllers\Controller')->afterLast('\\'); 
echo $slice;

Here, in this string, there are 3 slashes. So, the afterLast method just returns this string because this is the last slash.

Let's check. Just refresh the page. You can see it's showing only "controller" ok.

Next method is append:

The append method appends the given values to the string:

$string = Str::of('Hello')->append(' Wolrd'); 
echo $string; 

This append method just appends these two strings "Hello" and "World" ok.

Let's check. Just refresh the page. You can see here the string "World" is appended with "Hello".

Now, let's see the lower method:

The lower method converts the given string to lowercase:

$result = Str::of('LARAVEL')->lower(); 
echo $result;

Also, import Str on top as follows:

use Illuminate\Support\Str; 

Let's check. You can see here the string is in lowercase.

Next method is Replace:

The replace method replaces a given string within the string:

$replaced = Str::of('Laravel 7.x')->replace('7.x', '8.x'); 
echo $replaced; 

You can see here "7.x" replaced with "8.x".

Next method is title:

The title method converts the given string to Title Case:

$converted = Str::of('this is a title')->title(); 
echo $converted; 

You can see here the string is now in title case.

Now, let's see the Slug method:

The slug method generates a URL-friendly "slug" from the given string:

$slug = Str::of('Laravel Framework')->slug('-'); 
echo $slug;

You can see now this is a slug ok.

Next method is substr:

The substr method returns the portion of the string specified by the given start and length parameters:

$string = Str::of('Laravel Framework')->substr(8); 
echo $string;
$string = Str::of('Laravel Framework')->substr(8, 5); 
echo $string;

You can see "Framework" and "Frame".

Next method is trim:

The trim method trims the given string:

$string = Str::of('/Laravel/')->trim('/');
echo $string;

You can see the result here.

Now, let's see the upper method:

The upper method converts the given string to uppercase:

$adjusted = Str::of('laravel')->upper(); 
echo $adjusted;

You can see here the "Laravel" text in uppercase ok.

In this way, you can use Fluent strings in Laravel 8.
