Laravel String Helpers: 16 Open-Source Examples

Laravel has a lot of valuable helper functions. This post will show 16 examples of string helpers and how they are used in real projects.

Notice: String Syntax Changes

Before we begin, a little notice: you may find different variants of the same String functions, so you would understand the differences, here's what were added in Laravel lately.

• In Laravel 7, they added Fluent String Operations. You may create a fluent Illuminate\Support\Stringable object using the Str::of() method. All fluent string methods can be found in the official documentation.
• In Laravel 9, they added a new str() helper. The str() function is shorter and equivalent to the Str::of() method, which returns the Illuminate\Support\Stringable.

1. Str::slug()

The easiest way to create a slug from a given string without using any external packages is the Str::slug() helper.

An example is from an open-source platform BookStackApp.

use Illuminate\Support\Str;
 
class ImageStorage
{
    // ...
 
    public function cleanImageFileName(string $name): string
    {
        $name = str_replace(' ', '-', $name);
        $nameParts = explode('.', $name);
        $extension = array_pop($nameParts);
        $name = implode('-', $nameParts);
        $name = Str::slug($name); 
 
        if (strlen($name) === 0) {
            $name = Str::random(10);
        }
 
        return $name . '.' . $extension;
    }
 
    // ...
}

2. Str::title()

Create a title from a string where the first letter of every word starts with a capital letter using Str::title() helper.

An example is from an open-source platform BookStackApp.

// ...
<h1 class="list-heading">{{ Str::title(trans('auth.log_in')) }}</h1>
// ...

3. Str::startsWith()

If you need to check whether a string starts with a given value, the Str::startsWith() helper is just for that.

An example is from an open-source project Pterodactyl.

use Illuminate\Support\Str;
 
class ActivityLogged extends Event
{
    // ...
 
    public function isServerEvent(): bool
    {
        return Str::startsWith($this->model->event, 'server:');
    }
 
    // ...
}

4. Str::endsWith()

Opposite to the Str::startsWith(), the Str::endsWith() helper checks if a given string end with a provided value.

An example is from an open-source project creater.

use Illuminate\Support\Str;
 
class PathToZip implements Rule
{
    // ...
 
    public function passes($attribute, $value)
    {
        return Str::endsWith($value, '.zip');
    }
 
    // ...
}

5. Str::before() and basename()

The Str::before() helper returns everything from a string before a given value.

An example is from...
