Working with files and collecting their characteristics is a regular activity for a Laravel developer in web application development.

In this tutorial, we are going to guide you through the process of calculating the file size from a file path in Laravel 10. Knowing how to retrieve file sizes is vital whether you need to display file sizes to users, do calculations based on file sizes, or properly manage storage space.

Laravel provides few options to get file size from path. In this tutorial, we will use the concept of getting file size using Storage class and File Facade classes. We need to assume that we have few files inside /public folder or /storage/app/public folder.

Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

File Inside Folders (Few Example Cases)

Let’s say we have an image file inside these folders:

/storage/app/public/images
/public/images

We will see the concept of finding size using Storage class and File class in all these above cases.

How To Get File Size: Using Storage Class

Here, we will use Storage facade class and it’s size method.

Assume we have a file named as 1.png inside /storage/app/public/images folder.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Storage;

class SampleController extends Controller
{
    public function index()
    {
        $fileSize = Storage::size('public/images/1.png');

        // File size in bytes
        dd($fileSize);
    }
}

Output

File size will be returned into bytes.

How To Get File Size: Using File Class

Here, we will use File facade class and it’s size method.

Assume we have a file named as 1.png inside /public/images folder.

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\File;

class SampleController extends Controller
{
    public function index()
    {
        $fileSize = File::size(public_path('images/1.png'));

        // File size in bytes
        dd($fileSize);
    }
}

Output

File size will be returned into bytes.
