What does this Laravel code output when storing a file locally?

Consider this Laravel code snippet that stores an uploaded file locally. What will be the output of echo $path; if the file is successfully stored?

Laravel

<?php
use Illuminate\Http\Request;

Route::post('/upload', function (Request $request) {
    $path = $request->file('photo')->store('images');
    echo $path;
});

A An error because the 'images' directory does not exist

B images/filename.ext (where filename.ext is the original file name)

C /storage/images/filename.ext (full URL path to the file)

D images/randomstring.ext (a random generated file name with original extension)

💡 Hint

Think about how Laravel generates file names when storing files with the store() method.

Laravel's store() method saves the file in the specified disk directory with a random generated file name, preserving the original extension. It returns the relative path including the directory and the generated file name.

Which option correctly configures the local disk in Laravel's filesystems.php?

You want to configure the local disk to store files in the storage/app/public directory and make them publicly accessible. Which configuration snippet is correct?

A 'local' => [ 'driver' => 'local', 'root' => public_path('storage'), 'url' => env('APP_URL').'/storage', 'visibility' => 'private', ]

B 'local' => [ 'driver' => 'local', 'root' => storage_path('app/public'), 'url' => env('APP_URL').'/public', 'visibility' => 'public', ]

C 'local' => [ 'driver' => 'local', 'root' => storage_path('app/public'), 'url' => env('APP_URL').'/storage', 'visibility' => 'public', ]

D 'local' => [ 'driver' => 'local', 'root' => storage_path('app'), 'url' => env('APP_URL').'/storage', 'visibility' => 'public', ]

💡 Hint

Check the root path and visibility settings for public access.

The local disk should point to storage/app/public for public files. The URL should map to /storage which is the public symlink. Visibility must be 'public' to allow access.

Why does this Laravel code fail to retrieve a file from local storage?

Given this code snippet, why does Storage::disk('local')->get('file.txt') throw an exception?

Laravel

<?php
use Illuminate\Support\Facades\Storage;

$content = Storage::disk('local')->get('file.txt');

A The file 'file.txt' does not exist in storage/app directory

B The 'local' disk is not defined in config/filesystems.php

C The get() method requires a full URL, not a relative path

D The Storage facade is not imported correctly

💡 Hint

Check if the file path is correct and the file exists in the expected directory.

The 'local' disk points to storage/app. If 'file.txt' is missing there, get() throws a FileNotFoundException.

What is the output of this Laravel code that deletes a file from local storage?

What will be the value of $deleted after running this code if the file exists?

Laravel

<?php
use Illuminate\Support\Facades\Storage;

$deleted = Storage::disk('local')->delete('oldfile.txt');
echo $deleted ? 'Deleted' : 'Not deleted';

A Throws an exception because delete() returns void

B Deleted

C Not deleted

D Throws an exception because the file path is incorrect

💡 Hint

Check what the delete() method returns when the file exists.

The delete() method returns true if the file was deleted successfully, otherwise false.

Which statement about Laravel's local disk storage is TRUE?

Select the correct statement about how Laravel handles local disk storage.

A The local disk stores files in the <code>storage/app</code> directory and requires a symbolic link to <code>public/storage</code> for public access

B Files stored using the local disk are accessible publicly by default without extra configuration

C Laravel automatically creates the <code>storage/app/public</code> directory if it does not exist when storing files

D The local disk driver encrypts files automatically before saving them to disk

💡 Hint

Think about how Laravel manages public access to files stored locally.

Laravel stores local disk files in storage/app. To make files publicly accessible, you must create a symbolic link from public/storage to storage/app/public using php artisan storage:link.
