This article describes the Laravel5.1 framework file management operations. Share it for your reference, as follows:
Laravel provides a very useful file system that is convenient for managing folders and files, and supports drivers such as Amazon S3 and Rackspace cloud storage.
1 Configuration
The file system configuration file is in config/ and its annotations are written very clearly. In addition, you can create a new disk in the disks array:
<?php
return [
/*
|--------------------------------------------------------------------------
| Default Filesystem Disk
|--------------------------------------------------------------------------
|
| Here you may specify the default filesystem disk that should be used
| by the framework. A "local" driver, as well as a variety of cloud
| based drivers are available for your choosing. Just store away!
|
| Supported: "local", "ftp", "s3", "rackspace"
|
*/
'default' => 'local',
/*
|--------------------------------------------------------------------------
| Default Cloud Filesystem Disk
|--------------------------------------------------------------------------
|
| Many applications store files both locally and in the cloud. For this
| reason, you may specify a default "cloud" driver here. This driver
| will be bound as the Cloud disk implementation in the container.
|
*/
'cloud' => 's3',
/*
|--------------------------------------------------------------------------
| Filesystem Disks
|--------------------------------------------------------------------------
|
| Here you may configure as many filesystem "disks" as you wish, and you
| may even configure multiple disks of the same driver. Defaults have
| been setup for each driver as an example of the required options.
|
*/
'disks' => [
'local' => [
'driver' => 'local',
'root' => storage_path('app'),
],
'ftp' => [
'driver' => 'ftp',
'host' => '',
'username' => 'your-username',
'password' => 'your-password',
// Optional FTP Settings...
// 'port' => 21,
// 'root' => '',
// 'passive' => true,
// 'ssl' => true,
// 'timeout' => 30,
],
's3' => [
'driver' => 's3',
'key' => 'your-key',
'secret' => 'your-secret',
'region' => 'your-region',
'bucket' => 'your-bucket',
],
'rackspace' => [
'driver' => 'rackspace',
'username' => 'your-username',
'key' => 'your-key',
'container' => 'your-container',
'endpoint' => '/v2.0/',
'region' => 'IAD',
'url_type' => 'publicURL',
],
],
];
Generally speaking, local (local) storage is the most commonly used, so in particular, we can modify our root path by modifying 'root':
'local' => [
'driver' => 'local',
// 'root' => storage_path('app'), in /storage/app/ directory 'root' => public_path('uploads'), // in the public/uploads/ directory ],
2 Get the hard disk instance
To perform file management, we can obtain it through the disk method of the Storage facade, and then we can perform the operations we want:
public function index()
{
$disk = Storage::disk('local');
// Create a file $disk->put('', 'Laravel Storage');
}
3 File operations
3.1 Get the file
public function index()
{
// Get the disk instance $disk = Storage::disk('local');
// Remove the file $file = $disk->get('');
dd($file);
}
We can use the get() method to get the file and pass the file name in the form of a string, but we need an idea: if you want to get the file below the subdirectory, you need to pass the path, such as: $disk->get('subpath/.../.../.../.../');
3.2 Determine whether the file exists
public function index()
{
// Get the disk instance $disk = Storage::disk('local');
// Remove the file $exists = $disk->exists('');
dd($exists); // false
}
3.3 Obtain file information
File size:
public function index()
{
// Get the disk instance $disk = Storage::disk('local');
// Remove the file $size = Storage::size('/home/');
dd($size); // 4
}
Last modified time:
public function index()
{
// Get the disk instance $disk = Storage::disk('local');
// Remove the file $time = Storage::lastModified(''); // 1507701271
$time = Carbon::createFromTimestamp($time);
echo $time; // 2017-10-11 05:54:31
}
3.4 Save files
public function index()
{
// Get the disk instance $disk = Storage::disk('local');
//Save files $disk->put('', 'file2 content'); // Create a new file }
3.5 Copy Files
public function index()
{
// Get the disk instance $disk = Storage::disk('local');
// Copy the file The first parameter is the file to be copied, and the second parameter is where to copy it $disk->copy('home/','');
}
3.6 Move files
public function index()
{
// Get the disk instance $disk = Storage::disk('local');
// Copy the file The first parameter is the file to be moved, and the second parameter is where to move $disk->move('', 'home/');
}
3.7 Add content at the beginning/end of the file
public function index()
{
// Get the disk instance $disk = Storage::disk('local');
// Add at the beginning of the file $disk->prepend('', 'test prepend');
// Add at the end of the file $disk->append('', 'test append');
}
3.8 Delete files
public function index()
{
// Get the disk instance $disk = Storage::disk('local');
// Delete a single file $disk->delete('');
// Delete multiple files $disk->delete(['', '']);
}
4 Directory operations
4.1 Get the file in the directory
public function index()
{
// Get the disk instance $disk = Storage::disk('local');
$directory = '/';
// Get the file in the directory $files = $disk->files($directory);
// Get all files in the directory (including files in the subdirectory) $allFiles = $disk->allFiles($directory);
dd($files, $allFiles);
}
4.2 Get subdirectory
public function index()
{
// Get the disk instance $disk = Storage::disk('local');
$directory = '/';
// Get the subdirectory in the directory $directories = $disk->directories($directory);
// Get all subdirectories in the directory (including subdirectories under the subdirectories) $allDirectories = $disk->allDirectories($directory);
dd($directories, $allDirectories);
}
4.3 Create a directory
public function index()
{
// Get the disk instance $disk = Storage::disk('local');
// Create a directory $disk->makeDirectory('test');
$disk->makeDirectory('test1/test2');
}
4.4 Delete Directory
public function index()
{
// Get the disk instance $disk = Storage::disk('local');
// Delete the directory $disk->deleteDirectory('test');
$disk->deleteDirectory('test1/test2');
}
