# Mount Manager
|
||
|
|
|
||
|
|
Flysystem comes with a wrapper class to easily work with multiple file system instances
|
||
|
|
from a single object. The `League\Flysystem\MountManager` is an easy to use container allowing
|
||
|
|
you to simplify more complex cross file system interactions.
|
||
|
|
|
||
|
|
Setting up a Mount Manager is easy:
|
||
|
|
|
||
|
|
~~~ php
|
||
|
|
$ftp = new League\Flysystem\Filesystem($ftpAdapter);
|
||
|
|
$s3 = new League\Flysystem\Filesystem($s3Adapter);
|
||
|
|
$local = new League\Flysystem\Filesystem($localAdapter);
|
||
|
|
|
||
|
|
// Add them in the constructor
|
||
|
|
$manager = new League\Flysystem\MountManager([
|
||
|
|
'ftp' => $ftp,
|
||
|
|
's3' => $s3,
|
||
|
|
]);
|
||
|
|
|
||
|
|
// Or mount them later
|
||
|
|
$manager->mountFilesystem('local', $local);
|
||
|
|
~~~
|
||
|
|
|
||
|
|
Now we do all the file operations we'd normally do on a `Flysystem\Filesystem` instance.
|
||
|
|
|
||
|
|
~~~ php
|
||
|
|
// Read from FTP
|
||
|
|
$contents = $manager->read('ftp://some/file.txt');
|
||
|
|
|
||
|
|
// And write to local
|
||
|
|
$manager->write('local://put/it/here.txt', $contents);
|
||
|
|
~~~
|
||
|
|
|
||
|
|
This makes it easy to code up simple sync strategies.
|
||
|
|
|
||
|
|
~~~ php
|
||
|
|
$contents = $manager->listContents('local://uploads', true);
|
||
|
|
|
||
|
|
foreach ($contents as $entry) {
|
||
|
|
$update = false;
|
||
|
|
|
||
|
|
if ( ! $manager->has('storage://'.$entry['path'])) {
|
||
|
|
$update = true;
|
||
|
|
} elseif ($manager->getTimestamp('local://'.$entry['path']) > $manager->getTimestamp('storage://'.$entry['path'])) {
|
||
|
|
$update = true;
|
||
|
|
}
|
||
|
|
|
||
|
|
if ($update) {
|
||
|
|
$manager->put('storage://'.$entry['path'], $manager->read('local://'.$entry['path']));
|
||
|
|
}
|
||
|
|
}
|
||
|
|

## Specialized calls
|
||
|
|
|
||
|
|
### Copy
|
||
|
|
|
||
|
|
The copy method provided by the Mount Manager takes the origin of the file into account.
|
||
|
|
When it detects the source and destination are located on a different file systems it'll
|
||
|
|
use a streamed upload instead, transparently.
|
||
|
|
|
||
|
|
~~~ php
|
||
|
|
$mountManager->copy('local://some/file.ext', 'backup://storage/location.ext');
|
||
|
|
~~~
|
||
|
|
|
||
|
|
### Move
|
||
|
|
|
||
|
|
The `move` call is the multi-file system counterpart to `rename`. Where rename must be used on
|
||
|
|
the same file system, the `move` call provides the same conceptual behavior, but then on two
|
||
|
|
different file systems.
|
||
|
|
|
||
|
|
~~~ php
|
||
|
|
$mountManager->move('local://some/upload.jpeg', 'cdn://users/1/profile-picture.jpeg');
|
||
|
|
~~~
