MagicMounter

MagicMounter, by Marvin Janssen (http://marvinjanssen.me), released in 2017.

MagicMounter can magically mount "anything". These mounts can then be universally accessed using any of PHP's file/stream functions via the magic:// stream wrapper. What makes MagicMounter unique is that it the underlying driver for a mount is transparent to the end-user. Thus, you may at one point mount a local directory at magic://production, and later mount a remote directory via FTP at the same mount point.

Because MagicMounter works as a stream wrapper, all the goodness that comes with streams is available. Think of all the stream functions, filters, iterators, and so forth. This fact arguably makes it one of the most powerful PHP FTP clients to boot, whilst staying rather succinct.

To mount:

Magic::mount(string $name,string $type,array $options);

Where:

$name: the name of the mount (as magic://name).
$type: the type of mount, which defines which underlying driver to load (e.g.: 'fs', 'ftp', 'ftps').
$options: optional driver-specific options, see the driver classes for more information.

Usage

Install via Composer:

composer require marvinjanssen/magicmounter

Download project as zip file and include:

require 'magicmounter/src/magicmounter.php'

Example code

// Local filesystem:

Magic::mount('backup','fs',['directory'=>'/media/backup']);

copy('./index.php','magic://backup/index.php');

Magic::unmount('backup');

// FTP:

Magic::mount('production','ftp',
	[
	'host' => 'ftp.example.com',
	'username' => 'user',
	'password' => 'password',
	'directory' => '/var/www'
	]);

copy('./index.php','magic://production/index.php');

Magic::unmount('production');

Drivers

MagicMounter currently comes with 3 drivers.

fs

Local filesystem driver.

Options:

directory: local directory to mount.

ftp

Standard FTP driver using built-in ftp_* functions. The driver implements as many file system features as the PHP FTP extension permits.

Options:

username: FTP username (default 'anonymous').
password: FTP password (default '').
port: FTP port (default 21).
directory: Optional directory (default '/').
timeout: FTP connection timeout (default 90).
measure_transfer: Attempt to measure transfers (default false).
exception_on_read_error: Throw an exception if reading fails (default false).

To retrieve measurements if measure_transfer is enabled, use:

$resource = fopen('magic://mount/file.ext','r');

// ...

Magic::quote($resource,'download_speed');
Magic::quote($resource,'bytes_downloaded');

ftps

Extends ftp but uses ftp_ssl_connect().

Options are the same as ftp.

Extending

Extending MagicMounter with your own drivers is easy. Create your own class in the MagicMounter\driver namespace and implement the MagicMounter\Driver interface. A good starting point is the MagicMounter\driver\Fs class. Having some knowledge of the PHP stream wrapper is recommended. Also, be sure that you implement as much as you can, to offer a well-rounded magic driver. (Support for fseek(), fopen(), touch(), rename(), stat(), fopen() modes, etc..)

You define any custom driver as long as it implements MagicMounter\Driver:

Magic::driver('custom','\My\CustomDriver');

Magic::mount('production','custom');
