Simple classes to handle Filesystem operations.

Installation

Install it using composer

composer require tarsana/filesystem

Handeling Files and Directories

The Filesystem class was designed to be used easily and support call chaining which makes the code more readable.

// Create a Filesystem instance given a root path
$fs = new Tarsana\Filesystem('path/to/fs/root/directory');

Checking Paths

Maybe you need to check if a specific path is a file

if ($fs->isFile('path'))

or a directory

if ($fs->isDir('path'))

or you just want to know it exists, no matter it's a file or directory

if ($fs->isAny('path'))

What if you need to check multiple paths at once ?

if ($fs->areFiles(['path1', 'path2', 'path3']))
if ($fs->areDirs(['path1', 'path2', 'path3']))
if ($fs->areAny(['path1', 'path2', 'path3']))

But what if you want to know the type of a path without having to do multiple checks ?

$fs->whatIs('path-pattern')

You can use wildcard pattern as argument to this function and the result will be:

'file': if a single file corresponds to the pattern.
'dir': if a single directory corresponds to the pattern.
'collection': if multiple files and/or directories correspond to the pattern.
'nothing': if nothing corresponds to the pattern.

Finding Files and Directories

Now what if you want to get all files and directories corresponding to a pattern ?

$collection = $fs->find('pattern'); // a Collection instance

foreach ($collection->asArray() as $fileOrDir) {
	// Handle the file or directory
}

You can also manipulate the collection

$collection->count(); // number of elements
$collection->add($fs->file('path/to/file')); // add new element to the collection
$collection->contains('path'); // checks if the collection contains an element with that path
$collection->remove('path'); // remove the element having the path from the collection

$collection->files(); // a new collection containing only files
$collection->dirs(); // a new collection containing only directories

$collection->first(); // the first element
$collection->last(); // the last element

$collection->paths(); // array of paths of the files and directories
$collection->names(); // array of names of the files and directories

Handling Files

Well, to handle a file, you should get it first

$file = $fs->file('path/to/file');

Notice that this will throw an exception if the file is not found. If you want to create it when missing; specify true in the second argument

$file = $fs->file('path/to/file', true);

You can also get or create multiple files at once

$files = $fs->files([
	'path/to/file1',
	'path/to/file2',
	'path/to/file3'
]); // specify the second argument as true if you want missing files to be created

foreach ($files->asArray() as $file) {
	// Handle the file
}

Now that you have the file, you can play with it

$file->name(); // get the name
$file->name('new-name.txt'); // renaming the file

$file->path(); // get the absolute path
$file->path('new/absolute/path'); // moving the file

$file->content(); // reading the content
$file->content('new content'); // writing to the file
$file->append('additional content'); // add content to the file

$file->hash(); // get the md5 hash of the content
$file->extension(); // get the extension (like "txt" or "php")

$file->perms(); // get the file permissions as string (like "0755")
$file->isWritable(); // check if the file is writable
$file->isExecutable(); // check if the file is executable

$copy = $file->copyAs('absolute/path/to/file-copy'); // Copy the file
$file->remove(); // Remove the file

Notice that all setters return the same instance to enable call chaining.

Handling Directories

Just like the file, you can get a directory like that

$dir = $fs->dir('path/to/dir'); // throws exception if the directory not found
$dir = $fs->dir('path/to/dir', true); // creates the directory if not found
$dirs = $fs->dirs([
	'path/to/file1',
	'path/to/file2',
	'path/to/file3'
]); // a collection containing directories

Having a directory, you can play with it

$dir->name(); // get the name
$dir->name('new-name'); // renaming the directory

$dir->path(); // get the absolute path
$dir->path('new/absolute/path'); // moving the directory

$dir->perms(); // get the directory permissions as string (like "0755")

$copy = $dir->copyAs('absolute/path/to/dir-copy'); // Copy the directory
$dir->remove(); // Remove the directory

$dir->fs(); // get a Filesystem instance having this directory as root

Notice that all setters return the same instance to enable call chaining.

Reading & Writing to Resources

Writer

Tarsana\Filesystem\Resource\Writer gives the possibility to write content to any resource.

// Default constructor uses STDOUT by default
$stdout = new Writer;
// Any writable resource can be used
$res = fopen('temp.txt', 'w');
$out = Writer($res);
// Or just give the path
$out = Writer('php://memory');

// Writing content
$out->write('Hello ')->write('World !');
// Writes "Hello World !" to the resource
$out->writeLine('Hi');
// Writes "Hi".PHP_EOL to the resource

// The resource is closed when the $out object is destructed
// But you can still close it before
$out->close();

Reader

Tarsana\Filesystem\Resources\Reader gives the possibility to read content from any resource. Constructors are the same as Writer but the default resource is STDIN.

$stdin = new Reader; // when no parameter is given, it uses STDIN by default

$stdin->read(); // reads the whole content of STDIN
$stdin->read(100); // reads 100 bytes from STDIN
$stdin->readUntil(' '); // reads until the first ' ' (space) or EOF
$stdin->readLine(); // reads until PHP_EOL or EOF
// If the STDIN is empty and we do
$stdin->blocking(false)->read();
// This will return immediately an empty string; no blocking !

Buffer

Tarsana\Filesystem\Resource\Buffer is a Reader and Writer at the same time. If no resource is given, it uses php://memory to store content.
