How To Use

This is an implementation of local disk filesystem that allows you to work with local files.
First of all, you need to add this library to your project, so run:

composer require dnj/local-filesystem

File basic usage:

Read file:

<?php
use dnj\Filesystem\Local\File;

$file = new File('/etc/hosts');
$content = $file->read();
echo $content; // prints: 127.0.0.1       localhost 

Write file:

<?php
use dnj\Filesystem\Local\File;

$file = new File('~/adele-hello.txt');

$lyrics = <<<EOF
Hello, it's me
I was wondering if after all these years you'd like to meet
To go over everything
They say that time's supposed to heal ya, but I ain't done much healing
EOF;

try {
    $file->write($lyrics);
} catch (IOException $e) {
    // in case failed for any reason, like permission denied
}

Rename file:

<?php
use dnj\Filesystem\Local\File;


$file = new File('~/adele-hello.txt');
$lyrics = <<<EOF
I heard that you're settled down
That you found a girl and you're married now
I heard that your dreams came true
Guess she gave you things, I didn't give to you
Old friend, why are you so shy?
EOF;

try {
    $file->write($lyrics);
} catch (IOException $e) {
    // in case failed for any reason, like permission denied, ...
}


try {
    $file->rename('adele-someone-like-you.txt');

    // or you can completly move this file to new dest:
    $destFile = new File('/tmp/adele-someone-like-you.txt');
    $file->move($destFile);
} catch (IOException $e) {
    // in case failed for any reason, like permission denied, ...
}

Get size of file:

<?php
use dnj\Filesystem\Local\File;

$file = new File('/etc/hosts');
echo $file->size(); // prints the size of file in bytes

Existence of file and touch it (create it) if not exists:

<?php
use dnj\Filesystem\Local\File;

$file = new File('~/dnj-does-file-exists.txt');
echo 'file ' . ($file->exists() ? 'exists.' : 'not exists!');

if ($file->exists()) {
    echo 'File exists.' . PHP_EOL;
} else {
    echo 'File does not exists!' . PHP_EOL;
    // touch file
    $file->touch();
}

Delete file:

<?php
use dnj\Filesystem\Local\File;

$file = new File('~/test-dnj-delete-file.txt');
$file->write('Hello World!');
$file->delete();

Append to file:

<?php
use dnj\Filesystem\Local\File;

$file = new File('~/hello-world.txt');
$file->write('Hello');
echo $file->read(); // prints: Hello

$file->append(' World!');
echo $file->read(); // prints: Hello World!

Directory basic usage:

Check directory existence:

<?php
use dnj\Filesystem\Local\Directory;

$dir = new Directory('~/dnj/');
$dir->exists(); // return bool

Make directory:

<?php
use dnj\Filesystem\Local\Directory;

$dir = new Directory('~/dnj/');
$dir->make();
// or:
$recursive = true;
$dir->make($recursive, 0700); // make recursivley with permission 0700

Get files of directory:

<?php
use dnj\Filesystem\Local\Directory;

$dir = new Directory('/tmp/');
if ($dir->exists()) {
    // $directory->file() returns Generator of dnj\Filesystem\Local\File;
    $recursive = false;
    foreach ($directory->files($recursive) as $file) {
        echo $file->getPath() . PHP_EOL;
    }
}

Get directories of directory:

<?php
use dnj\Filesystem\Local\Directory;

$parent = new Directory('/tmp/');
if ($dir->exists()) {
    // $directory->directories() returns Generator of dnj\Filesystem\Local\Directory;
    $recursive = false;
    foreach ($parent->directories($recursive) as $directory) {
        echo $directory->getPath() . PHP_EOL;
    }
}

Get directories of directory:

<?php
use dnj\Filesystem\Local\Directory;

$dir = new Directory('/tmp/');
if ($dir->exists()) {
    // $directory->file() returns Generator of dnj\Filesystem\Local\File;
    $recursive = false;
    foreach ($directory->files($recursive) as $file) {
        echo $file->getPath() . PHP_EOL;
    }
}

Get items (files and directories) of directory:

<?php
use dnj\Filesystem\Local\Directory;

$dir = new Directory('/tmp/');
if ($dir->exists()) {
    // $directory->file() returns Generator of dnj\Filesystem\Local\File|dnj\Filesystem\Local\Directory;
    $recursive = false;
    foreach ($directory->items($recursive) as $node) {
        echo $node->getPath() . PHP_EOL;
    }
}

Get size of a directory:

<?php
use dnj\Filesystem\Local\Directory;

$dir = new Directory('/tmp/');
$recursively = true;
echo $dir->size($recursively); // prints the size of directory and all of it's contents

Get file from directory:

<?php
use dnj\Filesystem\Local\Directory;

$parent = new Directory('/tmp/');
$file = $parent->file('test-file.txt');
$file->write('https://dnj.co.ir');

echo $file->getPath(); // prints: /tmp/test-file.txt

Get directory from directory:

<?php
use dnj\Filesystem\Local\Directory;

$parent = new Directory('/tmp/');
$directory = $parent->file('test-directory');
$directory->make();

echo $directory->getPath(); // prints: /tmp/test-directory

Delete directory:

<?php
use dnj\Filesystem\Local\Directory;

$parent = new Directory('/tmp/');
$directory = $parent->file('test-directory');
$directory->make();

echo $directory->getPath(); // prints: /tmp/test-directory

$directory->delete(); // delete directory and all of it's content
