自分の場合は、下記にインストールしました。

「C:\Apache24\htdocs」に「test.php」を下記のコードで作成します。

<?php
use League\Flysystem\Filesystem as FlyFilesystem;
use League\Flysystem\Adapter\Local as FlyLocal;
use League\Flysystem\FileExistsException as FlyFileExistsException;

require_once __DIR__ . '/vendor/autoload.php';

//ファイルを読み込み表示
$fs = new FlyFilesystem(new FlyLocal(__DIR__));
$content = $fs->read('sample.txt');
print($content);

//ファイル書き込み(ファイルがなければ新規作成あれば更新)
try {
    $content = $fs->put('sample-white.txt', 'white word');
  } catch (FlyFileNotFoundException $e) {
    throw $e;
  }

<?php

use League\Flysystem\Filesystem as FlyFilesystem;

use League\Flysystem\Adapter\Local as FlyLocal;

use League\Flysystem\FileExistsException as FlyFileExistsException;

require_once __DIR__ . '/vendor/autoload.php';

//ファイルを読み込み表示

$fs = new FlyFilesystem(new FlyLocal(__DIR__));

$content = $fs->read('sample.txt');

print($content);

//ファイル書き込み(ファイルがなければ新規作成あれば更新)

try {

$content = $fs->put('sample-white.txt', 'white word');

} catch (FlyFileNotFoundException $e) {

throw $e;

}

「test.php」と同じ階層に「sample.txt」を下記の内容で作成しておきます。

hello world

1	hello world

実行結果を確認すると、読み込んだファイルの内容が表示され、「 sample-white.txt 」というファイルが作成されていることが確認できます。
