推荐一款PHP支持文件及文件夹增删改查的composer包，删除目录，删除文件等

文件及文件夹的操作是必不可少的，删除文件，删除文件夹，追加文件等，虽然PHP有自带函数可以实现大部分功能，这里还是要给大家推荐一款支持目录操作的composer包。

```
composer require league/flysystem
```

使用说明：

```
写文件
try {
    $filesystem->write($path, $contents, $config);
} catch (FilesystemError | UnableToWriteFile $exception) {
    // handle the error
}

写文件流
try {
    $filesystem->writeStream($path, $stream, $config);
} catch (FilesystemError | UnableToWriteFile $exception) {
    // handle the error
}

读取
try {
    $response = $filesystem->read($path);
} catch (FilesystemError | UnableToReadFile $exception) {
    // handle the error
}

删除
try {
    $filesystem->delete($path);
} catch (FilesystemError | UnableToDeleteFile $exception) {
    // handle the error
}

删除目录
try {
    $filesystem->deleteDirectory($path);
} catch (FilesystemError | UnableToDeleteDirectory $exception) {
    // handle the error
}

读取目录下文件
try {
    $listing = $filesystem->listContents($path, $recursive);

/** @var \League\Flysystem\StorageAttributes $item */
    foreach ($listing as $item) {
        $path = $item->path();

if ($item instanceof \League\Flysystem\FileAttributes) {
            // handle the file
        } elseif ($item instanceof \League\Flysystem\DirectoryAttributes) {
            // handle the directory
        }
    }
} catch (FilesystemError $exception) {
    // handle the error
}

文件是否存在
try {
    $fileExists = $filesystem->fileExists($path);
} catch (FilesystemError | UnableToRetrieveMetadata $exception) {
    // handle the error
}

文件最后被访问时间
try {
    $lastModified = $filesystem->lastModified($path);
} catch (FilesystemError | UnableToRetrieveMetadata $exception) {
    // handle the error
}

文件或者文件夹大小
try {
    $fileSize = $filesystem->fileSize($path);
} catch (FilesystemError | UnableToRetrieveMetadata $exception) {
    // handle the error
}

创建目录
try {
    $filesystem->createDirectory($path, $config);
} catch (FilesystemError | UnableToCreateDirectory $exception) {
    // handle the error
}

剪切
try {
    $filesystem->move($source, $destination, $config);
} catch (FilesystemError | UnableToMoveFile $exception) {
    // handle the error
}

复制
try {
    $filesystem->copy($source, $destination, $config);
} catch (FilesystemError | UnableToCopyFile $exception) {
    // handle the error
}

```
