Leaf FS

This is a simple functionality inspired by node js' FileSystem(fs) module. Leaf FS aims to make directory and file management much simpler than what you're currently used to, so as to speed up and ease the dev process.

Leaf FS allows you to read/write to file, create, rename, copy and paste files/directories all with just a few lines of code. All this is performed while maintaining Leaf's simplicity.


You can install leaf fs through composer:

composer require leafs/fs

or with leaf cli:

leaf install fs

FS Directory Methods


This will create a new directory in the current directory

Let's take this directory structure below, we initialise Leaf FS in our index.php file.


In our index.php file:


After running this code, this is our new directory structure



renameFolder is used to rename a directory. It takes in two parameters: the directory you want to rename and it's new name/path.

FS::renameFolder("home/new", "home/items");


deleteFolder is used to delete a directory. It takes in two parameters: the directory you want to delete.

FS::deleteFolder("new", "items");
FS::deleteFolder("home/new", "home/items");


listDir returns an array of all the files/folders in a directory. It takes in the directory to list and a search pattern eg: *.php. Also note that all folders end with a '/'

FS::listDir("home/new", "*.txt");


This method lists all the folders in a particular directory.


FS File Methods


createFile is used to create a new file in the current directory. It takes in the filename or path+filename. If the file already exists, it gives the new file a different name.



writeFile is used to add content to a file, if the file already has content, all the content in there is replaced with the new content. Also, if the file doesn't exist, it will be created and all the content will be added to it. It takes in 2 parameters, the name/path+name of the file and the content;

FS::writeFile("items.txt", "Hello");
FS::writeFile("items.txt", [
  "name" => "Item 1"
FS::writeFile("items.txt", 1);


append is almost exactly the same as writeFile, except that instead of replacing the content in a file, it adds to the end of it.

$data = FS::append("items.txt", "Item name");


prepend is almost exactly the same as writeFile, except that instead of replacing the content in a file, it adds to the begining.

$data = FS::prepend("items.txt", "Item name");


readFile returns the data found in a file. It takes 1 parameter: the file name/path+file name.

$data = FS::readFile("./home/items.txt");


renameFile renames a file. It takes 2 parameter: the file name/path+file name to rename and it's new name.

$data = FS::renameFile("./home/items.txt", "home/products.txt");


deleteFile deletes a file. It takes 2 parameter: the file name/path+file name to delete.

$data = FS::deleteFile("./home/items.txt");


copyFile copies a file from the current directory to another directory. It takes in 3 parameters: the filename, the new path + filename and whether to rename the file if it exists in the new directory. The 3rd parameter is optional, if nothing is passed for the 3rd parameter, it will rename the file. Pass in true to rename the file if it already exists, false to override the file content(default is true).

$data = FS::copyFile("items.txt", "./home/");
$data = FS::copyFile("items.txt", "./home/", false);


Recursively copy through a folder.

FS::deepCopy("source", "destination");


Copy a file, or recursively copy a folder and its contents. Based on Aidan Lister's copyr

$permissions = 0755;
FS::superCopy("source", "destination", $permissions);


cloneFile also copies a file from the current directory to another directory, but unlike copyFile, cloneFile includes the filename, and it takes in 2 parameters: the filename and the path+filename to clone to.

$data = FS::cloneFile("items.txt", "./home/products.txt");


moveFile also moves a file from the current directory to another directory, it takes in 2 parameters: the filename and the path to move to.

$data = FS::moveFile("items.txt", "./home/");


This method allows you to get all of the files from the given directory (recursive). It takes in the directory to search and whether to show hidden files or not.

$files = FS::allFiles("records", false);


This method was previously upload. In v2.4, uploadFile has received a lot of fixes and new features. Also the older upload method has been removed.

uploadFile as the name suggests is a method that makes file uploading a breeze. This is the main highlight of Leaf\FS in v2.4. Also unlike in earlier versions, uploadFile supports more type of files.

It takes in 3 parameters:

  • The file to upload
  • The path to save the file
  • Config for file upload
$profilePic = $request->files("profile_pic");

// file upload
Leaf\FS::uploadFile($profilePic, "./images/");

One amazing thing about FS is that it can detect the type of file you're trying to upload and handle it accordingly, so you don't need to worry about that. Below is a table of common file types which are automatically detected.

File TypeCommon Extensions
image'jpg', 'jpeg', 'png', 'gif', 'webp', 'apng', 'tif', 'tiff', 'svg', 'pjpeg', 'pjp', 'jfif', 'cur', 'ico'
video'mp4', 'webm', 'swf', 'flv'
audio'wav', 'mp3', 'ogg', 'm4a'
text'txt', 'log', 'xml', 'doc', 'docx', 'odt', 'wpd', 'rtf', 'tex', 'pdf'
presentation'ppsx', 'pptx', 'ppt', 'pps', 'ppsm', 'key', 'odp'
compressed'zip', 'rar', 'bz', 'gz', 'iso', 'tar.gz', 'tgz', 'zipx', '7z', 'dmg'
spreadsheet'ods', 'xls', 'xlsx', 'xlsm'
application'apk', 'bat', 'cgi', 'pl', 'com', 'exe', 'gadget', 'jar', 'msi', 'py', 'wsf'

You can open an issue if you think there should be a new category or if an important extension is not present here.

Upload Config:

You can configure file uploads to behave the way you want it to, and that's the 3rd parameter it takes in.

Leaf\FS::uploadFile($profilePic, "./images/", []);

Config is an array that takes in particular properties:

Leaf\FS::uploadFile($profilePic, "./images/", [
  "verify_dir" => true

This is a list of config options.

Config NameDescriptionPossible Values
uniqueIf true, a timestamp is added to filenametrue, false
verify_dirAdd error if upload directory is invalidtrue, false
verify_fileAdd error if same filename existstrue, false
max_file_sizeSet maximum file size in bytes, default: 10mbinteger
file_typeSet file type if it's not included in default liststring
validateValidate file type for invalid extensions: Only works with the default extensionstrue, false

If the file upload is successful, it returns the filename, you can perform whatever operation you need on the filename, if it fails you can access the errors through the errors method. Refer to error handling for this part.

$filename = FS::uploadFile($profilePic, "./images/", []);


When the file successfully uploads, records on the file details are shelved. You can access these with the uploadInfo method. It takes in one optional parameter, the name of the file whose info you want to return.

// returns info on all uploaded files (associative array)
$uploadInfo = Leaf\FS::uploadInfo();

// returns info on only selected file
$profileInfo = FS::uploadInfo($filename);


Get or set UNIX mode of a file or directory.

$mode = FS::chmod("items.txt");
FS::chmod("items.txt", ...);

Create a symlink to the target file or directory. On Windows, a hard link is created if the target is a file.

FS::link("items.txt", "items");


Extract the file name from a file path.

$name = FS::name("works/log.txt");


Extract the trailing name component from a file path.

$name = FS::basename("works/log.txt");


Extract the parent directory from a file path.

$dirname = FS::dirname("works/log.txt");


Extract the file extension from a file path.

$extension = FS::extension("works/log.txt");


Get the file type of a given file.

$type = FS::type("works/log.txt");


Get the file size of a given file.

$size = FS::size("works/log.txt");


Just like most leaf modules, fs also has an errors method which returns any errors that fs might have run into during an operation.

$errors = FS::errors();
