Filesystem.php

TLDR

The Filesystem.php file in the Illuminate\Filesystem namespace provides a class called Filesystem that offers various methods for file and directory operations. It supports operations such as checking file or directory existence, getting file contents, writing file contents, moving files, copying files and directories, creating directories, deleting files and directories, and more.

Methods

Determines if a file or directory exists.

missing

Determines if a file or directory is missing.

get

Gets the contents of a file.

json

Gets the contents of a file as decoded JSON.

sharedGet

Gets the contents of a file with shared access.

getRequire

Gets the returned value of a file.

requireOnce

Requires the given file once.

lines

Gets the contents of a file one line at a time.

hash

Gets the hash of the file at the given path.

put

Writes the contents of a file.

replace

Writes the contents of a file, replacing it atomically if it already exists.

replaceInFile

Replaces a given string within a given file.

prepend

Prepends to a file.

append

Appends to a file.

chmod

Gets or sets UNIX mode of a file or directory.

delete

Deletes the file at a given path.

move

Moves a file to a new location.

copy

Copies a file to a new location.

link

Creates a symlink to the target file or directory.

relativeLink

Creates a relative symlink to the target file or directory.

name

Extracts the file name from a file path.

basename

Extracts the trailing name component from a file path.

dirname

Extracts the parent directory from a file path.

extension

Extracts the file extension from a file path.

guessExtension

Guesses the file extension from the mime-type of a given file.

type

Gets the file type of a given file.

mimeType

Gets the mime-type of a given file.

size

Gets the file size of a given file.

lastModified

Gets the file's last modification time.

isDirectory

Determines if the given path is a directory.

isEmptyDirectory

Determines if the given path is a directory that does not contain any other files or directories.

isReadable

Determines if the given path is readable.

isWritable

Determines if the given path is writable.

hasSameHash

Determines if two files are the same by comparing their hashes.

isFile

Determines if the given path is a file.

glob

Finds path names matching a given pattern.

files

Gets an array of all files in a directory.

allFiles

Gets all of the files from the given directory (recursive).

directories

Gets all of the directories within a given directory.

ensureDirectoryExists

Ensures a directory exists.

makeDirectory

Creates a directory.

moveDirectory

Moves a directory.

copyDirectory

Copies a directory from one location to another.
