Path

code-distortion/path is a package that lets you deal with paths in a normalised way.

Installation

Install the package via composer:

composer require code-distortion/path

Usage

Use CodeDistortion\Path\Path;

$path = Path::new('/path/to/file.txt');

(string) $path;             // '/path/to/file.txt' (castable to a string)
$path->getDir();            // '/path/to/' (the dir as a new Path object)
$path->getFilename();       // 'file.txt'
$path->getFilename(false);  // 'file'
$path->getExtension();      // '.txt'
$path->getExtension(false); // 'txt'
$path->isAbsolute();        // true
$path->isRelative();        // false

Note: This package is designed to work with paths as strings in memory.

It doesn't deal with actual directories or files in any way. It doesn't care what's in the filesystem.

Note: This package takes the opinion that paths for directories end with a trailing slash, and paths for files do not.

If you want to make sure the input you're dealing with starts off specifically as a directory, or a file, you can specify this when creating the object.

// dir paths
Path::new('/path/to/thing/');   // '/path/to/thing/'
Path::newDir('/path/to/thing'); // '/path/to/thing/' (enforces that it's a dir)
// file paths
Path::new('/path/to/thing');      // '/path/to/thing'
Path::newFile('/path/to/thing/'); // '/path/to/thing' (enforces that it's a file)

You can remove unnecessary parts from a path.

Path::new('/a//b/.././c')->resolve(); // '/a/c' - removes unnecessary parts

You can add paths together, using one as the base.

Path::newDir('/path/to/uploads/')->add('my-file.txt');           // '/path/to/uploads/my-file.txt'
// make sure that your file doesn't break out from the base
Path::newDir('/path/to/uploads/')->add('../my-file.txt');        // '/path/to/uploads/my-file.txt'
// or allow it to break out
Path::newDir('/path/to/uploads/')->add('../my-file.txt', false); // '/path/to/my-file.txt'

Path will normalise forward and backslashes in the input, generating output in your native OS format (but the output separator can be overridden).

Path::newDir('\\path\\to\\file.txt');               // '/path/to/file.txt' (on a *nix OS)
Path::newDir('/path/to/file.txt');                  // '/path/to/file.txt' (on a *nix OS)
Path::newDir('/path/to/file.txt')->separator('\\'); // '\path\to\file.txt'

You can clone a Path object.

$pathA = Path::new('/path/to/file.txt');
$pathB = $pathA->copy();
$pathB !== $pathA; // true

The PathImmutable class is also available. Each change to a PathImmutable object returns a new instance. Both Path and PathImmutable implement CodeDistortion\Path\PathInterface.

$pathA = PathImmutable::newDir('/path/to/');
$pathB = $pathA->add('file.txt');
$pathA !== $pathB; // true
