Filepath

A simple class with some static methods for manipulating file paths properly regardless of system architecture

Motivation

I was working on a legacy PHP project where there was all sort of code like this:

    $routes = include(__DIR_ . DIRECTORY_SEPARATOR . 'src' . DIRECTORY_SEPARATOR . 'routes.php');

I then remembered that golang's filepath package would fluently join a url like this. So this is a port of the methods in golang's path/filepath package

Installation

    composer require nelwhix/filepath

Usage

• Join Method: Using the static 'join' method the code for the example earlier will look like this:

  $url = \Nelwhix\Filepath\Filepath::join(__DIR__, 'src', 'routes.php');
  $routes = include($url);

• Base method: The base method returns the last part of any filepath passed to it. Like this:

    \Nelwhix\Filepath\Filepath::base("/foo/bar/baz.js");
    // this will return "baz.js"

• Abs method: The abs method returns the absolute path to the filepath given:

    \Nelwhix\Filepath\Filepath::abs("Filepath.php");
    // this returns "\C:\Users\USER PC\Documents\Open Source contributions\filepath\src\Filepath.php"

• Dir method: The dir method returns the directory in a path:

    \Nelwhix\Filepath\Filepath::dir("/foo/bar/baz.js")
    // returns "/foo/bar"

• clean method: The clean method removes double and trailing slashes from a filepath e.g.

    \Nelwhix\Filepath\Filepath::clean("//dirty///path////");
    // this returns /dirty/path

• ext method: The ext method returns the extension of the file in the filepath. if a directory is passed it returns an empty string.

    \Nelwhix\Filepath\Filepath::ext("/src/routes.php");
    // returns ".php"

• split method: The split method returns an object that contains the directory and file from the filepath

    $split = \Nelwhix\Filepath\Filepath::split("./Documents/side-projects/filepath/composer.json");
    $split->dir; // ./Documents/side-projects/filepath
    $split->file; // composer.json

• walk method: The walk method takes a directory and a callback function to run on each file in the directory.

    Filepath::walk("C:\Users\USER PC\Documents\\300L books", function (\DirectoryIterator $param) {
        if($param->isDot()) return;
        echo $param->getFilename() . "\n";
    });

• glob method: The glob method returns all the files in a directory that match a pattern. To return all the files ending in ".php":

    Nelwhix\Filepath\Filepath::glob(".php", "side-projects/src");
    // returns an array containing the files matching the pattern
