This class can manipulate paths of files and directories.

It can take a file name and uses the pathinfor function parse it into its parts like the base file name, name extension, directory parts, etc..

The class defines a setter function to alter just some parts of the file name.

It also returns the reassembled path when its value is retrieved as a string.

Simplifies the modification of a pathname, e.g. by changing file extension, directory name etc. Internally uses and "wraps" the functionality of the built-in pathinfo() function and presents it in what is hoped to be more memorable and intuitive.

Contents of this package

path.php contains class file\path. This class facilitates the manipulation of filenames; effectively it is a wrapper of PHP's built-in pathinfo() function.

modifier.php contains an example class that uses file\path.

phpdoc.dist.xml contains configuration information to generate automatic documentation using the phpDocumentor PEAR package.

tests/path_test.php contains some tests that can be run using phpunit:

$ phpunit tests/path_test.php

This test file also gives some examples of how the file\path class can be used.

Using file\path

The aim of this class is to make filename manipulation easy and intuitive.

Example 1: To rename a file in the current directory from foo.txt to foo.bak.

<?php require 'path.php';

$filename = 'foo.txt'; $backupfilename = new file\path($filename); $backupfilename->extension = 'bak'; rename($filename, $backupfilename); ?>

Example 2: to move a file to the system temporary directory:

<?php require 'path.php'; $filename = 'foo.txt'; $destination = new file\path($filename); $destination->set_temp_dir(); rename($filename, $destination); ?>

Example 3: to move a file to the current directory:

<?php require 'path.php';

$filename = new file\path('/var/www/foo.txt'); if ($filename->exists()) { $destination = new file\path($filename); $destination->set_current_dir(); rename($filename, $destination); } ?>

In order to remove part of the pathname, e.g. file extension or directory, simply assign NULL to that part:

<?php require 'path.php';

$filename = new file\path('/var/www/foo.txt'); $filename->dirname = $filename->extension = NULL; echo "$filename\n"; // outputs "foo\n" ?>

You can also build a pathname from scratch like this:

<?php require 'path.php';

$filename = new file\path; $filename->basename = 'foo.txt'; $filename->dir = '/var/www'; echo "$filename\n"; // outputs "/var/www/foo.txt" ?>
