README

A simple file locator library.

Summary

The FileLocator library was created to provide file locating capabilities to a larger project. It can be used in templating engines, configuration file loaders, and more.

Installation

Add it to your list of Composer dependencies:

$ composer require herrera-io/file-locator=1.*

Usage

The library includes FileSystemLocator, which can be used to search one or more directory paths. Either a single directory path, or an array of paths may be passed to the constructor.

<?php

use Herrera\FileLocator\Locator\FileSystemLocator;

$locator = new FileSystemLocator('/path/to/dir');
$locator = new FileSystemLocator(array(
    '/path/to/dir1',
    '/path/to/dir2',
    '/path/to/dir3' // etc
));

$file = $locator->locate('file.ini'); // return the first "file.ini" found
$files = $locator->locate('file.ini', false); // find all named "file.ini"

You can also create your own custom file locator by implementing the interface, LocatorInterface. All locator classes bundled in the library also implement this interface, allowing drop-in replacement.

<?php

use Herrera\FileLocator\Locator\LocatorInterface;

class MyLocator implements LocatorInterface
{
    public function locate($file, $first = true)
    {
        // do something to locate $file

        // if $first is true, return the first matching result
            // if nothing is found, return null

        // if $first is false, generate a list of found $file(s) and return it
            // if nothing is found, return an empty array
    }
}

You may use one or more file locator classes together by using the Collection class. This can be used to chain together one or more file locators, and may be used in place of an actual file locator.

<?php

use Herrera\FileLocator\Collection;
use Herrera\FileLocator\Locator\FileSystemLocator;
use My\Library\CustomLocator;

$locators = new Collection();
$locators->add(new FileSystemLocator('/path/to/dir'));
$locators->add(new CustomLocator());

$file = $locator->locate('file.ini'); // return the first "file.ini" found
$files = $locator->locate('file.ini', false); // find all named "file.ini"
