Watcher
A simple watcher library written by PHP.
Usage
Install using Composer
$ composer require mileschou/watcher
Watch file
Example of watch file
<?php
use Watcher\Watcher;
$watcher = new Watcher();
$watcher->setFile('file1', '/path/to/file');
$watcher->watch(function($alias, $file, $isInit) {
if ($isInit) {
return;
}
echo $file . ' is Changed';
});Run once
Example of run one time.
<?php
use Watcher\Watcher;
$watcher = new Watcher();
$watcher->setFile('file1', '/path/to/file');
$watcher->run(function($alias, $file) {
echo 'Show ' . $file;
});Container
You can using simple container, default will trans to ArrayObject
<?php
use Watcher\Watcher;
$container = ['something'];
$watcher = new Watcher($container);
$watcher->setFile('file1', '/path/to/file');
$watcher->run(function($alias, $file) {
/** @var ArrayObject $this */
$data = $this->getArrayCopy();
echo 'Container data is ' . $data[0]; // Will see 'something'
});Or using other container library.
<?php
use Watcher\Watcher;
$container = new \Pimple\Container();
$container['some-key'] = 'some-value';
$watcher = new Watcher($container);
$watcher->setFile('file1', '/path/to/file');
$watcher->run(function($alias, $file) {
/** @var \Pimple\Container $this */
$data = $this['some-key'];
echo 'Pimple container data is ' . $data; // Will see 'some-value'
});Strategy
Here are two Strategy can use
<?php
use Watcher\Strategy;
use Watcher\Watcher;
// Use inotify extension, it will throw exception if you do not installed
$strategy = new Strategy\Inotify();
// Use file system
$strategy = new Strategy\FileSystem();
$watcher = new Watcher();
$watcher->setStrategy($strategy);I guess that using inotify is faster. Actually, I don't know how to test performance.
