This is an example of strategy pattern usage written in php. It helps to encapsulate a family of algorithms that perform similar functions, here we tried encapsulating various logging methods to an interface and making them interchangeable.
<?php
// Defining a family of algorithms
class LogToFile implements Logger
{
public function log($data)
{
var_dump('Log the data to a file.');
}
}
class LogToDatabase implements Logger
{
public function log($data)
{
var_dump('Log the data to a database.');
}
}
class LogToWebService implements Logger
{
public function log($data)
{
var_dump('Log the data to a web service.');
}
}
// encapsulating the algorithms and making them interchangeable
interface Logger
{
public function log($data);
}
class App
{
public function log($data, Logger $logger = null)
{
// setting log to file as a default logging method
$logger = $logger ?: new LogToFile();
$logger = $data;
}
}
$app = new App;
$app->log('Some logging info here.', new LogToDatabase);
