In PHP, how do I copy traits for production systems?

In PHP, traits are a mechanism for code reuse in single inheritance languages such as PHP. Since traits cannot be instantiated on their own and are intended to be included within classes, you can use them to create a production system that promotes DRY (Don't Repeat Yourself) principles. Here's how you can create and utilize traits effectively.

To copy traits in production systems, you would typically define your traits and then use them in your class definitions. Below is an example:

<?php trait Logger { public function log($message) { echo "Log: " . $message . "<br>"; } } trait FileOperations { public function createFile($filename) { // logic to create a file $this->log("File '{$filename}' created"); } } class FileManager { use Logger, FileOperations; public function createAndLog($filename) { $this->createFile($filename); } } $fileManager = new FileManager(); $fileManager->createAndLog('example.txt'); ?>
