How do I design a plugin architecture in PHP?

Designing a plugin architecture in PHP allows for extensibility and modularity in your application. By following a systematic approach, you can create a robust system that accommodates third-party plugins seamlessly.

Example of Plugin Architecture in PHP

<?php interface PluginInterface { public function activate(); public function deactivate(); } class PluginManager { private $plugins = []; public function loadPlugin($pluginClass) { if (class_exists($pluginClass) && in_array('PluginInterface', class_implements($pluginClass))) { $plugin = new $pluginClass(); $plugin->activate(); $this->plugins[] = $plugin; } } public function unloadPlugin($plugin) { if (in_array($plugin, $this->plugins)) { $plugin->deactivate(); unset($this->plugins[array_search($plugin, $this->plugins)]); } } } class SamplePlugin implements PluginInterface { public function activate() { echo "SamplePlugin activated.<br>"; } public function deactivate() { echo "SamplePlugin deactivated.<br>"; } } $manager = new PluginManager(); $manager->loadPlugin('SamplePlugin'); ?>
