post('https://external-api.com/data', ['json' => $data]); } } class LocalDatabaseAdapter { public static function insert($data) { $db = new PDO('mysql:host=localhost;dbname=my-db', 'username', 'password'); $stmt = $db->prepare("INSERT INTO my_table VALUES (?, ?, ?, ?)"); $stmt->execute([ $data['id'], $data['name'], $data['email'], $data['phone'] ]); } } class DataProcessor { public function processData($id, $name, $email, $phone) { $data = [ 'id' => $id, 'name' => $name, 'email' => $email, 'phone' => $phone ]; LocalDatabaseAdapter::insert($data); ExternalAPIAdapter::post($data); } }In the above example, the 'DataProcessor' class processes the data and uses the static methods of 'LocalDatabaseAdapter' and 'ExternalAPIAdapter' to insert and push the data respectively. The PHP static adapter is not a package or library in itself. It is rather a design pattern that can be used in any PHP codebase, regardless of whether it uses any package or library. However, usage of external libraries such as GuzzleHttp, PDO, etc., is very common while implementing such patterns.
