在php7中，匿名类现在可以使用%uA0new%uA0class%uA0来定义。匿名类可以使用来代替完整的类定义。
示例
<?php
interface Logger {
public function log(string $msg)
}
class Application {
private $logger
public function getLogger(): Logger {
return $this->logger
}
public function setLogger(Logger $logger) {
$this->logger = $logger
}
}
$app = new Application
$app->setLogger(new class implements Logger {
public function log(string $msg) {
print($msg)
}
})
$app->getLogger()->log("My first Log Message")
?>
这将在浏览器产生输出以下结果-
My first Log Message
