本文实例讲述了PHP7匿名类的用法。分享给大家供大家参考,具体如下:
<?php /** * Created by PhpStorm. * User: Itboot * Date: 2019/1/17 * Time: 18:15 */ class An { private $num; protected $age = 15; public function __construct() { $this->num = 1; } protected function bar(): int { return 10; } public function drive() { return new class($this->num) extends An{ protected $id; public function __construct($num) { $this->id = $num; } public function ea() { return $this->id + $this->age + $this->bar(); } }; } } echo (new An())->drive()->ea();
<?php $fun = function (){ print '这是匿名函数'. PHP_EOL; }; $fun(); class Animal { public $num; public function __construct(...$args) { $this->num = $args[0]; } public function getValue($su): int { return $this->num + $su; } } $an = new Animal(4); echo $an->getValue(12) . PHP_EOL; echo '匿名类'. PHP_EOL; echo (new class(11) extends Animal{})->getValue(12);
希望本文所述对大家PHP程序设计有所帮助。
