print_r( get_class_methods(‘test')); //或:print_r( get_class_methods($a)); 均返回:Array ( [0] => __construct [1] => getv ) echo ‘'; print_r( get_class_vars(‘test')); //返回:Array ( [v] => 2 ),和上面不一样,不能用print_r( get_class_methods($a)); echo ‘...
本方法的唯一参数是一个数组,其中包含按 array(‘property’ => value, …) 格式排列的类属性。 下面我们先来看看在没有加 __set_state() 情况按下,代码及运行结果如何: 上代码: class Person { public $sex; public $name; public $age; public function __construct($name="", $age=25, $sex='男...

$obj = (object) array(‘property1’ => value1, ‘property2’ => value2); “` 将一个关联数组转换为对象可以直接给对象的属性赋值,属性名称对应数组的键,属性值对应数组的值。 总结:在PHP中,可以使用箭头操作符、对象方法、构造函数、魔术方法和数组形式等多种方式给对象赋值,可以根据实际需求选择合适的...
3. 数组占位符:在PHP中,可以使用占位符来访问数组中的元素。例如,$array = [1, 2, 3]; echo “数组中的第一个元素是{$array[0]}”; 将输出”数组中的第一个元素是1″。 4. 对象占位符:在PHP中,可以使用占位符来访问对象的属性或调用方法。例如,$object = new MyClass(); echo “对象的属性值为...

__set_state () 方法的参数是一个包含所有属性值的数组,其格式为 array ('property'=> value,...) 在以下示例中,我们没有定义__set_state () 方法: <?php class Person { public $sex; public $name; public $age; public function __construct($name="", $age=25, $sex='Male') ...
