因此，当我调用此函数ispis（）时，它不做任何事情，但当我在函数__constructor内部回显时，它会显示输入的所有内容的正确值。此外，当我评论上面的前三行// $ daniel = new User（＆＃34; ivan＆＃34;，＆＃34; 22＆＃34;）;行和取消注释，ispis（）工作正常。如果有人能向我解释为什么会这样，那会很好。 Tnx提前:)）

Answer 1

根据代码的外观，您尝试将两个新用户实例传递给新用户（“daniel”）。

所以基本上用户期待4个参数（年龄，名字，身高，体重）。你已经正确地创建了Luka和Ivan，但是在尝试创建Daniel时，你将这两个用户作为参数传递。当你想要年龄，名字，身高和体重时，你会给它Luka和Ivan。

如果您只想将数组传递给构造函数，只需将其作为参数传递给新实例：

<?php
class User {

    public $name;
    public $age;
    public $height;
    public $weight;

    function __construct($args){

        $this->age = $args['age'];
        $this->name = $args['name'];
        $this->height = $args['height'];
        $this->weight = $args['weight'];

    }

    function getAge() {
        return $this->age;
    }
}

$question_array = [
    'name' => 'Daniel',
    'age' => '22',
    'weight' => '174',
    'height' => '68'
];

$daniel = new User($question_array);
echo $daniel->getAge(); // 22

?>

Answer 2

Robert刚回答，他的方法是我在个人MVC中用来定义构造的方法，或者在另一种方式中我也总是在我的MVC中使用这种方法：P ... 顺便说一下，我认为伊万你对课程感到困惑......

class User{

public $name ;
public $age;
public $height ;
public $weight ;

 function __construct($array){

    if (is_array($array)){
        foreach($array as $k=>$v){
            $this->$k = $v;
        }
     }

  }
  public function ispis(){

      print 'NAME :' .$this->name .' AGE : ' .$this->age.' HEIGHT : ' .$this->height .' WEIGHT : ' .$this->weight.'<br>';

  }

}

 $arrayOne = ['name'=>"Ivan",'age'=>"22",'height'=>"174",'weight'=>"68"];
 $arrayTwo = ['name'=>"Luke",'age'=>"23",'height'=>"174",'weight'=>"68"];

  $ivan = new User($arrayOne);
  $luka = new User($arrayTwo);
  $ivan->ispis();
  $luka->ispis();

Answer 3

你的问题看起来有点模棱两可，但也许你想从一组参数中创建一个对象。

<?php
class User {

    public $name;
    public $age;

    public function __construct($name, $age)
    {
        $this->name = $name;
        $this->age  = $age;
    }

    public function echoAge()
    {
        echo $this->age;
    }
}

$args  = ['Leonard', 21];
$bones = new User(...$args);
$bones->echoAge();

输出：

如何将数组传递给php中的类？
