php7对象集合+属性

Question

如何在php中创建对象（如c＃）

对于具有3个属性的示例用户<​​/ p>

   class Users
{
    private $name;
    private $age;
    private $sex;

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

如何在集合中添加用户 然后循环用户集合以获取

$user->name
$user->age
$user->sex

谢谢

从你给出的例子来看，它可能是这样实现的：

class User
{
  const
    SEX_M = 1,
    SEX_F = 2
  ;

  private
    $name,
    $age,
    $sex
  ;

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

  public function dump()
  {
    echo "name: $this->name, age: $this->age, sex: "
       . ($this->sex === User::SEX_M ? 'm' : 'f') . "<br>\n";
  }
}

$collection = array();
$collection[] = new User('Tom'  , 10, User::SEX_M);
$collection[] = new User('Jerry', 11, User::SEX_F);

foreach ($collection as $user)
  $user->dump();
