如何在没有多个构造函数的情况下处理 PHP 类中的多个初始化场景？

class Student {
    public function __construct($id) {
        $this->id = $id;
    }

    public function __construct(array $row_from_database) {
        $this->id = $row_from_database['id'];
        $this->name = $row_from_database['name'];
    }
}

class Student {
    public function __construct() {
        // Allocate resources here
    }

    public static function withID($id) {
        $student = new self();
        $student->id = $id;
        return $student;
    }

    public static function withRow(array $row) {
        $student = new self();
        $student->id = $row['id'];
        $student->name = $row['name'];
        return $student;
    }
}

$studentWithID = Student::withID(42);
$studentWithRow = Student::withRow(['id' => 42, 'name' => 'John']);
