我正在研究一个 PHP 类,该类的必填字段之一是 ( DropoffType
) 答案是REGULARPICKUP
。我可以在课堂上写这个然后把“=”放到REGULARPICKUP
?
例子:
protected $DropoffType = 'REGULARPICKUP';
你当然可以
class MyClass
{
protected $DropoffType = 'REGULARPICKUP';
}
或在构造函数中执行(这取决于您的具体情况是否可行):
class MyClass
{
protected $DropoffType;
public function __construct($Dropofftype = 'REGULARPICKUP')
{
$this->DropoffType = $Dropofftype;
}
}
或者,如果您有一个 set 功能:
class MyClass
{
protected $DropoffType;
public function setDropoffType($Dropofftype = 'REGULARPICKUP')
{
$this->DropoffType = $Dropofftype;
}
}
