你们都需要做的是,在您的“植被功能”之前添加“和;”作为参考。

public function &__get ( $index )

Struggled with this one for a while.

我怀有同样的错误,没有你的整个法典,很难确切地确定如何加以确定,而是由没有固定功能造成的。

The way that I have gotten around it in the past is I have done things like this:

$user = createUser();
$role = $user->role;
$role->rolename =  Test ;

现在请你这样做:

echo $user->role->rolename;

页: 1 试验

虽然我很晚才参加这次讨论,但我认为这或许对今后某个人有用。

我面临类似的情况。 对那些想不确定和重新确定变量的人来说,最容易的工作就是这样做。 我确信,从其他答复和《综合手册》中可以清楚地看出为什么不这样做。 为我工作的最简单工作是:

假设:

1. $object is the object with overloaded __get and __set from the base class, which I am not in the freedom to modify.
2. shippingData is the array I want to modify a field of for e.g. :- phone_number

// First store the array in a local variable.
$tempShippingData = $object->shippingData;

unset($object->shippingData);

$tempShippingData[ phone_number ] =  888-666-0000  // what ever the value you want to set

$object->shippingData = $tempShippingData; // this will again call the __set and set the array variable

unset($tempShippingData);

说明:这一解决办法是迅速解决该问题并获得可变复制的解决方案之一。 如果阵列过于hum,则最好强制改写__get/code>方法,以退回一个比较昂贵的大型阵列。
