解析错误：语法错误，意外的 T_OBJECT_OPERATOR

尝试将 myXml.xml 中的一些数据添加到字符串时，出现以下错误：解析错误：语法错误，意外的 T_OBJECT_OPERATOR。

    $xmlstr = file_get_contents('myXml.xml');
    $xml = new SimpleXMLElement($xmlstr); 

    foreach($xml->order as $order){
            $replace = array();
            $firstName = (string) $order->billing-address->first-name;
            $lastName = (string) $order->billing-address->last-name;
    }

我无法直接提供 XML，因为它包含敏感数据。

谢谢，山姆

I'm getting the following error when trying to add some data from myXml.xml to a string: Parse error: syntax error, unexpected T_OBJECT_OPERATOR.

    $xmlstr = file_get_contents('myXml.xml');
    $xml = new SimpleXMLElement($xmlstr); 

    foreach($xml->order as $order){
            $replace = array();
            $firstName = (string) $order->billing-address->first-name;
            $lastName = (string) $order->billing-address->last-name;
    }

I can't provide my XML directly as it contains sensitive data.

Thanks,
Sam

- 符号表示减法。要在属性名称中使用它，必须使用以下语法：

$firstName = (string) $order->{"billing-address"}->{"first-name"};
$lastName = (string) $order->{"billing-address"}->{"last-name"};

一般来说，最好使用 firstName、billingAddress 等作为属性名称来避免这种情况。请参阅CamelCase。然而，在这种情况下，您可能无法控制 XML 输入。

The - sign means subtraction. To use it in property names, you must use this syntax:

$firstName = (string) $order->{"billing-address"}->{"first-name"};
$lastName = (string) $order->{"billing-address"}->{"last-name"};

In general, it's probably better to use firstName, billingAddress, etc. as property names to avoid this. See CamelCase. In this case, however, you may have no control over the the XML input.
