Please help me.. thank you in advance 请帮帮我..提前谢谢你
This should work for you: 这应该适合你:
(This is because you can't access a property which doesn't have a legal variable name, so you have to use curly syntax) (这是因为您无法访问没有合法变量名称的属性,因此您必须使用卷曲语法)
echo $response->{"@hotelId"};
You can read more about this in the manual: http://php.net/manual/en/language.variables.variable.php 您可以在手册中阅读更多相关信息: http : //php.net/manual/en/language.variables.variable.php
And a quote from there: 从那里引用:
Curly braces may also be used, to clearly delimit the property name. 也可以使用卷曲括号来清楚地界定属性名称。 They are most useful when accessing values within a property that contains an array, when the property name is made of mulitple parts, or when the property name contains characters that are not otherwise valid (eg from json_decode() or SimpleXML). 当访问包含数组的属性中的值,属性名称由多个部分组成时, 或者属性名称包含其他方式无效的字符时 (例如,来自json_decode()或SimpleXML),它们最有用。
