PHP简单XML元素对象 - 如何获取字符串值

Question

How do I get the values of the follow array fields in php? When I do a print_r function on a two dimensional array, I get the following result:

[title] => SimpleXMLElement Object ( ) [date] => SimpleXMLElement Object ( )

How do I get the string value of title and date? I've tried casting them with

(string)

, however this didn't work.

Answer 1

You need to access the attributes of the SimpleXMLElement Object. Say you have an instance named entry with child title you type

(string) $entry->title;
