“在标志处" @在SimpleXML对象中? [英] "At sign" @ in SimpleXML object?

问题描述

这是在典型的SimpleXMLElement对象上运行的print_r()的输出:

This is the output of print_r() run on a typical SimpleXMLElement object:

SimpleXMLElement Object
(
    [@attributes] => Array
        (

        )
)

@符号是什么意思?

推荐答案

这是 SimpleXMLElement 对象. "@attributes"行是属性的内部表示形式. XML元素.使用SimpleXML的功能从该对象获取数据，而不是直接与之交互.

This is a SimpleXMLElement object. The '@attributes' row is an internal representation of the attributes from the XML element. Use SimpleXML's functions to get data from this object rather than interacting with it directly.
