PHP: foreach warnings on simplexml

Question

PHP and XML question:

Here is the var_dump i get from parsed xml.

object(SimpleXMLElement)#47 (6) {
    ["link"]=> array(4) {
        ...
    }
    ["entry"]=> array(11) {
        ...
    }
}

However, when I use:

foreach ($parsedReturn->link as $item)

or,

foreach ($parsedReturn->entry as $item)

I get warnings as such:

PHP Warning: Invalid argument supplied for foreach()

Answer 1

“链接”可以是属性，因此您必须使用$parsedReturn['link'] 。
