PHP - Simple XML attributes problem - php

Question

I use PHP and Simple XML.
I use a loop that does not work like expected:
foreach($item->Image->attributes()->source as $key => $value)
{
echo $value;
}
In the foreach I try to tell that I want to get the "source" of the image which is listed in the attributes.
$item above is created with a loop around my code above foreach($xml_content->Section->Item as $item {}, (if you need to know where it came from)
My object looks like this:
object(SimpleXMLElement)#36 (4) {
["Text"]=>
string(15) "Vinbergs socken"
["Description"]=>
string(73) "Vinbergs socken ingick i Faurås härad och ligger i Falkenbergs kommun.
"
["Url"]=>
string(44) "http://sv.wikipedia.org/wiki/Vinbergs_socken"
["Image"]=>
object(SimpleXMLElement)#38 (1) {
["#attributes"]=>
array(3) {
["source"]=>
string(113) "http://upload.wikimedia.org/wikipedia/commons/thumb/2/25/Faur%C3%A5s_Vinberg.svg/50px-Faur%C3%A5s_Vinberg.svg.png"
["width"]=>
string(2) "50"
["height"]=>
string(2) "41"
}
}
}
What is wrong with my loop in the beginning of my post?

Answer 1

Your are trying to iterate a string, not an array
$item->Image->attributes()->source
To iterate all the attributes of the Image element, use
foreach ($item->Image->attributes() as $attributeName => $attributeValue) {
If you just want to output the value of the source attribute, do not iterate but use the shorthand
echo $item->Image['source']
See this demo and the SimpleXml Basic Usage Examples in the PHP Manual
