I am using the Amazon API to get some XML data, which is then passed through the json_decode() function.
Here are two samples of the data that is returned:
[BrowseNodes] => Array
(
[Request] => Array
(
[IsValid] => True
[BrowseNodeLookupRequest] => Array
(
[BrowseNodeId] => 2645269011
[ResponseGroup] => BrowseNodeInfo
)
)
[BrowseNode] => Array
(
[BrowseNodeId] => 2645269011
[Name] => Featured Categories
[Children] => Array
(
[BrowseNode] => Array
(
[0] => Array
(
[BrowseNodeId] => 3741261
[Name] => Cooktops
)
[1] => Array
(
[BrowseNodeId] => 3741271
[Name] => Dishwashers
)
[2] => Array
(
[BrowseNodeId] => 3741331
[Name] => Freezers
)
[3] => Array
(
[BrowseNodeId] => 2399939011
[Name] => Ice Makers
)
)
)
and
[BrowseNodes] => Array
(
[Request] => Array
(
[IsValid] => True
[BrowseNodeLookupRequest] => Array
(
[BrowseNodeId] => 3774781
[ResponseGroup] => BrowseNodeInfo
)
)
[BrowseNode] => Array
(
[BrowseNodeId] => 3774781
[Name] => Vitamin D
[Children] => Array
(
[BrowseNode] => Array
(
[BrowseNodeId] => 6936848011
[Name] => D3
)
)
I am then using this code to obtain data for each of the children:
if(isset($result['BrowseNodes']['BrowseNode']['Children'])){
$childs = $result['BrowseNodes']['BrowseNode']['Children']['BrowseNode'];
foreach($childs as $child){
$browsenodeid = $child['BrowseNodeId'];
$name = $child['Name'];
}
}
Everything works fine in the first sample, but in the second one, I am getting the following errors:
Warning: Illegal string offset 'BrowseNodeId'
Warning: Illegal string offset 'Name'
If I echo $browsenodeid and $name in the second example, it gives me 6 and D as the output.
Any ideas as to what I am doing wrong? I am quite confused; to me the data I am looping through in both cases seems to be the same, the only difference being that in the first case, the array has 4 elements and in the second it has 1 element.
Thanks in advance.
