I am kind of jacked here. I have a SimpleXML object that's been converted to an array. In one
of the nodes, for no reason I can see, the array is populated differently if there is only one
<order_item> than if there are multiple <order_item>s.
If there is just one, my $order_item array looks like this:
Array
(
[order_item_product_code] => 1300
[order_item_description] => 4x8 photo cards (set of 20)
)
But if there are multiple items, I get this:
Array
(
[0] => SimpleXMLElement Object
(
[order_item_product_code] => 1060
[order_item_description] => 4x5.3 trueDigital print(s)
)
[1] => SimpleXMLElement Object
(
[order_item_product_code] => 1300
[order_item_description] => 4x8 photo cards (set of 20)
)
)
See my problem? I can't foreach through those and process the items in the same way.
In case it matters, here is that snip of what the original XML looks like, it's all good:
<?xml version="1.0" encoding="UTF-8"?>
<order xmlns="http://xxxx.com/xxxx"
version="1.0">
<order_items>
<order_item>
<order_item_product_code finish="glossy">1060</order_item_product_code>
<order_item_description>4x5.3 trueDigital print(s)</order_item_description>
</order_item>
<order_item>
<order_item_product_code finish="glossy">1300</order_item_product_code>
<order_item_description>4x8 photo cards (set of 20)</order_item_description>
</order_item>
</order_items>
</order>
And here is the function I'm using to convert the XML to an array:
function xmlToArray($xml, $isChild = false) {
if($xml instanceof SimpleXMLElement) {
$xmlObject = $xml;
} elseif($isChild) {
return $xml;
} else {
try {
$xmlObject = new SimpleXMLElement($xml);
} catch(Exception $e) {
$string = $e->getMessage();
throw new Exception('Invalid XML found in ' . __FUNCTION__ . ' function on line
'.__LINE__.'.');
}
}
$children = (array)$xmlObject->children();
if(is_array($children)) {
if(count($children) == 0) {
$children = '';
} else {
foreach($children as $element => $value) {
$children[$element] = xmlToArray($value, true);
}
}
}
return $children;
}
Any suggestions?
