Different array structures and breaking of foreach - php

Question

I generate XML file from dynamic content but I get 2 array types to get images:
First array type is when there are more than 1 images, example:
array(1) {
["Images"]=>
array(3) {
[0]=>
array(2) {
["Url"]=>
string(57) "http://example.net/image1.jpg"
["Default"]=>
bool(true)
}
[1]=>
array(2) {
["Url"]=>
string(57) "http://example.net/image2.jpg"
["Default"]=>
bool(false)
}
[2]=>
array(2) {
["Url"]=>
string(57) "http://example.net/image3.jpg"
["Default"]=>
bool(false)
}
}
}
Second type is when I had only 1 image, example:
array(1) {
["Images"]=>
array(2) {
["Url"]=>
string(57) "http://example.net/image111.jpg"
["Default"]=>
bool(true)
}
}
How I can make second type to use type of first array, because when I looping these arrays with foreach there is a problem with content. Is there any function to fix this or something?!
Edit:
This is the foreach now and it works:
$productImages = $product->appendChild($this->_xmlDoc->createElement('ProductImages'));
if(isset($productInfo['ProductImages'])) {
foreach($productInfo['ProductImages']['Images'] as $image) {
if(!is_array($image) && is_string($image)) {
$productImage = $productImages->appendChild($this->_xmlDoc->createElement('ProductImage'));
$productImage->appendChild($this->_xmlDoc->createElement('ImagePath', $image));
}
if(isset($image['Url']) && is_array($image)) {
$productImage = $productImages->appendChild($this->_xmlDoc->createElement('ProductImage'));
$productImage->appendChild($this->_xmlDoc->createElement('ImagePath', $image['Url']));
}
}
}
This is how foreach looks 20 minutes after my question. So I'll vote for first answer, because its similar to my work around :)

I've encountered the same issue before with using a SOAP call. You don't need to change the structure of the array. You can simply change the behaviour of your foreach loop instead, using is_array. It checks if the variable is an array or not. Example, using your arrays:
$first_array = array(
"Images" => array(
array("Url" => "http://example.net/image1.jpg", "Default" => true),
array("Url" => "http://example.net/image2.jpg", "Default" => false),
array("Url" => "http://example.net/image3.jpg", "Default" => false)
)
);
$second_array = array(
"Images" => array(
"Url" => "http://example.net/image111.jpg",
"Default" => true
)
);
echo "Results on the first array:<br />";
foreach ($first_array["Images"] as $element) {
if (is_array($element)) {
foreach ($element as $value) {
echo $value . "<br />";
}
} else {
echo $element . "<br />";
}
}
echo "<br />";
echo "Result on the second array:<br />";
foreach ($second_array["Images"] as $element) {
if (is_array($element)) {
foreach ($element as $value) {
echo $value . "<br />";
}
} else {
echo $element . "<br />";
}
}
