How to convert a php stdclass object to xml?

To convert a PHP stdClass object to XML, you can use the built-in SimpleXMLElement class. Here's an example:

 9
10
11

// Assuming you already have a stdClass object $data

// Create a new SimpleXMLElement object
$xml = new SimpleXMLElement('<root></root>');

// Function to convert the object to XML recursively
function convertToXml($object, $xml)
{
    foreach ($object as $key => $value) {
        if (is_array($value)) {
            $subnode = $xml->addChild($key);
            convertToXml($value, $subnode);
        } else {
            $xml->addChild($key, $value);
        }
    }
}

// Convert the stdClass object to XML
convertToXml($data, $xml);

// Output the XML
echo $xml->asXML();

In this example, the $data variable represents your stdClass object. The convertToXml() function is a recursive function that traverses the object's properties and adds them as child elements to the XML object. Finally, the $xml->asXML() method is used to retrieve the XML representation of the object.

You can further enhance this by adding error handling and making the function more robust according to your specific needs.

It's worth mentioning that this code assumes that the stdClass object contains only scalar values and arrays. If your object contains nested objects, or if you want more control over the XML structure, you may need to modify the code accordingly.

Here's an example that handles nested objects:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14

function convertToXml($object, $xml)
{
    foreach ($object as $key => $value) {
        if (is_array($value)) {
            $subnode = $xml->addChild($key);
            convertToXml($value, $subnode);
        } elseif (is_object($value)) {
            $subnode = $xml->addChild($key);
            convertToXml((array)$value, $subnode);
        } else {
            $xml->addChild($key, $value);
        }
    }
}

In this modified code, if a property value is detected as an object, it is first cast to an array using (array)$value and then passed to the recursive function.

Remember to ensure that the names of the stdClass object's properties are valid XML element names. If they contain characters that are not allowed in XML element names (e.g., spaces or special characters), you will need to handle this by either modifying the property names or implementing custom logic to sanitize them before adding them as XML elements.
