To insert an XML sub-category in PHP, you can use the SimpleXMLElement class provided by PHP. Here is an example code snippet to show you how to do it:

// Load the XML file
$xml = simplexml_load_file('data.xml');

// Create a new sub-category element
$subCategory = $xml->addChild('sub-category');
$subCategory->addChild('name', 'Sub-category Name');
$subCategory->addChild('description', 'Sub-category Description');
$subCategory->addChild('image', 'sub-category.jpg');

// Save the changes back to the XML file
$xml->asXML('data.xml');

echo "Sub-category inserted successfully!";

In this code snippet, we first load the XML file using the simplexml_load_file() function. Then, we use the addChild() method to add a new sub-category element to the XML file. We set the attributes of the sub-category element such as name, description, and image using the addChild() method again. Finally, we save the changes back to the XML file using the asXML() method.

Make sure to replace 'data.xml' with the path to your actual XML file.
