How can one debug PHP code to identify undefined properties like "usertype" in Joomla?

To debug PHP code and identify undefined properties like "usertype" in Joomla, you can enable error reporting and check for notices and warnings. You can also use functions like isset() or property_exists() to check if a property is defined before accessing it. Additionally, you can use var_dump() or print_r() to inspect the object's structure and properties. 

// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Check if the property "usertype" is defined before accessing it
if(property_exists($object, 'usertype')) {
    // Access the property if it is defined
    $userType = $object->usertype;
} else {
    // Handle the case when the property is undefined
    echo "Property 'usertype' is not defined.";
}
