What are some common issues when trying to extract attributes from XML files using PHP?

One common issue when extracting attributes from XML files using PHP is not properly handling namespaces. If the XML file uses namespaces, you will need to specify them when accessing elements or attributes. To solve this, you can use the `->attributes()` method along with the namespace when extracting attributes. 

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

// Define the namespace
$ns = $xml->getNamespaces(true)['ns'];

// Extract attributes using namespaces
$attribute = $xml->children($ns)->element->attributes($ns)['attribute'];

echo $attribute;
