What potential pitfalls should be considered when working with large XML files in PHP?

When working with large XML files in PHP, potential pitfalls to consider include memory consumption and performance issues. To mitigate these problems, it is recommended to use XMLReader, a PHP extension that provides a stream-oriented API for reading XML documents. This allows you to process XML data incrementally without loading the entire document into memory. 

$reader = new XMLReader();
$reader->open('large.xml');

while ($reader->read()) {
    // process XML data here
}

$reader->close();
