What best practices should be followed when working with large XML files in PHP?

When working with large XML files in PHP, it is important to avoid loading the entire file into memory at once to prevent memory exhaustion. Instead, it is recommended to use XMLReader, a pull-based parser that allows for sequential access to the XML data without loading the entire document into memory. 

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

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

$reader->close();
