How can error handling be implemented effectively when dealing with large XML files in PHP to prevent issues like memory exhaustion or parsing errors?

When dealing with large XML files in PHP, it is important to implement error handling to prevent issues like memory exhaustion or parsing errors. One way to do this is by using the XMLReader class, which allows you to read XML files incrementally without loading the entire file into memory. Additionally, you can use try-catch blocks to catch any exceptions that may occur during parsing. 

<?php

$xmlFile = 'large_xml_file.xml';

$reader = new XMLReader();
$reader->open($xmlFile);

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

$reader->close();

?>
