How can the "unterminated entity reference" error be resolved when creating XML files in PHP?

The "unterminated entity reference" error in XML files occurs when special characters like "&" are not properly encoded. To resolve this issue, you can use PHP's htmlspecialchars() function to encode these special characters before writing them to the XML file. 

// Example PHP code snippet to resolve "unterminated entity reference" error in XML files
$data = "<example_data>This & That</example_data>";
$encoded_data = htmlspecialchars($data, ENT_QUOTES, 'UTF-8');

$xml = '<?xml version="1.0" encoding="UTF-8"?>
<root>
    <data>' . $encoded_data . '</data>
</root>';

file_put_contents('example.xml', $xml);
