What potential issues can arise when trying to import nodes from one HTML file to another using PHP?

One potential issue that can arise when importing nodes from one HTML file to another using PHP is that the imported nodes may not be rendered correctly due to missing styles or scripts from the original file. To solve this issue, you can use PHP's file_get_contents function to read the contents of the HTML file and then use DOMDocument to parse and import the nodes into the new file while preserving their styles and scripts. 

// Read the contents of the original HTML file
$original_html = file_get_contents('original.html');

// Create a new DOMDocument
$dom = new DOMDocument();
$dom->loadHTML($original_html);

// Get the body content of the original file
$body = $dom->getElementsByTagName('body')->item(0);

// Import the nodes from the original file into the new file
$new_dom = new DOMDocument();
$new_dom->loadHTMLFile('new.html');
$new_body = $new_dom->getElementsByTagName('body')->item(0);
foreach ($body->childNodes as $node) {
    $imported_node = $new_dom->importNode($node, true);
    $new_body->appendChild($imported_node);
}

// Save the new HTML file with imported nodes
file_put_contents('new.html', $new_dom->saveHTML());
