将javascript添加到php中的file_get_contents加载的html文件中

I am loading a html file by file_get_contents and make some changes over it and then echo it. I want to add a javascript code to the file but I don't know how to do it. Thanks in advance.

<?php
$page = file_get_contents('http://www.example.com/index.html');
$doc = new DOMDocument();
$doc->loadHTML($page);
$node = $doc->getElementById('something');
$node->parentNode->removeChild($node);
echo $doc->saveHtml($doc), PHP_EOL;
?>

    <?php
    
    $page = file_get_contents('http://example.com');
    $doc = new DOMDocument();
    $doc->loadHtml($page);
    
    $head = $doc->getElementsByTagName("head")->item(0);
    
    $js = $doc->createDocumentFragment();
    $js->appendXml("<script> alert(1); </script>");
    $head->appendChild($js);
    
    echo $doc->saveHtml();
    
    ?>
    

    This adds <script> alert(1); </script> to . Of course you can use "getElementById" and it be will exactly the same.

    Hope this helps.
