How to insert PHP variable into section of javascript, using DOMDocument?

I am using DomDocument to modify a HTML file that is resaved in a new folder.

There are a few PHP variables I am adding into the HTML elements, but I need to be able to add some variables into a section of javascript.

How can I achieve this?

Alternatively, is there any other way to take a HTML file and insert PHP variables into it and save the result? Maybe a super basic and lightweight template engine? (Must be able to read the HTML into memory)

Example HTML:

<html>
    <body>
        <script>
        var my_array = new Array();
        </script>
    <body>
</html>

Example PHP:

$doc->DOMDocument();
$doc->loadHTML($html_from_file);

// somehow need to target my_array;

$doc->saveHTMLFile($filename);

I do not know if I understand very well your question but in principle you could access the script tag in the DOM as any other tag with, for example:

$script = $doc->getElementsByTagName('script')->item(0) // if you want the first match

Now you can retrieve and modify, if needed, its content with the nodeValue property.

You can just create a script tag with PHP, like this:

echo "<script>var blah = $blah;</script>";
