I\'ve got a HTML page, the first thing the body does is include the top banner div and the navigation bar div:

Body for main html file:

    Yes there is, it works with output buffering and the HTML standard.

    First of all you need to enable output buffering:

    <?php
    ob_start(); // <<== Enabling output buffering
    require_once "article_functions.php";
    include "widgets/topborder.html";
    include "widgets/banner.php";
    include "widgets/navbar.html";
?>

    Then when you're done (at the end of the script), you read back in the buffer, parse the HTML and move the style elements from within the body tag into the head:

    $buffer = ob_get_clean();

$doc = new DOMDocument();
$doc->loadHTML($buffer);

$head = $doc->getElementsByTagName('head')->item(0);

$xpath = new DOMXPath($doc);
foreach ($xpath->query('//body//style') as $bodyStyle) {
    $head->appendChild($bodyStyle);
}

echo $doc->saveHTML();

    This will then output the HTML according to your changes:

    <html><head><style type="text/css">
        #banner_area {
            height: 30px;

            ...

    Hope this helps.
