You should have an asset management system in your PHP to see whats being included into the page.

Ultra simple example (derived from link):

';
    }
    static function render_content() {
        echo self::$content;
    }
    static function read_content($file) {
        ob_start();
        require $file;
        self::$content = ob_get_clean();
    }
    static function render_layout($file) {
        require $file;
    }
    static function add_js($js) {
        if (!in_array($js, self::$js_assets)) {
            self::$js_assets[] = $js;
        }
    }
}

Page::add_js('/javascripts/application.js');
Page::read_content('view.php');
Page::render_layout('layout.php');
?>

layout.php:

view.php:

Hello World!'); ?>
Hello
World
