strategies for managing long class files in php

Question

I\'ve got a bunch of functions that I want to move into a class. They\'re currently split into a couple of fairly long files. I\'d prefer not to have one 2500 line file, but as

They are all in different files, which means that they were different enough to group by file. Just take the same logic when building them into classes. I have a Page object that deals with building the page. Technically the HTML for my page header is part of the page, but I separate it into a Page_HTML class for maintaining my sanity and not creating gigantic classes.

Also, I tend to make the sub_classes, like Page_HTML in this case, static, instead of instantiating it. That way I can access the $this variables in the Page class, but still group it into another class.

class Page
{
    function buildPage($content)
    {
        $content = Page_HTML::getHeader() . $content;
    }
}

class Page_HTML
{
    function getHeader()
    {
    }
}
