事后用PHP修改页面标题

Question

I would like to be able to change the page title with PHP. Now before you all answer with

<title><?php echo $title; ?></title>

I have a limitations... I am developing a plugin where my PHP is only inserted into the body of the page. Therefore <title> has already been defined and I would like to change it. Any ideas?

Edit: I am aware that this can be easily done with javascript. However, for SEO purposes I do not want to. I would like the actual contents of the <title> tag to be modified.

Answer 1

Insert a JavaScript snippet, that changes the title. As the if your PHP code is inserted, the header part is already streamed, so you have no way of getting that back.
