是否有符合标准的方法来启动PHP会话并在一个include（）语句中回显JavaScript脚本？

I have two scripts that I call with two PHP include() calls. The first starts a session / sets cookies, the second loads one of two JavaScript scripts. To keep things valid, I've been using the two calls but I'd like to just combine them into one.

Current setup (simplified):

<? include "session.php" ?>
<!DOCTYPE HTML>
<html>
<head>
<? include "scripts.php" ?>
 ...

What I'd like:

<? include "session_and_scripts.php" ?>
<!DOCTYPE HTML>
<html>
<head>
...

But it's invalid markup. Now if it really doesn't matter, I'd like to do it this way. If there are serious repercussions, then I'm thinking of just echoing a DOCTYPE in the included PHP file, which I'd rather not do.

So which is better: echo the DOCTYPE, use include() twice, or use include() once and have invalid markup?

EDIT - The whole script (session and javascript) should ideally be fully implementable with one line of code (e.g. the one include())

    Use ob_start at first to avoid problems with session_start

    <?php ob_start();?>
<!DOCTYPE HTML>
<html>
<head>
<?php include "session_and_scripts.php"; ?>

    A way that uses only 1 1file and no additional instructions: 

    <?php include "session_and_scripts.php" ?>
<!-- more head-stuff-->
</head>
<body>
<!--more content-->

    session_and_scripts.php should do the following:

    <?php
  //do the session stuff
?>
<!DOCTYPE HTML>
<html>
<head>

<script type="text/javascript">
  //some javascript
</script>

    (But I would'nt say it's a good approach)
