I'd like know if having the title tag positioned at the end of `<head>` tag or in any other position, always inside the `<head></head>`, can lead to some kind of problem, I'm not talking about SEO stuffs, I'm talking about standards, browser rules, web application rules, or something like this.

I'd like to load a page from two different php file like this, is it a wrong way?

```
<!-- file1.php -->
<html>
<head> 
....

<!-- file2.php -->
<title><?php echo($var)?>
</head> 
<body>
...

```

`<head>` tag is not closed, because with the second file I dynamically add the `<title>` tag.
