Php Title & Meta Tag

I need someone to help me create a PHP and meta tag script.

Basically heres what I have in mind, but I do not exactly know if its correct.

My content module uses ?page,

therefore the title would be like this in the index:

<title>My website - <? Page title?></title>

And something like this would be on the content file:

<title>Contact Us</title>

So basically I need a script that takes the title in my content box and puts it in the index title.

The same script should also be used for meta tags.

You can see what i mean by my content module..

P.s. I found this on the internet:

Would that work?

 

I think you have your full answer already in front of you
That would work just as you described.
Define the title in a variable and then echo it as in the example
