Show your actual code. We are not declaring function like function_name($variable){}. The right syntax is function function_name($variable) {} — Yogesh Suthar

your code is error.. You should wrapped the code which inside the html_header function whith echo, and html_header() is a function, so you need add a function keyword before it.

That error happens because you put HTML tags directly in your PHP source (it's a syntax error). I guess you meant using echo on them?

And, in general, saving yourself from boilerplate code in this manner isn't a good idea. Better create templates or use an MVC framework.
