How can i get the title i specified in add_options_page for my header

There are a few ways you can do this. My preferred way of doing this is using Object Oriented Programming (OOP) to structure the plugin. For example, I might do this:

class JPBTitle {
  var $page_title = "Post Products Settings";

  function __construct(){
    add_action( 'admin_menu', array( $this, 'admin_menu' ) );
  }

  function admin_menu(){
    add_options_page( $this->page_title, $this->page_title, 'administrator', 'pp_settings', array( $this, 'pp_settings' ) );
  }

  function pp_settings(){
    echo "<div class="wrap">\n\t<h2>$this->page_title</h2></div>";
  }
}

$JPBTitle = new JPBTitle();

There are many many advantages to using object oriented programming in plugins; however, if you don’t want to use OOP, I would suggest either setting a global variable or defining a constant with the value you want to use for that string.
