wordpress custom php page

        <?php
        // If title is not displayed before loading the header, Wordpress displays "Page not found" as the title

        echo "<head>
        <title>I test somthing</title>
        </head>";
        // Wordpress path (if wordpress is not located at ROOT//
        $wplocalpath="/Wordpress1";
        // Include the Main Wordpress blog header
        include $_SERVER['DOCUMENT_ROOT'].$wplocalpath."/wp-blog-header.php";

        //Now, you need to get the active theme's folder, and get a relative path to that folder

        $homeurl=home_url();
        $ddir= get_bloginfo( 'template_directory');
        $current_theme_relative_path=substr_replace($ddir, "", 0, strlen($homeurl));
        //echo "<br/>The relative path to the currently active theme is ".$current_theme_relative_path;

        //Once you have the path, include the header and footer, adding your custom php code in between.
        // Include the specific theme header you need

        include $_SERVER['DOCUMENT_ROOT'].$wplocalpath.$current_theme_relative_path."/header.php";

        // Your custom PHP code STARTS here

        // Add anything you want to display to the user
        echo "
        <h2>
        Your form has been submitted
        </h2>";

        // END of custom code


        // Now end with the theme's footer
        include $_SERVER['DOCUMENT_ROOT'].$wplocalpath.$current_theme_relative_path."/footer.php";
