Get page content and execute shortcodes on a page

function get_page_func( $atts ){
    extract(shortcode_atts( array(
        'title' => ''
    ), $atts ) );

    $page = get_page_by_title($title);

    $args = array(
        'include' => $page->ID,
    ); 
    $pages = get_pages($args); 

    $html = $pages[0]->post_content;

    $html = do_shortcode($html);

    return $html;
}

add_shortcode( 'get_page', 'get_page_func' );

Use above code. Wherever you require shortcode to be executed just use the following line

echo do_shortcode(‘get_page’);

This will work for PHP page and also work if you use a shortcode in post or page created using dashboard.
