引号中的wp_title

Question

I'm looking for a solution to this problem:

I want the wp_title on the single page to have a » mark before and a « mark after. Any suggestions?

<title><?php
    global $page, $paged;


    if (is_single()) {wp_title( '|', true, 'right' );}  //on this line

    else {wp_title( '|', true, 'right' );}

    bloginfo( 'name' );

    $site_description = get_bloginfo( 'description', 'display' );
    if ( $site_description && (is_front_page() ) )
        echo " | $site_description";

    ?></title>

Answer 1

This became the solution:

    <title><?php
    global $page, $paged;

    if (is_single()) {the_title('&raquo;', '&laquo;');echo ' | ';}
    else {wp_title( '|', true, 'right' );}

    bloginfo( 'name' );

    $site_description = get_bloginfo( 'description', 'display' );
    if ( $site_description && (is_front_page() ) )
        echo " | $site_description";

    ?></title>
