WordPress优化之处理部分WordPress核心代码或功能，让你的网站更快

add_action( 'admin_bar_menu', 'cwp_remove_wp_logo_from_admin_bar_new', 25 );
function cwp_remove_wp_logo_from_admin_bar_new( $wp_admin_bar ) {
    $wp_admin_bar->remove_node( 'wp-logo' );
}

加载的css和js后面的版本号的问题

if(!function_exists('cwp_remove_script_version')){
    function cwp_remove_script_version( $src ){  return remove_query_arg( 'ver', $src ); }
    add_filter( 'script_loader_src', 'cwp_remove_script_version' );
    add_filter( 'style_loader_src', 'cwp_remove_script_version' );
}

WP前台顶部清理

function cwp_header_clean_up(){
    if (!is_admin()) {
        foreach(array('wp_generator','rsd_link','index_rel_link','start_post_rel_link','wlwmanifest_link') as $clean){remove_action('wp_head',$clean);}
        remove_action( 'wp_head', 'feed_links_extra', 3 );
        remove_action( 'wp_head', 'feed_links', 2 );
        remove_action( 'wp_head', 'parent_post_rel_link', 10, 0 );
        remove_action( 'wp_head', 'start_post_rel_link', 10, 0 );
        remove_action( 'wp_head', 'adjacent_posts_rel_link', 10, 0 );
        foreach(array('single_post_title','bloginfo','wp_title','category_description','list_cats','comment_author','comment_text','the_title','the_content','the_excerpt') as $where){
         remove_filter ($where, 'wptexturize');
        }
        /*remove_filter( 'the_content', 'wpautop' );
        remove_filter( 'the_excerpt', 'wpautop' );*/
        wp_deregister_script( 'l10n' );
    }
}
