直接上代码吧

复制代码代码如下:<?phpif(is_category()){single_cat_title();}elseif(is_single() || is_page()){single_post_title();}elseif(is_search()){echo wp_specialchars($s);}else{wp_title('',true);}if(! is_home()){echo ' - ';}?>post_content)), 0, 200, '...');$KEYwords = $post->post_title;}elseif(is_category()){$description = trim(strip_tags(category_description($cat_ID)));$keywords = single_cat_title('', false);}elseif(is_tag()){$keywords = single_tag_title('', false);$description = trim(strip_tags(tag_description($tag_ID)));}elseif(is_single()){if($post->post_excerpt){$description = $post->post_excerpt;}else{$description = mb_strimwidth(strip_tags(apply_filters('the_content', $post->post_content)), 0, 200, '...');}$keywords = $post->post_title;}else{$keywords = 'PHP博客,PHP,MySQL,Linux,C,编程算法,网站架构,互联网';$description = '专注WEB开发,热爱PHP/MySQL/Linux/C/编程算法/网站架构,崇尚自由关注互联网';}?>
